After the dump truck has finished unloading the cargo, the power take-off must be disengaged before it can be driven.
If this operation error occurs, when the dump truck is driving, because the power take-off is in the "engagement" position, the oil lift pump will run at high speed and no load for a long time under the "small cycle" state. As a result, the oil temperature of the hydraulic oil rises quickly, which can easily cause damage to the oil pump oil seal, and even cause the oil pump to "burn out." Accident.
