辅助升降机(Supplementary Lift)
辅助提升可以通过附加或辅助桅杆来实现。例如，订单拣选升降机和垂直订单拣选机可以配备辅助升降机。辅助升降机使操作员可以将托盘放置在最符合人体工程学/最佳高度的位置，以进行订单分拣。为了拣选起重车，可以通过辅助举升机构执行托盘堆放和取回操作的精确定位，而不必移动驾驶室。
英文介绍
Supplementary lift can be implemented by an additional or secondary mast. For example, order picking lift trucks and vertical order pickers can be equipped with supplementary lift. The supplementary lift allows the operator to position the pallet at the most ergonomically/optimum height for order picking duties. In order picking lift trucks the fine positioning for the stacking and retrieving operation of pallets can be executed by the supplementary lift mechanism without having to move the driver's cabin.
