自卸拖车动力单元2 TIPPER TRAILER POWER UNIT2
简介General Description
此液压动力单元由高齿轮油泵、直流电机、多用集成块、
液压阀、油箱等零部件有机组合为一体。系典型的动力上升、
重力下降液压回路。启动电机实现上升，打开电磁卸荷阀实现
下降，下降速度由内置平平衡阀自动控制。广泛应用于车辆机械
、园林机械等。
Equiped with a high pressure gear pump, DC motor,a multi-functional
manifold,valvesand a tank。This power unit has a power up gravity
down circuit。Start the motor to lift the machine and the lowing
movement is activated by the solenoid valve with the lowering
speed controlled by the pressure compensated flow control valve.
It is widely used in tipper trailer,fork lift and scissors lift.
