The alignment of the tires on the bridge beam does not change, resulting in reduced tire wear.
Komatsu 960E
Impressive photo of himself large dump truck in the world of Japanese manufacturers, Komatsu, which works closely with Russian consumers. In the Kemerovo region, in the quarries of which more than 400 of the largest Japanese Komatsu trucks in the world operate, a service for the maintenance and repair of Japanese equipment has been established. Despite its impressive size and weight, the video clearly shows that Komatsu's largest dump truck is easy to operate. This is achieved by the design features of bridges and powerful system steering hydraulics.
BelAZ-75601
Model one of latest developments plant of the largest BelAZ dump trucks. The video of the world's largest dump trucks shows that the BelAZ-75601 was created on the basis of the BelAZ-75600. The differences in the photo are almost invisible; they are in individual elements that were taken from other manufacturers of the largest trucks in the world. Engine MTU 20V4000, 3.75 thousand hp, electric drive transmission, elements electronic diagnostics Siemens. Cabin with improved visibility, LCD monitor on the control panel.
Titan 33-19
The uniqueness of the once largest dump truck in the world shown in the photo is that it was produced by Terex in a single copy. After 13 years of productive work in the quarries of California and other fields, it was scrapped. But in 1993, wise people restored the most big truck and it is now on display as a historical landmark under Sparwood. Tourists enjoy taking photos of the largest mining dump truck in the world from the 70s of the last century.
Liebherr T 282B

This model of one of the world's largest dump trucks includes modern developments in special equipment of this class. The dump truck's load capacity is 363 tons, while the chassis is on two axles, so less rubber is required. Electric transmission alternating current. Since 2008, Bucyrus has merged with Liebherr and the Bucyrus line of largest dump trucks has become known as UnitRig.
Conclusion
The listed properties of the 10 largest mining dump trucks in the world show that global manufacturers offer consumers equipment with wide possibilities. Every year the productivity of dump trucks, labor safety on them, and comfortable working conditions are increasing.
With the release of the new HD 1500-7 model, Komatsu has expanded its range of rigid frame mining dump trucks.
New dump truck with a nominal lifting capacity of 144 t equipped diesel engine SDA12V160 1048 kW (1406 hp), with hydromechanical transmission and an automatic seven-speed transmission, oil-cooled multi-disc brakes with speed retarders on all four wheels and standard system automatic control driving speed (ARSC).
The diesel engine of the dump truck is characterized by the highest power in its class. In addition, it provides higher acceleration and travel speeds with high specific power (in hp per 1 ton of transported cargo). High torque at low engine speeds, impressive acceleration and low fuel consumption guarantee maximum truck performance. Engine in standard equipped electronic system Quantum control systems, Cummins Cense monitoring and pre-lubrication systems. The Komatsu torque converter, mounted in one block with a lock-up clutch, has electronic control operating modes and load.
The automatic gearbox and transmission of the dump truck are installed on elastic rubber cushions, which dampen and soften vibration impacts from the engine and shock when the vehicle moves along quarry roads. The transmission control hydraulic circuit consists of separate circuits, each of which is equipped with an additional cooler transmission fluid. The engine and hydraulic transmission provide the speed of the dump truck (empty, with a rolling resistance of 2%) in the range from 11 km/h in 1st gear to 58 km/h in 7th gear, and reverse- 9.4 km/h.
The dump truck is equipped with a spacious cabin with circular sealed glazing made of flat glass with a ROPS/FOPS rollover protection structure, providing an excellent overview of the work area, comfortable and safe working conditions for the driver. For this purpose, the cabin is mounted on the machine frame on cushions that absorb engine and transmission vibrations and shocks that occur when the dump truck moves along internal quarry roads. The instrument panel is ergonomic, ensuring easy readability of instrument readings and easy accessibility in operating the dump truck. Moreover, in order to create safe conditions The driver's seat is adjustable in five positions, suspended on damping cushions and equipped with seat belts 78 mm wide, and steering column- telescopic design, with the ability to adjust its angle of inclination.
All HD 1500-7 wheels are equipped with wet multi-disc brakes, which provide the highest braking force of any dump truck in its class. This brake design and fully hydraulic control systems ensure low operating costs and high reliability.
Multi-disc wet brakes and fully hydraulic control systems ensure low operating costs and high reliability in operation, since they (the brakes) are completely isolated from dirt, which reduces their wear.
Service brakes and retarders are isolated from other hydraulic systems of the dump truck to ensure their reliability. The parking brake of the dump truck uses a spring attachment, combined with three dry discs mounted as an input race to the differential. Fully hydraulic systems Brake controls eliminate the use of a pneumatic system: no air bleed is required, and problems arising from water condensation from the air, which can lead to contamination, corrosion and freezing, are completely eliminated.
Efficient and smooth braking performance The dump truck is provided with a system of valves for proportional distribution of hydraulic pressure (PPC), which very accurately and in doses determines the amount of hydraulic pressure for each brake unit cars.
On dashboard In the dump truck cabin there is an auxiliary button for activating the brakes. By pressing this button, wet multi-disc brakes are activated on all wheels. Also, thanks to this button, the brakes are automatically activated when the hydraulic fluid pressure drops brake chain below a certain level.
