HOWO 6x4 Dump Truck

HOWO 6x4 dump truck's carriage is a rectangular and U-shaped all-metal welded structure. It is made of high-quality steel plates and pressed and welded. It has sufficient rigidity and strength. Users can also make their own special requirements for customization. The sub-frame is the basic part for installing the lifting mechanism and the car body, and it is also a fixed reinforcement connected to the chassis of the car. Different types of dump trucks are pressed into grooves with high-quality alloy steel plates. The longitudinal beams and cross beams of the cross section are welded, and the rear end of the sub-frame adopts a triangular structure that increases the distance between the carriage supports to ensure the stability of the carriage during the driving or lifting operation of the vehicle. The sub-frame is fixed and integrated with the chassis of the car, which also strengthens the rigidity and strength of the chassis beam of the truck,a safety support bar is installed at the rear of the sub-frame, which can be supported during vehicle maintenance to prevent the car from falling down by itself.

HOWO 6x4 dump truck's dumping mechanism is divided into two types: front straight multi-section hydraulic cylinder and front straight top dumping mechanism, and a triangular top arm floating link enlarged combination type. Structure of top dumping mechanism: The basic components are composed of multi-section telescopic hydraulic cylinders, high-pressure oil pipes, oil tanks, oil pumps, distribution valves, and so on. The high-pressure oil is output by the oil pump, and the oil cylinder pushes the car body up to realize the dumping of material under the effect of the high-pressure oil. 2. The structure of the combined lifting and dumping mechanism of the floating link and the enlarged triangular arm under the abdominal roof is mainly composed of a triangular arm, a tie rod, a single-acting piston hydraulic cylinder, a high-pressure oil pipe, an oil pump (with a distribution valve), and a fuel tank (optionally selected according to the model). ) And other components, through the work of the oil tank to achieve the car loading and unloading.

HOWO 6x4 dump truck's power of the hydraulic system is taken from the chassis gearbox of the car, and the gear oil pump is driven by the power output of the power take-off; the manual air valve and the distribution valve are operated to form a control system. The flow of hydraulic oil from the high-pressure oil pump realizes the lifting of the hydraulic cylinder.

The vehicle identification code is engraved on the dump truck product label. The operation of our products is different due to different chassis and lifting mechanisms. Users should read this manual carefully and choose the operation mode according to their own models.
