The invention provides an aerial work platform with connecting rod damping. The lifting device is provided with a connecting rod assembly supported by the chassis, a work platform supported by the connecting rod assembly and a hydraulic system. The hydraulic system has a lift cylinder that moves the link assembly between a retracted position and an extended position, and a damping cylinder that increases the stiffness of a pair of links positioned between a distal end of the lift cylinder and the work platform. When the link assembly extends, the lift cylinder receives pressure from the hydraulic system at a first pressure and the damping cylinder receives fluid from the hydraulic system at a second pressure, the second pressure being lower than the first pressure.
本发明提供了一种具有连杆阻尼的高空作业平台。升降装置具有由底盘支撑的连杆组件、由连杆组件支撑的作业平台以及液压系统。液压系统具有使连杆组件在缩回位置与延伸位置之间移动的升降缸,以及增加定位在升降缸的远端部与作业平台之间的连杆对的刚度的阻尼缸。当连杆组件延伸时,升降缸在第一压力下从液压系统接收压力,并且阻尼缸在第二压力下从液压系统接收流体,第二压力低于第一压力。
