Platform and the tank

Platform. A distinctive feature of the rolling stock is that it has no roof and walls, instead of which have low pivoting boards. The main type of platform is tetraaxial payload 66 tonnes with metal sides, made of sheet metal formed section thickness of 3 mm. Flooring is made of planks of 55 m on the side rail frame locking device, holder loops boards, staples forest stands, uvyazochnye ring, and on the end beams brackets end boards.

The park has a large number of specialized platforms. Four-platform capacity 60 tons with increased length of the frame are designed to carry large containers. On this platform, you can carry six containers with a gross mass of 10 tons, or three to 20 tons, 30 tons, or one and one 20 tons These platforms do not have boards and flooring. To secure containers on the frame has stops (eyebolts).

For transportation of cars are bunk platform capacity of 20 tons with a long frame 20.8 m cars are in two rows on each level - all on a platform loaded 17 cars.

Four-axle load capacity of 90 tonnes platform designed for the transport of hot pig iron on Internal paths.

A variety of platforms are traisportery. They are especially designed and intended for the transport of the most bulky and heavy loads: transformers and large power turbine stator, bridge trusses, etc.

The main difference from conventional conveyor platform is part of the lower average loading frame, adapted for placement and securing cargo. There are three main types of conveyors: platform, kolodtseobraznye and articulated.

Platform-type transporters have a lower loading platform through the use of a curved main beam. In conveyors kolodtseobraznogo type main beam is composed of two I-section beams bokovyx interconnected at the bottom in the middle of the supporting cross beams. The load on these transporters located between the side beams on the removable cross members, which are as close to the top level of the rail heads.

Articulated type consist of two parts of the console, made in the form of metal trusses. Both of the console, when combined, form the main beam, which relies on the trolley through kontsevye frame. The load on the conveyor is mounted between the console part and secured by means of springs and rollers. During the movement of the cargo takes over the load acting on the rolling stock.

 

Tank. Depending on the type of cargo tanks, boilers have different constructions. In this connection distinguish tanks that carry oil, light oil, high viscosity lubricants and fuel oil, are heated to ensure their normal discharge and special purpose - to carry various acids, liquefied gases, chemicals, cement, and food products.

The most widely used four-axle tank capacity 60 tons in recent years, are also built and eight tanks frameless design capacity of 120 tons, with two boot hood and two drain device.

In previous years building tanks capacity was 50 tons and bottom discharge devices shall be placed only on those that are intended for the transport of heavy petroleum products (oil, fuel oil), as well as having high ignition temperature (kerosene, diesel, fuel oil). Tanks for transport of light flammable goods (gasoline, naphtha, alcohol) lower drain devices do not have and upload them is performed using special settings through the top cap.

At each boiler tank depending on the size of the calibration number is applied in the form of metal stamped numbers, reinforced by welding.

To determine the amount of cargo that is in the tank, measure the height of the loading special rail (metroshtokom), and then the tables, knowing the level of loading and type of tank calibration, determine the volume of cargo. Multiplying the density of the cargo volume to receive its weight without weighing in the balance tank.

Park special tanks for the transportation of a particular cargo is very diverse and has more than thirty types.

A four tank capacity of 31.2 tons for transportation of milk boiler is made of aluminum and consists of three sections, each of 10 cubic meters. In tanks provided the right conditions for transportation of milk at ambient temperatures from +30 to-40C by a powerful insulation layer on the boiler. Insulation thickness of 300 mm made of mipory wrapped perfolem steel cover and protected from mechanical damage.

In tanks for acid copper has a volume of almost two times less than that of oil and gasoline, and made of materials resistant to acids: of stainless steel for the transport of weak nitric acid, aluminum - strong nitric acid, from a two-layer steel (inner layer stainless steel and the outer carbon) - for improved sulfuric acid. Boilers, tanks for hydrochloric acid welded from sheets of carbon steel and then covered in a protective layer of rubber 5mm way gumming.

Tanks for transport of cement have the usual boiler, like tanks for petroleum products, but additionally equipped with devices for loading and aeropnevmovygruzki.

Small amounts are also tanks for liquefied gases (propane, ammonia, chlorine, etc.), phenol, ammonia, ethyl fluid, acetaldehyde, alcohol, molasses, molten sulfur, yellow phosphorus, sulphanol paste, liquid pitch and other goods.
