How do you prevent the dump truck from tilting when unloading?
When driving, the force taking device must not be in the "on" position.If in the "on" state (red light), the oil pump will continue to rotate, the hydraulic system has such power, because it will be in the gas control valve on the misoperation caused by car automatic lift; pneumatic distribution valve at this time even in the "down" position, the oil to enter the pump, it will make the oil pump burn.
After unloading the dump truck, it is necessary to disengage the force taking device before driving.In the event of this error, the dump truck is running at a "joint" position, and the pump is operated at a high speed without load for a long time under the condition of "small circulation". In the hydraulic oil temperature rises very fast, easy to damage the pump oil pump, or "burn" phenomenon; more serious is the pump operation means that the hydraulic system has a power source, automatic car accident rises appear easily in the process of traffic.
Don't use the heavy lifting car to slam the brakes and unload the cargo.Due to fierce car large inertial force (usually 5~20 times the rated lift), extremely easy to cause permanent deformation, and pay for the carriage frame frame welding, burning oil seals, damage or destruction of hydraulic cylinder damage, reduce the service life of the vehicle, there will be serious car accident. Therefore, the general dump truck is forbidden to lift when driving.
Do not push the lift handle to the downward position midway during full load lifting".If this error occurs, the car suddenly rushed down, it will bring great impact on the frame, and even accidents. Therefore, the operation should be avoided as far as possible. If there is a special situation, we must also be careful to operate, and try to slow down the speed of landing. We must not stop the car from falling to the end.
