The structure of the engine, chassis, and cab of a dump truck is the same as that of a general truck.
High pressure oil enters the lifting hydraulic cylinder through the distribution valve and oil pipe, and there
is a safety guard board in the front of the carriage.
The engine drives the hydraulic pump through a transmission and power take-off device, and the hydraulic
tilting mechanism of the carriage is composed of an oil tank, hydraulic pump, distribution valve, lifting hydraulic
cylinder, control valve, and oil pipe.
The engine drives the hydraulic pump through the transmission and power take-off device, and high-pressure
oil enters the lifting hydraulic cylinder through the distribution valve and oil pipe, pushing the piston rod to tilt
the carriage. Tilting in the future is more common, and by controlling the piston rod movement through the
control system, the carriage can be stopped at any desired tilting position. The carriage is reset using its own
gravity and hydraulic control.
