Rear Dump

The rear-tipping dump semi-trailer is fully equipped with a complete hydraulic drive system, featuring a dedicated hydraulic unit and hydraulic pump as the power source. During operation, the hydraulic pump continuously builds pressure and steadily delivers high-pressure hydraulic oil into the multi-stage telescopic hydraulic cylinder.

 

Driven by oil pressure, the piston extends step by step. Leveraging the telescopic structure of the multi-stage cylinder, the front section of the cargo box is lifted steadily and gradually. With a scientifically designed tilting angle and the gravitational potential energy of materials, bulk cargo such as sand, gravel, muck, ore and grain slides smoothly out from the rear of the carriage.

 

The entire unloading process requires no manual digging or handling, which greatly reduces labor costs, simplifies the unloading procedure, and effectively improves the overall transportation and operation efficiency.

The hydraulic system serves as the power core of the rear-discharge vehicle. Its core working principle lies in efficient energy conversion, which accurately converts the mechanical energy output by the tractor engine into powerful and stable hydraulic energy. The entire hydraulic circuit features excellent airtightness and pressure resistance, enabling continuous high-pressure power transmission to the hydraulic oil cylinders through oil pipelines. It generates tremendous thrust via hydraulic pressure to easily bear the weight of fully loaded cargo boxes and materials, achieving stable lifting operations.

 

With a compact structural design, strong load capacity and low failure rate, this power system adapts to harsh working conditions such as high-intensity construction sites, mines and infrastructure projects. Through stable power output, it realizes fast automatic unloading of large quantities of bulk materials and meets the demands of high-frequency and continuous vehicle operation.

Equipped with professional control valves and distribution valve assemblies, the hydraulic system allows operators to precisely adjust the oil circuit direction and oil pressure via manual handles. It flexibly controls the lifting, holding and lowering movements of the cargo box, enabling the box to be securely locked at any inclined angle.It supports segmented and controllable slow unloading to adapt to narrow sites, confined spaces and wet sticky materials, preventing material accumulation, waste and potential safety hazards caused by rapid dumping.After unloading, the pressure relief valve opens to regulate the oil circuit, allowing hydraulic oil to flow back to the tank in an orderly manner. The cargo box descends slowly and evenly under its own weight with excellent cushioning performance, avoiding rigid impact and protecting the vehicle structure and hydraulic components for stable and reliable resetting.

 

 

 

 

 

Infrastructure and Earthwork Engineering

As the core and high-frequency application scenario, it mainly transports infrastructure materials such as sand, soil, crushed stone and asphalt, and undertakes site leveling and earthwork clearance. The rear-tipping structure delivers high unloading stability and prevents carriage damage when hauling large stones, offering superior adaptability to various working conditions.

Mining and Quarry Operations

It adapts to the harsh and complex mining environments. Heavy-duty and articulated rear-dump vehicles are applied for raw ore transportation and waste rock disposal. With a stable center of gravity, the vehicle is suitable for driving on rugged slopes. The cargo box is made of high-strength wear-resistant steel, featuring excellent impact resistance and abrasion resistance to meet high-intensity mining operations.

Large-scale Road and Water Conservancy Projects

Widely used in the filling construction of expressways, reservoirs and dams, it enables fixed-point precise unloading to facilitate rapid paving and compaction by supporting machinery. Meanwhile, compact rear-dump models feature flexible size and are competent for narrow-space construction such as tunnel mucking.

Agricultural and Industrial Bulk Logistics

In agriculture, it realizes large-scale grain transportation connecting farms and grain depots. In industrial scenarios, it serves power plants and steel mills to efficiently transport and unload bulk materials including coal and coke, covering agricultural harvest transportation and short-distance material handling inside factories.
