Functional crane equipment provides a mixed control system - pneumatic and hydraulic. The drums and shaft devices are driven actively by pneumatic chamber couplings, and the crane can be made to move in the other direction using a reversing mechanism. The crane speed can be easily adjusted using a turbo transformer. This functional element consumes energy from the crane's hydraulics.

The running gear receives supports with screw jacks. A heavy vehicle moves freely along the site with a load at a speed of up to three kilometers per hour. By rail, equipment can be transported on a platform. Before loading onto it, craftsmen must remove all the wheels and separate the boom sections. They need to be laid from top to bottom. A crane with a lifting capacity of twenty-five tons is used for loading.
If it is necessary to transport KS-4361 or KS-4361A over a considerable distance, you will need to use a tractor and a tow hitch, that is, tow it. To do this, the gearbox is set in neutral, the driveshaft is removed, and the steering cylinders are turned off. Traffic often moves at speeds of up to twenty kilometers per hour. But when turning, it is better to reduce it by about six to seven times.

Characteristics of the main and replaceable boom equipment of the KS-4361 crane

All actuators of the mechanisms on the KS-4361 crane are driven through a turbotransformer 35 .
The landing of the drums of the boom, cargo and auxiliary (grab) mechanisms is on a common shaft; thus, one three-drum winch is used.

Power take-off from engine to compressor 32 carried out using V-belt transmission 43 - 44 and cardan shaft 33 .
Rotation by motor 34 turbo transformer 35 transmitted through a coupling 20 , the output shaft of the turbo transformer is connected by a chain drive 15 - 36 with shaft 9 reverse mechanism.
Shaft 10 three-drum winch connected to a shaft 9 bevel reverse gear 16 - 22 and chain transmission 18 - 23 , and the gear 16 and an asterisk 23 have a rigid fit on the shafts, and the sprocket 18 and gear wheel 22 rotate freely. 19 They are activated using pneumatic chamber couplings 14 And 10 , planted on shafts. Depending on which gear is engaged (chain or gear), the shaft
forward or reverse rotation is reported. 13 As can be seen from the diagram, the boom drum 12 , cargo drum 11 main lift and cargo drum
auxiliary lifts have a free fit on the shaft and are kept from rotation by band brakes. The drums are turned on using pneumatic chamber couplings; 9 At the same time, the drums are released. 8 On the shaft 7 bevel gears rotate freely 28 that are in constant mesh with a gear 8 vertical shaft 28 .
By alternately engaging the pneumatic chamber clutches of the gears 6 shaft reversal is ensured 24 They are activated using pneumatic chamber couplings 26 (rotation clockwise or counterclockwise). 26 Gears 27 , gears 29 are in constant mesh, and the gear wheel 25 freely mounted on the shaft. It is activated using a claw clutch 5 , while the shaft
starts to rotate. 24 The gear rotates together with the shaft 26 , rolling along the ring gear 24 ; 30 the rotary part of the crane rotates. 31 Gear 45 - 46 , being in constant engagement with the gear wheel 55 , when it rotates, it also rotates, and since the gear wheel
By alternately engaging the pneumatic chamber clutches of the gears 4 has a keyed connection to the shaft 48 , the shaft rotates with it. Next, the rotation is transmitted to the shaft using an equalizing coupling 55 , bevel gear 49 and shaft 53 , and therefore the speed of movement of the crane.
starts to rotate. 51 the intermediate shaft is in constant mesh with the gear 50 output shaft 54 , which using cardan shafts 41 They are activated using pneumatic chamber couplings 52 drives the front and rear axles.
The front and rear axles of the crane include differential devices that allow the right and left wheels to rotate at different speeds, which is very important when the crane moves along curved sections of the track.
Input gear 40 the main gear is in constant engagement with the gear 42 , sitting on the splines of the intermediate shaft. From the intermediate shaft of the main drive, rotation is transmitted through gears 38 They are activated using pneumatic chamber couplings 39 onto the differential housing and through the satellites (gears) 3 and sun gear 2 - on the axle shaft of the crane wheels.

