Semitrailer-dump truck belongs to the category of machines,used for transportation of bulk cargo and characterized by high efficiency. It is indispensable when transporting a large amount of sand, gravel and gravel during road construction, repair work and construction. Transport has a tilting platform and a cargo semi-trailer base. It is divided into several types according to the maximum degree of inclination of the body part, load-carrying capacity, dimensions, design of the overturning mechanism and the time taken to lower and raise the platform.
Hydraulic lifter is designed foroperation of the tilting mechanism. The unloading can be carried out in two directions, while the control of this process can be carried out from the cabin. The payload of a dump truck is one of its positive aspects, but because of this it must be used simultaneously with a tractor that has a powerful motor. The semi-trailer is supplemented with a full drive, anti-lock system, a chassis with three or four bridges and high-quality mechanisms necessary to prevent unintentional descent of the body. Often they are a bar fixed with hinges. The bottom of the body part should have a smooth and even surface to ensure a free discharge of the transported materials. The period of operation of the semitrailer depends on the quality of the body, in particular the wear resistance and strength of the materials used for manufacturing.
Semitrailer-dumper on gander has acquired extensiveThe distribution is due to the ease of operation. It provides efficient transportation and unloading of materials without much time. It also achieves significant economic benefits by increasing the productivity of the work. Compared with a truck with a similar capacity, it is able to transport more cargo, and its purchase will be much cheaper.
Semitrailer dump truck, the photo of which is presented above, has many advantages, among which is the following:
Semitrailer dump truck can have rear and sidedownload. The latter variety has become most widespread in agriculture, where unloading is required inside hangars and storage facilities. But more effective is the technique with the rear unloading due to the smaller mass, the increased volume of the body part and the simple design.
For the manufacture of semi-trailersaluminum and steel, each material is selected depending on the purpose of transport. Steel heavy variants are used for the delivery of solid cargo, having a large mass, and aluminum, lightweight - for bulky, but light. In accordance with the purpose selected and other technical properties, for example, the type of suspension and the thickness of the body. Steel models have a spring suspension and walls with a thickness of 6 mm, while aluminum models have a pneumatic version of the suspension and thinner walls.
The carrying capacity of transport depends onnumber of axles and a reinforced frame. The four-axle semitrailer-tipper differs the greatest load-carrying capacity, it can carry simultaneously weight in limits of 45 tons.
The body can have a square and semi-circular shape.More universal is the first option, it provides transportation of not only loose materials, but also bricks and tiles. Semi-circular semi-trailer-dumper is not without advantages, among them there are fast unloading due to the boards, devoid of welded seams and the shape of the compartment for transportation of materials, relatively small mass, and also stability during unloading.
The volume of the body part is selected in accordance withthe purpose of transport. The greatest volume is necessary for transportation of heavy rocks, while transportation of coal and bulk cargo can be made by dump trucks with a volume of 35 cubic meters. m.