The dashboard of the dump truck provides constant visual control over the technical condition of the main units and components. If a problem occurs or signs of a problem are approaching normal mode their panel works appear in light and digital forms warning signals and information that tells the driver what to do. All malfunctions in the operation of the machine are recorded and stored in coded form for later reading onto a laptop computer of the service department.
The main design feature of the HD 1500-7 is the unusually increased configuration of the dump truck various systems automatic control, blocking, diagnostics and maintaining stable modes of its operation with specified parameters when moving in specific mining conditions of quarries.
In addition to the above-mentioned systems and devices, the dump truck is equipped with an ARSC system - automatic maintenance of a constant speed when the dump truck moves downhill, which allows the driver to set (assign) a fixed speed using a special joystick, focusing only on controlling the movement of the dump truck along quarry ramps. The system allows the driver to set speeds, changing them in increments from ±1 km/h to ±5 km/h, by simply pressing a joystick button located on the dashboard, and ultimately select optimal speed movement of the dump truck downhill.
At the same time, the system constantly monitors the temperature of the oil cooling the retarder, so that when the oil heats up above the permissible temperature, the speed of the dump truck is automatically reduced.
The AISS system is designed for rapid diversion into automatic mode heat from the engine coolant and use of this heat to heat (cool) the dump truck cabin. At the same time, the system ensures engine operation in mode idle move with a crankshaft speed of 1000 rpm at a coolant temperature of 30°C or lower. If the fluid temperature rises above 30°C, the system reduces the engine speed to 650 rpm.
In addition, the dump truck is equipped ASR system for automatic regulation of traction forces developed by the drive wheels. This system supports maximum level traction characteristics by preventing the rear drive wheels from slipping in any direction.
Lubrication of friction pairs and dump truck mechanisms is ensured automatic system Lincoln Autolube.
The HD 1500-7 dump truck is characterized by the following series design features. The front wheel suspension is independent, MacPherson type, mounted on an A-frame installed between each wheel and the main frame of the dump truck.
The increased distance between the front wheels and the main frame of the dump truck increases the steering angle of the wheels. It is clear that the greater the angle of rotation of the wheel, the smaller the turning radius of the dump truck. Thanks to this design of the front suspension, the minimum turning radius of the dump truck is 12.2 m.
Telescopic shock absorbers independent suspension front wheels provide a smooth ride and comfortable handling of the dump truck when driving along quarry roads.
Extended wheelbase, wide track and exceptionally low center of gravity allow the dump truck to develop high operating speeds and greater productivity when transporting quarry cargo.
The large loading area of the body (with a width of 5.70 m and a length of 7.67 m) makes the process of loading a dump truck technologically simple - with minimal spillage of rocks through the sides of the body both during loading and when the loaded dump truck is moving along the roads. The volume of rock placed in the body (with a “cap”) is 78 m3.
Equipping the dump truck transmission with the Skip-shift system allows, when moving a loaded vehicle uphill, to move at an automatically selected speed in a gear corresponding to the steepness of the road rise. As a result, while the dump truck is moving uphill, the number of gear changes is optimized, which ensures smooth operation, reduces cargo spillage and increases driver comfort.
The dump truck is equipped with a flat-bottom body made of high-strength and wear-resistant steel with a hardness of 400 HB, which provides excellent rigidity, large
service life and low operating costs. In addition, the sides and bottom of the body are reinforced with stiffeners. The bottom is made of rolled sheets 19 mm thick, the front wall is made of 12 mm sheets, the sides are made of 9 mm sheets. In winter the body is heated exhaust gases engine, directed into the cavities of the bottom and sides.
When unloading, the dump truck body tilts at an angle of 45° using two 3-stage working cylinders new design, providing damping of dynamic vibrations, smooth and reliable unloading of cargo. In addition, the body frame design reduces the speed of its lowering after unloading in order to reduce the dynamic impact on the truck frame and suspension. The time for raising a loaded body and lowering an empty one is 15 seconds each.
In the tail part of the dump truck frame in the area rear axle reinforced console with lights: side, brake, flashing and reverse, as well as sound signal, which turns on when the dump truck is moving in reverse.
All hydraulic circuits of the dump truck are equipped with large-volume coolers, designed to improve the reliability of components during periods of sudden increases in hydraulic fluid temperature. For the same purpose, each hydraulic circuit, in addition to the main filter, has an additional linear filter (Pu = 3 min), installed in front of the chain control valve.
The dump truck is equipped with a VHMS system - for remote monitoring technical condition vital units and components. Using this system, designers, factory personnel and distributors can obtain a complete set of information about the operation of the dump truck, if necessary.
To produce the HD 1500-7 dump truck at own factories Komatsu manufactures torque converters, transmissions, hydraulic cylinders and electrical components.
The dump truck is produced in an integrated production system ensuring strict adherence to quality standards for production facilities located in America and Japan.