On the KS-4361 crane with a single-engine drive, when considering the kinematic diagram of its mechanisms, the concept of a main and auxiliary lift winch is not fully applicable, since the layout of the mechanisms with a single-engine drive does not allow one to clearly distinguish one or another winch; many elements of the kinematic chain of mechanisms are transmissions for a number of executive bodies. Therefore, this crane considers only the design of mechanisms directly connected to the executive bodies - the drums.

On a common shaft 6 three drums are mounted: cargo 3 , auxiliary (grab) 18 and boom 5 . 1 , 7 has a keyed connection to the shaft 14 All three drums have a ball bearing fit and rotate freely on the shaft.
The drums are turned on using pneumatic chamber couplings 2 They are activated using pneumatic chamber couplings 10 , rigidly connected to the shaft, and are kept from free rotation or from rotation under the action of loads (loaded ropes) using band brakes. 9 The shaft rotates in double-row spherical support bearings 11 and is driven by a sprocket 12 or gear 19 with ball bearing support. The wheel is driven by a pneumatic clutch 11 .
.
Reversing the shaft is carried out by engaging a chain transmission using a pneumatic chamber clutch 17 , mounted on the reversible shaft, or by turning on a gear 16 The operating principle of a pneumatic chamber clutch is based on the friction of the tire against the surface of the drum pulley under the influence of compressed air. The type of coupling according to the nature of the connection is frictional; by the nature of the work and main purpose - to the class of controlled and coupling couplings that allow you to open and close the connections of the part. 15 . 6 Air is supplied to the pneumatic chambers through rotating swivel joints from the ends of the shaft 5 (through the channels in it) and from the shaft - to the chambers (through flexible hoses). When supplying compressed air through a hose 15 the latter expands into the chamber and presses the friction tape with the tire 3 .
to the inner surface of the drum pulley 3 The brake band is adjacent to the outer surface of the drum pulley. Ribbon 1 consists of two parts connected by a coupling bolt 12 . 7 One end of the tape is hinged with a pin on the gusset, the other end is connected to the eyelet 6 . 7 The eye is connected to the rod using a lever system 9 hydraulic cylinder 11 . 12 The brake control is hydraulic. When you press the hydraulic cylinder pedal with your foot, the piston moves to the left and through the rod 8 and a fork 2 .
turns the lever
.
In this case the eye 19 moves up and the brake is applied (the drum is braked). 18 If you remove your foot from the pedal, the hydraulic cylinder piston is under the action of a spring 4 will return to its original position (the drum will be released). 16 A spring is used to ensure uniform release of the brake band from the drum pulley. 15 A brake of a similar design is installed on a clamshell (auxiliary) drum. 1 The boom drum is equipped with two band brakes: permanently closed and adjustable. 2 Eye 3 permanently closed brake mounted on a bracket 17 .

Rotation mechanism is driven by a common motor for all crane mechanisms. 27 Bevel gear 14 The reversible mechanism for rotation and movement of the crane is constantly engaged with bevel gears sitting on the reversible shaft. 15 Vertical shaft loads 8 are supported at the top by a deep groove ball bearing, and at the bottom by a thrust ball bearing and a double-row spherical roller bearing. A gear is firmly seated at the lower end of the vertical shaft 12 meshing with a gear wheel 12 , freely sitting on a vertical shaft 8 . 13 On the shaft 10 besides the gear 23 placed brake pulley 14 , gear coupling 10 and gear 12 ; 7 they are all rigidly connected to the shaft. During shaft rotation 5 and with the clutch disengaged 7 the gear wheel rotates freely on the shaft
and transmits rotation to the gear wheel 10 , sitting rigidly on the shaft 12 . Together with gear wheel 23 the vertical shaft rotates and thus the power is transferred to the movement mechanism. 22 When the clutch is engaged 5 the shaft starts to rotate
and gear
the ring gear begins to run around 17 , 19 ; 22 the turntable begins to rotate relative to the central shaft

