Preliminary understanding of dump semi trailer

The rear dump semi-trailer consists of a trailer chassis, a hydraulic lifting mechanism, a force fetching device and a cargo compartment. Dump semi trailer is made of manganese plate welding, long service time, good toughness. In civil engineering, often with excavators, loaders, belt conveyor and other joint operations, constitute a loading, transportation, unloading production line, loading and unloading of earthwork, sand, loose materials transportation.

Dump trailer compartment is divided into backward tipping and lateral tipping, through the control system to control the piston rod movement, backward tipping is more common, push the piston rod to make the compartment tipping, a few two-way tipping.

The rear dump semi trailer suspension adopts non-independent steel plate stamping rigid suspension (optional air suspension) composed of tandem leaf spring and suspension support, reasonable structure, with strong stiffness and strength, used to support the load to slow the impact. Widely used, has become a medium and long-distance vehicle models. It is mainly suitable for medium and long distance transportation of heavy and bulk goods.

Rear dump semi trailer can be divided into two categories according to the use: one is the heavy and super heavy dump trailer used for off-road transportation, mainly undertake large-scale mining, engineering and other transportation tasks, usually used with excavators. The other kind of light, medium and ordinary dump trailers for road transportation mainly undertake the transportation of loose goods such as sand, stone, soil and coal, which are usually used together with loaders.

Advantages of SUNSKY's dump trailer

Because the loading compartment of the dump semi trailer can automatically tip over a certain Angle to unload materials, it greatly saves unloading time and labor, shorters transportation cycle, improves production efficiency, reduces transportation cost, and marks the loading volume. It can effectively improve the efficiency of loading and unloading to transport loose bulk goods.

The dump trailer has high strength, strong lifting force, good stiffness, good toughness, strong bearing capacity and no permanent deformation. The container has two kinds: dustpan and rectangle. The main parts are processed by advanced equipment, and the longitudinal beam is made by automatic submerged arc welding. The assembly machine is used for accurate assembly of wheel shaft and steel plate spring.

The frame design of the dump trailer is reasonable and the process is good. The box body is made of cold-rolled corrugated steel plate with high strength and no skeleton structure. The box body height is varied. The dump trailer has large volume and good airtight performance, which can prevent the pollution of goods and realize the efficient, economic, safe and environmental protection of cargo transportation. It has been highly praised by customers once it is used. Through the hydraulic system to drive the back of the box to quickly unload grain, less manual interference, not limited by the fixed unloading point, very convenient.

It is suitable for the transportation of coal, ore, construction materials and other bulk granular goods, which can effectively improve the efficiency of loading and unloading and transportation.

Tips on selection of dump trailer

Dump trailer is a common semi trailer in our life, semi trailer will generally load some weight items, so the selection of semi trailer is very important

1. Transportation of large items must choose bucket compartment.

2. When the length of the carriage is greater than 5.4m, special attention should be paid to the height of the centre of gravity and lifting stability of the carriage.

3. Can not use coal transport vehicles to transport earth and stone. The height of the compartment of the general coal transport vehicle is 1.6~1.9 meters, and the length design is considered according to the lightweight goods (the specific gravity is less than 1.2). When used to transport earth and stones, there may be the problem of poor lifting stability, which may cause lifting and overturned accidents in serious cases.

4. Do not use the bucket carriage to transport silt, clay and other viscous goods, the structure of the bucket carriage makes the viscous goods more difficult to unload.

5. When selecting the type of dump trailer for transporting iron ore powder, we should declare with the manufacturer. It is best to choose the transport truck for iron ore powder.

6. When used for paving asphalt transportation, the lifting mechanism requires a slow drop device.

7. In addition to looking at the product, we should also understand the equipment capacity of the manufacturer, the design of the dump truck, whether the process equipment is mature, after-sales service commitment, whether the accessories can be bought, etc.

SUNSKY's dump trailer is mainly sold in the West African market. Now we have certain experience, and we have accumulated some customers, making better preparations for our market expansion.
