登车桥动力单元厂家/批发/供应商

简介General Description                   

此液压动力单元**为登车桥设计，由高齿轮油泵、直流电机、多用集成块、各式液压阀、油箱等零部件有机组合为一体。主甲板上升到位后，唇板自动上升，主甲板和唇板的下降由电磁阀实现，主甲板和唇板的下降速度由节流阀调节，使下降速度在**的范围内。

This power unit is desig** exclusively for the dock leveler,consisting of high pressure gear pump, DC motor, multi-functional manifold,va**es and tank.etc.After the main platform is fuily lifted, lip rises automatically.The both lowering movements are activated by the solenoid va**es with speed adusted by the throttles.