. The ring gear has internal gearing. 12 As can be seen from the diagram, the platform rotation gearbox simultaneously plays the role of a crane movement gearbox. 6 Outer rings 17 connected not to the frame of the undercarriage, but to the turntable; 5 inner ring 6 connected to the fixed frame of the undercarriage. Thus, the inner ring is stationary and plays the role of the base of the slewing bearing. 4 Front axle 2 crane KS-4361 - controlled, leading; 6 its suspension to the frame is balanced, which improves the grip of the wheels with the base on uneven roads.
Power transmission from the propeller shaft to axle shafts 18 The front axle also has a cylindrical main gear, just like the rear axle. 5 so that the protrusion of the driver falls between the wheel rim stops. The leash is fixed with a bolt 19 .
Lower arms of housings 17 connected to each other by a transverse rod 14 steering trapezoid.
The upper arms of the housings are connected to the rods of the turning hydraulic cylinders, which are mounted on the axle housing bracket. 12 Rotation of the drive wheels from the axle shaft 4 to the axle shaft 15 They are activated using pneumatic chamber couplings 16 .
transmitted through articulated joints Rear axle
crane KS-4361 - leading. The bridge is of an automobile type, its suspension to the frame is rigid. It uses assembly units of the KrAZ vehicle, including the main gear with differential, axle shafts and brakes.

The fastening of the running wheels is discless; it is carried out with clamps and rings. .
The main gear of the rear axle is cylindrical.

The bevel gear serves to connect intersecting shafts and regulate movement.

On the KS-4361 crane, between the engine and transmission, instead of the main friction type clutch, a special hydraulic device is installed - a torque converter 1 TRK-325 2 The torque converter provides stepless regulation of the speed of lifting and lowering a load, reversing the direction of movement, lifting small loads at increased speed, and changing the speed of movement depending on the resistance to movement. 3 Torque converter diagram TRK-325 4 The torque converter TRK-325 includes a housing in which the pumping unit is coaxially located
, turbine 5 and guide 6 (reactor) wheels. 7 The reactor is rigidly connected to the housing. 4 They are activated using pneumatic chamber couplings 8 .
The driving pump wheel receives movement from the shaft 8 engine, and the turbine (driven) is connected to the driven shaft.

Radiator serves to cool the working fluid passed through it using a gear pump.

The transformer is equipped with a bypass valve, filter and hydraulic tank

The air is pre-compressed in the first stage of the compressor 13 , passes through the refrigerator and oil-moisture separator and is compressed in stage II to 0.6 - 0.7 MPa, from where it enters the receiver 16 and further through the pipeline 17 to the control panel 3 .
In the oil and moisture separator, the air is cleaned of moisture and oil, and then enters the second stage of the compressor.
From the control panel air through pipelines and special rotating joints 10 goes to pneumatic chamber couplings 7 crane mechanisms.
When each mechanism is turned off, air from the pneumatic chamber couplings is released into the atmosphere. To quickly release the crane mechanisms, special valves are installed in the turbo transformer systems, pneumatic chamber and brake couplings of the boom drum and the crane movement mechanism. 8 .
For smooth rotation of the platform, flow regulators are used in the systems of the reversing mechanism and the rotation brake, as well as the movement mechanism. 18 .
The crane mechanisms are controlled from the remote control using special devices - spool valves (valves). There are two types of spools: differential and direct acting.

Differential spools are used for those valve mechanisms that require regulation of external forces when turned on. Such mechanisms are mechanisms with friction clutches used in cranes with a single-engine drive - an internal combustion engine.

For mechanisms that do not require changes in pressure in the system, direct-acting spools are used. Control cabin of a crane with a single-engine drive KS-4361
Electrical equipment
the KS-4361 crane serves to power internal and external lighting, light and sound alarms, and a load limiter;
During the period when the diesel engine is stopped, the crane's electrical network is powered by a battery, which is also used to start the starting engine with an electric starter.
The magnitude of the battery charging and discharging current is determined using an ammeter.
The electrical system of the crane includes a set of converters installed on the engine, the oil tank of the turbo-transformer and the compressor. These converters make it possible, through appropriate devices, to control the temperature of water and diesel oil, the oil temperature in the turbotransformer, and the oil pressure in diesel and compressor systems.
The limit positions of the boom are fixed by a limit switch, which acts on the electromagnet circuit.
The latter controls the spool, which, when the boom reaches its extreme position and the switch is activated, turns off the turbo transformer and turns on the winch brake. The magnet receives power from the running diesel engine through a relay.

