物料搬运运输设备上的分iller臂用作中央控制机构。在码垛车和电动行人专用车上，中央控制操纵杆用于提升，降低，转向等。为了安全起见，释放操纵杆会使其回到直立位置。

The Tiller Arm on material handling transportation equipment is used as the central control mechanism. On Pallet Trucks and Electric Powered Pedestrian Trcuks the central control tiller arm is used to lift, lower, steer etc. For safety, release of the tiller arm will cause it to return to the upright position.
