What are the main types of dump trailers?
The end dump trailer is equipped with a hydraulic system at front, and the rear of the trailer can be opened to unload the cargo.
The working principle of the hydraulic system: The hydraulic oil enters the cylinder through a single valve through a manual booster stalk (hydraulic manual pump). At this time, the hydraulic oil entering the cylinder cannot be backed up due to the single valve, forcing the cylinder rod upward, and Work continues to make the hydraulic oil continue to enter the hydraulic cylinder, so it keeps rising, and when it is going to lower, open the hydraulic valve to return the hydraulic oil to the fuel tank.
The side dump trailer is the box panel on the side of the trailer that can be opened, and then the side unloading is realized by the side hydraulic device.
Structure of side-loading semi-trailer: manual control valve is installed in the easy-to-operate position of the tractor cab; power take-off is installed on the gearbox of the tractor; The car frame is connected to the gear pump; the fuel tank is close to the back of the tractor cab and fastened to the tractor frame; multiple lifting cylinders are reasonably distributed at the bottom of the semi-trailer cabin; a single self-rescue cylinder is arranged at the half The rear of the trailer frame; the multi-way valve is fixed on the semi-trailer web near the self-rescue cylinder. When the dump device is working, the semi-trailer cabin is centered on the hinge point between the cabin and the side of the frame as the center of rotation, and the cabin is tilted by the lifting cylinder supported at the bottom of the cabin. The vehicle is separated from the cargo.