The electrical circuit provides a control button that allows you to bypass the limit switch and return the boom to the working position, as well as turn on the load limiter when it is triggered. The control panel has a button to turn on the sound signal. The portable repair lighting lamp is switched on via a plug socket.
For

load restrictions 2 The electric load limiter OGP-1 is used for the crane and automatic shutdown of the cargo winch. 1 When the crane operates at minimum boom radii, a stop with flexible elements is used to prevent it from tipping onto the turntable. 4 Rope traction 3 passes through deflection rollers

support the rope and prevent it from sagging. When the boom reaches the maximum angle of inclination (towards the turntable), the rope is tensioned and keeps the boom from further movement.

The set of working equipment includes a main boom with a length of 10 m, a hook with a lifting capacity of 16 tons and a grab with a capacity of 1.5 m3, mounted on 10- and 15-meter booms.

Characteristics of the main and replaceable boom equipment of the KS-4361A crane

Device - pneumatic wheel crane KS-4361A

The KS4361A crane is a diesel single-engine crane with a torque converter. The set of working equipment includes a main boom with a length of 10 m, a hook with a lifting capacity of 16 tons and a grab with a capacity of 1.5 m3, mounted on 10- and 15-meter booms. Replaceable equipment is extended booms with a length of 15, 20 and 25 m, obtained from the main boom by inserting 5-meter sections, and a non-steerable jib 6 m long. The boom is equipped with a limiter that protects it from tipping onto the platform when working at a minimum reach.

The KS4361A crane is a modernized model of the KS-4361 crane with a modified design of the body and driver's cabin. All main characteristics of the crane correspond to the basic model KS-4361.

The crane uses a mixed control system - pneumohydraulic. The winch and reverse shafts, as well as the drums, are activated using pneumatic chamber couplings; the direction of movement of the crane's turning and movement mechanisms is changed by a reversing mechanism and bevel gears. The inclusion of the reversing mechanism is also provided by pneumatic chamber couplings. The operating speeds of the crane are regulated over a wide range using a turbo transformer powered by the crane's hydraulic system.

The running gear of the crane is equipped with outriggers with screw jacks having small shoes at the ends. The crane can move around the site under its own power, including with a load on the hook, at a speed of up to 3 km/h. Movement with a load on a hook is allowed on the platform with a boom of 10 - 15 m, directed along the longitudinal axis of the crane.

Over long distances along highways, the crane is towed to a tractor using a coupling device. During the process of relocating the crane, the gearbox is set to the neutral position, the wheel steering cylinders are turned off, and the driveshaft of one of the axles is removed. The towing speed should not exceed 20 km/h, and on slopes and turns the speed should be reduced to 3 km/h.

The crane is transported by rail on a four-axle platform. Before loading the crane onto the platform, all pneumatic wheels are removed, the boom sections are separated, placing the upper section on the lower one. The crane is loaded onto the platform using an assembly crane with a lifting capacity of 25 tons. If there are replaceable boom sections, they are laid on the second platform.

All the executive bodies of the mechanisms on the KS-4361 crane are driven through a turbotransformer 35. The landing of the drums of the boom, cargo and auxiliary (grab) mechanisms is on a common shaft; thus, one three-drum winch is used.

Power is taken from the engine to the compressor 32 using a V-belt transmission 43 - 44 and a cardan shaft 33. Rotation from the engine 34 to the turbotransformer 35 is transmitted through coupling 20, the output shaft of the turbotransformer is connected by a chain transmission 15 - 36 to the shaft 9 of the reversing mechanism. Shaft 10 of the three-drum winch is connected to shaft 9 of the conical reverser by a gear 16 - 22 and a chain drive 18 - 23, and gear 16 and sprocket 23 have a rigid fit on the shafts, and sprocket 18 and gear 22 rotate freely. They are activated using pneumatic chamber couplings 19 and 14 mounted on the shafts. Depending on which gear is engaged (chain or gear), shaft 10 is given direct or reverse rotation.

As can be seen from the diagram, the boom drum 13, the main lift cargo drum 12 and the auxiliary lift cargo drum 11 have a free fit on the shaft and are kept from rotating by band brakes. The drums are turned on using pneumatic chamber couplings; At the same time, the drums are released. On shaft 9, bevel gears 8 rotate freely, which are in constant mesh with gear 7 of vertical shaft 28. Alternately engaging the pneumatic chamber couplings of gears 8 ensures reversal of shaft 28 (rotation clockwise or counterclockwise).

