What are the maintenance skills of dump trucks?

Dump truck is a vehicle that unloads goods by hydraulic or mechanical lifting, which needs frequent maintenance. Some car owners don't know how to maintain their own vehicles after buying dump trucks, which leads to the reduction of the service life and performance of dump trucks. The new dump truck or the overhauled car must be put into trial operation, so that the lifting process of the car is stable and there is no movement. When the trailer is used directly, the lubricating oil should be selected correctly in all parts according to the regulations, which greatly saves the unloading time and labor, and the lifting mechanism should change the oil strictly on schedule. According to the rated load, it is forbidden to overload. Effective maintenance skills of dump trucks.

Operating specification: 1. Do not suddenly push the lifting handle to the "down" position during full lifting. If this kind of operation error occurs, the carriage will suddenly rush down, which will bring great impact to the frame and even cause an accident. Therefore, the above operations should be avoided as much as possible. If there are special circumstances, you must also operate carefully, try to slow down the landing speed, and you must not suddenly drop the car to the end. 2. Don't use the car-slam on the brakes to unload the goods. Due to the large inertia force (generally 5~20 times of the rated lifting force), it is easy to cause permanent deformation of the frame, welding between the carriage and the subframe, burning out the oil pump or damaging the sealing ring and hydraulic cylinder. , will reduce the service life of vehicles, and even lead to rollover accidents. Therefore, it is forbidden to drive a dump truck during lifting. 3. Before driving, the dump truck must be separated from the power take-off. If this kind of operation error occurs, the lifting oil pump will run in a "small cycle" state at high speed for a long time because the power take-off is in the "engaged" position when the dump truck is driving. As a result, the oil temperature of hydraulic oil rises rapidly, which is easy to damage the oil seal of the oil pump and even causes the phenomenon of "burning to death" of the oil pump; More seriously, the operation of the oil pump means that the hydraulic system has a power source, and it is easy for the car to automatically rise during driving. 4. When driving, the power take-off should not be in the "ON" position. If it is in the "on" state (red light is on), the oil pump will continue to rotate, and the hydraulic system will have a power source, which will automatically lift the carriage due to misoperation on the pneumatic control valve; At this time, even if the pneumatic distribution valve is in the "downward" position, oil will enter the oil pump, thus burning the oil pump.
