四路堆高车是由电池驱动的叉车，具有将方向盘和装载轮旋转90度的内置容量。因此，叉车可以向前和向后行驶，也可以向两侧行驶。通常，这些车辆在任一行驶方向上都具有完全转向功能，并允许在狭窄的过道中运输长货物。

       Four-Way stacker trucks are battery powered forklift trucks with a built-in capacity of rotating the steering wheel(s) and load wheels by 90 degrees. The truck therefore can travel forward and backward as well as travel to both sides. Usually these trucks feature full steering in either travel direction and allow the transport of long loads in narrow aisles.