Gears 6, gears 24 and 26 are in constant mesh, and gear 26 is freely mounted on the shaft. It is turned on using the cam clutch 27, and the shaft 29 begins to rotate. Gear 25 rotates together with the shaft, rolling along ring gear 5; the rotary part of the crane rotates. Gear 24, being in constant engagement with gear 26, also rotates when it rotates, and since gear 24 has a keyed connection with shaft 30, the shaft also rotates with it. Next, the rotation is transmitted using an equalizing clutch to shaft 31, bevel gear 45 - 46 and shaft 55 of the chassis gearbox. Gears 4 and 48 rotate freely on shaft 55. They are alternately engaged using a cam clutch 49. Depending on which gear is engaged by the clutch, the rotation speed of shaft 53 changes, and therefore the speed of movement of the crane.

The intermediate shaft gear 51 is in constant mesh with the gear 50 of the output shaft 54, which drives the front and rear axles with the help of cardan shafts 41 and 52.

The front and rear axles of the crane include differential devices that allow the right and left wheels to rotate at different speeds, which is very important when the crane moves along curved sections of the track.

The input gear 40 of the main transmission is in constant mesh with the gear 42, sitting on the splines of the intermediate shaft. From the intermediate shaft of the main drive, rotation is transmitted through gears 38 and 39 to the differential housing and through satellites (gears) 3 and sun gear 2 to the axle shafts of the crane wheels. On the KS-4361 crane with a single-engine drive, when considering the kinematic diagram of its mechanisms, the concept of a main and auxiliary lift winch is not fully applicable, since the layout of the mechanisms with a single-engine drive does not allow one to clearly distinguish one or another winch; many elements of the kinematic chain of mechanisms are transmissions for a number of executive bodies. Therefore, this crane considers only the design of mechanisms directly connected to the executive bodies - the drums.

Multi-drum winch - KS-4361A.

Three drums are mounted on a common shaft 6: cargo 3, auxiliary (grab) 18 and boom 5. All three drums have a ball-bearing fit and rotate freely on the shaft. The drums are activated using pneumatic chamber couplings 1, 7 and 14, rigidly connected to the shaft, and are kept from free rotation or from rotation under the action of loads (loaded ropes) using band brakes.

The shaft rotates in double-row spherical bearings of supports 2 and 10 and is driven by a sprocket 9 or a gear 11 with a ball bearing support. The wheel is driven using a pneumatic clutch 12. The shaft reversal is carried out by engaging a chain transmission using a pneumatic chamber coupling 19 mounted on the reversing shaft, or by engaging a gear wheel 11.

The operating principle of a pneumatic chamber clutch is based on the friction of the tire against the surface of the drum pulley under the influence of compressed air. The type of coupling according to the nature of the connection is frictional; by the nature of the work and main purpose - to the class of controlled and coupling couplings that allow you to open and close the connections of the part.

The coupling consists of a pulley 17, a pneumatic chamber 16 and a tire 15. Air is supplied to the pneumatic chambers through rotating swivel joints from the ends of the shaft 6 (through channels in it) and from the shaft to the chambers (through flexible hoses). When compressed air is supplied through hose 5 into the chamber, the latter expands and presses the friction belt with tire 15 to the inner surface of the drum pulley 3.

Band brake for cargo and grab drums - KS-4361A

The brake band is adjacent to the outer surface of the drum pulley. The tape 3 consists of two parts connected by a coupling bolt 1. One end of the tape is hinged with a pin on the gusset, the second end is connected to the eye 12. The eye is connected to the rod 7 of the hydraulic cylinder 6 using a system of levers. The brake control is hydraulic. When you press the pedal of the hydraulic cylinder with your foot, the piston moves to the left and turns the lever 11 through the rod 7 and fork 9. At the same time, the eye 12 moves up and the brake is tightened (the drum is braked). If you remove your foot from the pedal, the hydraulic cylinder piston, under the action of spring 8, will return to its original position (the drum will be released). To ensure uniform withdrawal of the brake band from the drum pulley, spring 2 is used.

A brake of a similar design is installed on a clamshell (auxiliary) drum.

