大功率叉车由三相电流驱动。在这些车辆中，电池中存储的直流电（DC）通过三相变频器转换为三相AC。三相技术的优势是与柴油和LPGas叉车相比具有较高的行驶和提升速度以及加速度和物料周转值。

        High-power lift truck driven by three-phase current. In these trucks the direct current (DC) stored in the battery is converted to three-phase AC by a three-phase frequency inverter. Advantages of three-phase technology are high travel and lifting speeds as well as acceleration and material turnaround values comparable to diesel and LPGas lift trucks.
