工业车辆的构造原理。车轮支撑和悬臂式工业车辆之间有区别。轮式工业车辆都是所有的托盘车，它们通过其升降单元将运输单元抬离地面以进行水平运输。平台车（也称为轮式堆高机）配有桅杆。他们需要额外的稳定器（装载轮臂），这些稳定器可以安装在装载单元下方或平台下方，也可以作为宽轨堆垛机在装载装置周围行驶。在这种情况下，它们就像悬臂式叉车一样配备了锻钢叉。

        Construction principle of industrial trucks. Distinctions are made between wheel-supported and cantilevered industrial trucks. Wheel-supported industrial trucks are all pallet trucks which lift the transport unit clear of the ground for horizontal transport by means of their lift unit. Platform trucks, also called wheel-supported stackers, are equipped with a mast. They need additional stabilisers (load wheel arms) that are either mounted below the load-carrying unit or a platform or drive around the loading device as wide-track stackers. In that case they are equipped with forged steel forks, just like the cantilevered forklift trucks.