The boom drum is equipped with two band brakes: permanently closed and adjustable. Eye 19 of the permanently closed brake is mounted on bracket 18; the running end of the brake band is tensioned by spring 4. A ratchet wheel 16 is installed on the drum; with the help of pawl 15 the drum is kept from rotating. If it is necessary to lower the boom, the pawl is disengaged from the ratchet wheel using rod 1, lever 2 and pneumatic chamber 3. The stroke of the pneumatic chamber rod is limited by an adjustable (screw) stop 17.

The controlled brake band, like the brake band of a cargo winch, consists of two parts connected by a coupling bolt. The uniform withdrawal of the belt from the drum is regulated by a guy spring 6. The brake eye is mounted on the bracket 10 using a roller, on which a lever 12 is also installed, connected at one end to the eye of the brake belt 14, and at the other to the rod of the pneumatic chamber 9.

The tension of the brake band (braking of the boom drum) is carried out by spring 8 through rod 13, and the band is released using a pneumatic chamber. The main and auxiliary winches of jib cranes are equipped with special devices - rope handlers. They ensure correct laying of the rope drum in the grooves and prevent it from falling off the drum.

The turning mechanism is driven by a common motor of all crane mechanisms. The bevel gear 27 of the reversing mechanism for rotation and movement of the crane is in constant mesh with the bevel gears sitting on the reversing shaft. Loads on the vertical shaft 14 are perceived at the top by a radial ball bearing, and at the bottom by a thrust ball bearing and a double-row spherical roller bearing. At the lower end of the vertical shaft, a gear 15 is rigidly mounted, which meshes with a gear wheel 8, freely sitting on a vertical shaft 12. On the shaft 12, in addition to the gear wheel 8, there is a brake pulley 13, a gear coupling 10 and a gear 23; they are all rigidly connected to the shaft. During rotation of shaft 14 and with clutch 10 turned off, the gear wheel rotates freely on shaft 12 and transmits rotation to gear wheel 7, rigidly seated on shaft 5. Together with gear wheel 7, the vertical shaft rotates and thus power is transferred to the movement mechanism.

When clutch 10 is turned on, shaft 12 begins to rotate and gear 23 begins to run around ring gear 22; the turntable begins to rotate relative to the central shaft 5. The ring gear has internal gearing.

As can be seen from the diagram, the platform rotation gearbox simultaneously plays the role of a crane movement gearbox. The outer rings 17, 19 are connected not to the chassis frame, but to the turntable; the inner ring 22 is connected to the fixed frame of the undercarriage. Thus, the inner ring is stationary and plays the role of the base of the slewing bearing.

The front axle of the KS-4361 crane is steered, driven; its suspension to the frame is balanced, which improves the grip of the wheels with the base on uneven roads. The transmission of power from the cardan shaft to the axle shafts 12 on the front axle is also carried out by a cylindrical main gear, as on the rear axle. The inner wheels are mounted on the hub 6, which is mounted using tapered bearings on a pin mounted in the housing 17. Using a flange 5, the hub 6 is connected to the axle shaft 4. The outer wheels are mounted on the hub 2, which is mounted on the hub 6 using plain bearings; thus, the outer wheels are not driven, as they have a loose fit.

When a decrease in cross-country ability begins to affect the performance of the crane, the outer wheels are blocked with internal special drivers 18 installed on the flanges 5 so that the protrusion of the driver falls between the wheel rim stops. The leash is fixed with a bolt 19. The lower arms of the housings 17 are connected to each other by the transverse rod 14 of the steering linkage. The upper arms of the housings are connected to the rods of the turning hydraulic cylinders, which are mounted on the axle housing bracket.

Rotation of the drive wheels from axle shaft 12 to axle shaft 4 is transmitted through articulated joints 15 and 16. The rear axle of the KS-4361 crane is driving. The bridge is of an automobile type, its suspension to the frame is rigid. It uses assembly units of the KrAZ vehicle, including the main gear with differential, axle shafts and brakes. The fastening of the running wheels is discless; it is carried out with clamps and rings.

The main gear of the rear axle is cylindrical. The bevel gear serves to connect intersecting shafts and regulate movement. The traveling mechanism of the KS-4361 crane does not have a separate motor for the traveling mechanism; Power take-off in the gearbox is carried out using a vertical shaft 6 with a bevel gear 7 rigidly mounted on it. In mesh with it is a bevel gear 4, rigidly seated on the input shaft 5 of the gearbox.