Depending on the geographical location of the customer, the production of machines for him will be located where their transportation will require less cost and time. Since the first Russian customers of the HD 15007 are located in the Far North of Russia, the dump truck is now being adapted to work in climatic conditions-40°С. This Special Order for Russia is located at American production facilities. And this is not the limit, because... It is possible to manufacture a dump truck in an arctic design, i.e. at -50°C. It should be noted that the HD 1500-7 dump truck was initially designed to operate in temperature and climatic conditions down to -30°C.
If necessary, at the request of customers, it can be installed on the machine preheater. This option is necessary for the normal operation of dump trucks in areas where there is no equipment maintenance infrastructure.
Some things can evoke delight and emotion. Wow! Oh! Well, in general! This is how I can convey my feelings when, as part of a press tour to the Mikheevsky Mining and Processing Plant, they offered me a ride and a close look at the huge Komatsu dump truck 730e. The metal content in the ore is low, so efficient work large volumes of processing are required. Operating ore reserves at the deposit reach 400 million tons. One of the largest copper mining and processing plants in Russia was built at the deposit to process up to 18 million tons of copper ore per year. Carry, transport, do not transport! 
Initially, I saw him from a great distance, well, a car and a car, but when we drove up to him in a Kruzak 200, I was overcome. Komatsu 730e - it's huge. At first moment, you don't believe that this is a car. 
You feel like a child next to this giant. 
For comparison. On the right is a standard Japanese pickup truck. 
The car is hybrid. There is both a diesel engine and a wheel motor. 
Technical characteristics: Height: 6.25m Width: 7m Length: 12.83m Engine: 2000 hp Electric motor: 1,884 hp Speed (maximum): 64.5 km/h Load capacity: 183,730 kg. Empty weight: 140,592 kg. Turnaround: 13 meters. In order to get into the cabin, you need to climb a ladder. 
Next you find yourself on the “deck”. It offers a beautiful view of the quarry. 
Passage to the cabin. 
Deck! 
The controls of this giant are the same as on a regular one. passenger car. Steering wheel, two pedals + motion control joystick. Back and forth. There is no box as such. An electric motor is responsible for driving and braking. The cabin is very quiet and cool. The doors are very thick. There is an air conditioning system. 
Go! Loading. 
Everything happens quickly and very smoothly. 
The volume of the excavator bucket is 22 cubic meters. Captures 180 tons in 2-3 minutes. 
You expect the car to rock and shake, but it doesn't. Driving a giant is easier than driving a UAZ with a manual transmission. The main thing is to understand that your base is (ahem) a little longer. A BELAZ passing by looks like a toy. 
The car's throttle response is excellent, whether loaded or empty. The fact that you have 180 tons behind you is not felt at all. I pressed the gas and went. I pressed the brake and stopped. All. There are no special effects or surprises. There is no body roll. Visibility from the cabin is excellent. But you don’t see what’s under the wheels. 
If anything happens, they will always correct you on the radio, and extra people doesn't happen there. Let's go. 
Oh, how cool it is when such cars rush past you at a speed of 50 km/h. =) It takes your breath away and makes your heart skip a beat. The Giant rides quietly. The fifty-liter diesel engine mutters, of course, but everything is within the limits of comfortable sound. The cars operate around the clock, without stopping - only maintenance and driver changes. 
Day and night, winter and summer. The turning radius is 13 meters. The car is quite maneuverable. They drive up, maneuver, unload. Everything is like on regular trucks. 
When reverse gear is engaged, the siren sounds. It is impossible not to notice or not to hear. 
Komatsu 730e. Top view of a loaded dump truck. The rock is sharp and hard and wears the body down to holes in three years. 
More emotions than racing car or the most expensive “luxury” car. Since childhood I dreamed of driving a mining dump truck. And now the dream has come true.

In his latest version Komatsu autonomous mining dump truck completely got rid of the driver's cabin, became unmanned and received new design, which optimizes the distribution of load on the wheels. That is why the machine is built in such a way that there are no concepts of front and rear; the dump truck moves equally efficiently both forward and backward, and it does not need to make turning movements. Komatsu began testing its own (AHS) in a partnership with mining company Rio Tinto in 2008, and the technology has since enabled it to move hundreds of millions of tons of rock from mining quarries in Chile and Australia using autonomous trucks.
Komatsu Haulage - an autonomous dump truck without a driver's cab
The previous version of Komatsu's autonomous mining truck, the 930E, is equipped with remote control, wireless networks, obstacle detection system, autopilot. But it still looks like a regular mining dump truck and comes with a driver's cab. But a new version The dump truck is very different from the 930E model. The new product has a long name "Innovative Autonomous Haulage Vehicle", it has a 2700 hp engine, the length of the dump truck is 15 meters, and the cabin has disappeared, which completely changed the design of the vehicle. Its weight is better distributed across all four steering wheels, improving traction and maneuverability. 
New model Komatsu's autonomous dump truck was unveiled at MINExpo International in Las Vegas this week. It doesn't need a driver, a cab, or rear-view mirrors. The truck moves equally efficiently backwards and forwards, meaning there is no longer the need to make turns, so increased maneuverability, increased productivity and reduced wear on the 8.5m tires. The dump truck can carry 230 metric tons payload and reaches maximum speed 64 km/h.
