The semi-trailer dump truck belongs to the category of machines used for the transportation of bulk cargo and characterized by high efficiency. It is indispensable for the transportation of large quantities of sand, gravel and gravel during the construction of roads, repair work and construction. Transport has a tipping platform and the base of a cargo semi-trailer. It is divided into several types according to the maximum degree of inclination of the body part, load capacity, size, design of the tipping mechanism and the time allocated to lowering and raising the platform.
Tipper semi-trailer: description
The hydraulic lift is designed to operate the tipping mechanism. Unloading can be done in two directions, while this process can be controlled from the cab. The capacity of the dump truck is one of its positive aspects, but because of this, it should be used simultaneously with the tractor, which has a powerful motor. The semi-trailer is complemented by four-wheel drive, anti-lock braking system, a chassis with three or four axles and high-quality mechanisms necessary to prevent unintentional lowering of the body. Often they are a bar fixed with hinges. The bottom of the body should have a smooth and even surface to ensure free unloading of transported materials. The period of operation of the semi-trailer depends on the quality of the body, in particular on the wear resistance and strength of the materials used for manufacturing.
Benefits
Gander semitrailer is widely used due to its ease of use. It provides efficient transportation and unloading of materials without special time costs. Also, with it, significant economic benefits are achieved by increasing the productivity of the work performed. Compared to a dump truck with a similar volume, it is able to transport a larger amount of cargo, and its purchase will cost much cheaper.
The tipper semi-trailer, the photo of which is presented above, has many advantages, among which it is worth highlighting the following:
- significant margin of safety;
- reliable nodes;
- the design was created specifically for Russian conditions;
- there is the possibility of processing anti-freezing composition;
- the ability to choose a model, depending on the intended type of work.
Materials
The tipper semi-trailer can have rear and side loading. The latter variety has become most widespread in agriculture, where unloading inside hangars and storage facilities is required. But the technique with rear unloading is considered more effective due to the lower mass, increased body volume and simple design.
For the manufacture of semi-trailers, aluminum and steel are used, each material is selected depending on the purpose of the transport. Heavy steel options are used for the delivery of solid loads with a large mass, and aluminum, lightweight - for bulk, but light. In accordance with the purpose, other technical properties are selected, 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 suspension and thinner walls.
Body shape and volume
The carrying capacity of a vehicle directly depends on the number of axles and the equipment with a reinforced frame. The four-axle semitrailer-dump truck is distinguished by the highest carrying capacity; it can carry simultaneously a weight of up to 45 tons.
The body can have a square and semicircular shape. The first option is more universal, it provides transportation not only of bulk materials, but also of brick and tile. The semicircular dump semitrailer is not without advantages, these include quick unloading due to the boards, devoid of welds, and the shape of the compartment for transporting materials, relatively small weight, and stability during unloading.
The volume of the body part is selected in accordance with the purpose of the transport. The largest volume is needed for transportation of heavy rocks, while coal and bulk cargo can be transported by dumping equipment with a volume of 35 cubic meters. m