The brake of the KS-4361 crane is installed on a bracket fixed to the body of the rear axle of the crane.

On the KS-4361 crane, instead of a main friction type clutch, a special hydraulic device is installed between the engine and transmission - a torque converter TRK-325. The torque converter provides stepless regulation of the speed of lifting and lowering a load, reversing the direction of movement, lifting small loads at increased speed, and changing the speed of movement depending on the resistance to movement.

The TRK-325 torque converter includes a housing in which the pump 1, turbine 2 and guide 3 (reactor) wheels are located. The reactor is rigidly connected to the housing. The driving pump wheel receives movement from the motor shaft 4, and the turbine (driven) wheel is connected to the driven shaft.

The radiator 5 serves to cool the working fluid passed through it using a gear pump 6. The transformer is equipped with a bypass valve, a filter and a hydraulic tank 7, as well as an overrunning clutch. At the same rotation speed of the turbine and pump wheels, the clutch connecting shafts 4 and 8 is activated.

Turn off the torque converter by removing fluid from the system. A brake controlled by the driver can be installed on shaft 8. To direct the movement of fluid in the system, a pneumatic pusher, spool valve, ejector and diffuser are used.

The pneumatic control system of the KS-4361 jib crane includes the following elements: a compressor, a refrigerator and an oil and moisture separator, a receiver, a control panel with a pneumatic distributor, pipelines and pneumatic chambers mounted on the actuators of the crane.

The air is pre-compressed in the first stage of the compressor 13, passes through the refrigerator and oil-moisture separator and is compressed in the second stage to 0.6 - 0.7 MPa, from where it enters the receiver 16 and then through the pipeline 17 to the control panel 3.

In the oil and moisture separator, the air is cleaned of moisture and oil, and then enters the second stage of the compressor. From the control panel, air flows through pipelines and special rotating joints 10 to the pneumatic chamber couplings 7 of the crane mechanisms.

When each mechanism is turned off, air from the pneumatic chamber couplings is released into the atmosphere. To quickly release the crane mechanisms, special valves 8 are installed in the systems of the turbo transformer, pneumatic chamber and brake couplings of the boom drum and the crane movement mechanism.

For smooth rotation of the platform in the systems of the reversing mechanism and the rotation brake, as well as the movement mechanism, flow regulators 18 are used. The crane mechanisms are controlled from the remote control with special devices - spool valves (valves). There are two types of spools: differential and direct acting. Differential spools are used for those valve mechanisms that require regulation of external forces when turned on. Such mechanisms are mechanisms with friction clutches used in cranes with a single-engine drive - an internal combustion engine. For mechanisms that do not require changes in pressure in the system, direct-acting spools are used.

The electrical equipment of the KS-4361 crane is used to power internal and external lighting, light and sound alarms, and a load limiter; provides starting of the starting engine, heating and ventilation of the control cabin, heating of the diesel engine. The source of direct current is the G-66 generator, which is also designed to charge the 6ST-42 battery. The generator is driven by a diesel engine through a gear drive.

To regulate the voltage and protect the generator, a relay regulator is provided, consisting of a voltage relay, a current limiter and a reverse current relay (prevents the battery from being discharged to the generator when the diesel engine is not running). Fuses are used to protect against short circuits.

During the period when the diesel engine is stopped, the crane's electrical network is powered by a battery, which is also used to start the starting engine with an electric starter. The magnitude of the battery charging and discharging current is determined using an ammeter.

The electrical system of the crane includes a set of converters installed on the engine, the oil tank of the turbo-transformer and the compressor. These converters make it possible, through appropriate devices, to control the temperature of water and diesel oil, the oil temperature in the turbotransformer, and the oil pressure in diesel and compressor systems.

The limit positions of the boom are fixed by a limit switch, which acts on the electromagnet circuit. The latter controls the spool, which, when the boom reaches its extreme position and the switch is activated, turns off the turbo transformer and turns on the winch brake. The magnet receives power from the running diesel engine through a relay.

The electrical circuit provides a control button that allows you to bypass the limit switch and return the boom to the working position, as well as turn on the load limiter when it is triggered.

