可以在过道的地板上安装导丝，以便为叉车提供转向指导。它用于自动（无人驾驶）操作-或在没有驾驶员介入的情况下引导起重车通过过道。低压电源被馈入导线，产生电磁场。叉车通过天线准确地跟随该场。

        A Guide Wire can be installed in the floor of the aisles to allow steering guidance for fork lift trucks. It is used in automatic (driverless) operations - or guides the lift truck through the aisle without driver involvement. Low voltage power is fed into the guide wire which creates an electro-magnetic field. The lift trucks, via the antennas follow this field exactly.
