大剪升降机用动力单元

此液压动力单元采用零泄漏双向止回阀实现两条油路的完全隔离，使用两条油路的上升和下降动作互不干涉，是多缸单独升降系统的理想动力源。该系列动力单元广泛用于子母台式（大剪）升降机，采用直流电机可用于卡车尾板

Equipped with the zero leakage bi-directional solenold valves,this power unitfulfils the complete separation of the two independent circuits,which are respectively for the main platform and subordinate platform of the double scissors lift.By increasing the number of the solenoid vavles,it is easy to get more independent circuits,which are used to control the corresponding cylinders.