The control panel has a button to turn on the sound signal. The portable repair lighting lamp is switched on via a plug socket.

To limit the crane's lifting capacity and automatically turn off the cargo winch, an electric load limiter OGP-1 is used. When the crane operates at minimum boom radii, a stop with flexible elements is used to prevent it from tipping onto the turntable.

The rope traction 2 passes through the deflecting rollers 1 on the boom 4 and is fixed on the platform. Springs 3 support the rope and prevent it from sagging. When the boom reaches the maximum angle of inclination (towards the turntable), the rope is tensioned and keeps the boom from further movement.

We will estimate the residual life based on the condition of the above-mentioned load-bearing metal structures of the crane.

Basic provisions.

The residual life is assessed depending on the type of damage according to the criteria:

Fatigue

Corrosion

Limited fatigue from operating state loads is checked by calculation:

Boom and its fastening elements

Outriggers

Fixed frame

Swivel frame

According to RD7, for cranes with a lifting capacity of up to 50 tons, it is allowed to determine the possibility of their further operation using a point system.

In this case, defects belong to three groups

1. Manufacturing and installation defects

Defects resulting from gross violation of normal operation.

Defects that arose during normal operation in the absence of defects in manufacturing and installation.

Each defect corresponds to a certain number of points, determined using a special table.

With a score of 5, the residual life of the crane is sufficient until the next inspection (after repair, the service life can be extended by 2 years).

If the number of points is from 5 to 10, defective load-bearing structures are replaced or repaired.

With a score of 10, it is considered that the crane has completely exhausted its service life.

The initial data for performing the residual life assessment are:

Results of inspection of a lifting machine in accordance with RD7

Number and results of previous crane inspections

Data characterizing the use of a lifting machine over the entire period of its operation (number of cycles, distribution of transported goods by mass, degree of environmental aggressiveness, etc.).

Data on the geometry of design elements of a metal structure taking into account corrosion.

For this faucet, the total number of points, according to the table below, is ___ 0,2 ______. This indicates that the crane’s life is sufficient until the next inspection in ____ 2 _____ year, subject to the elimination of defects identified during the inspection.

Self-propelled full-rotating single-engine diesel crane KS-4361 with a maximum lifting capacity of 16 tons, it is intended for construction and loading work with piece and bulk cargo at construction sites and warehouses.

The set of working equipment includes the main lattice hinged-folding a boom with a length of 10 m, a hook with a lifting capacity of 16 tons and a grab with a capacity of 1.5 m 3, hung on 10- and 15-meter booms. Replaceable equipment is extended booms with a length of 15, 20 and 25 m, obtained from the main boom by inserting 5-meter sections, and a non-steerable jib 6 m long. The boom is equipped with a limiter that protects it from tipping onto the platform when working at a minimum reach.

The crane uses a mixed control system - pneumohydraulic. The winch and reverse shafts, as well as the drums, are activated using pneumatic chamber couplings; the direction of movement of the crane's turning and movement mechanisms is changed by a reversing mechanism and bevel gears. The inclusion of the reversing mechanism is also provided by pneumatic chamber couplings. The operating speeds of the crane are regulated over a wide range using a torque converter powered by the crane's hydraulic system.

The running gear of the crane is equipped with outriggers with screw jacks having small shoes at the ends.

The crane can move around the site under its own power, including with a load on the hook, at a speed of up to 3 km/h. Movement with a load on a hook is allowed on the platform with a boom of 10 - 15 m, directed along the longitudinal axis of the crane.

Over long distances along highways, the crane is towed to a tractor using a coupling device. During the process of relocating the crane, the gearbox is set to the neutral position, the wheel steering cylinders are turned off, and the driveshaft of one of the axles is removed. The towing speed should not exceed 20 km/h, and on slopes and turns the speed should be reduced to 3 km/h.

The crane is transported by rail on a four-axle platform. Before loading the crane onto the platform, all pneumatic wheels are removed, the boom sections are separated, placing the upper section on the lower one. The crane is loaded onto the platform using an assembly crane with a lifting capacity of 25 tons. If there are replaceable boom sections, they are laid on the second platform.

Reference:

The KS-4361 crane has an improved modification - the KS-4361A model with a modified design of the body and driver's cabin.

The crane is not currently in production.
