Rear dump semi-trailer

 The rear dump semi-trailer adopts a combination design of hydraulic lifting system and rear dump cargo box, which is the first choice for medium and long-distance transportation of bulk materials such as sand and gravel, coal, and grain. Its core advantage lies in the ability to flip the cargo box backwards through the hydraulic top rod at the rear of the vehicle, which can achieve a 60 degree angle for unloading, making it particularly suitable for operations in restricted areas such as yards and construction sites. The box is made of high-strength steel and welded together as a whole. An anti sticking lining plate can be optionally installed inside to effectively solve the problem of residual wet and sticky materials. The dual acting hydraulic cylinder system equipped ensures both lifting stability and quick reset. The chassis has been reinforced and can maintain good passability even when fully loaded. This model is easy to operate, and the driver can complete the entire unloading process through the control valve in the cab. A single operation only takes 3-5 minutes, which is more than 10 times more efficient than traditional manual unloading. At the same time, modular design makes maintenance more convenient, and key components are equipped with dust-proof and waterproof protection devices, significantly extending the service life of the equipment.
