物体的质量，以千克或吨为单位。工业车辆的自重（也称为服务重量）是通过称重确定的，必须在铭牌上列为技术数据。确定工业车辆的重量时不考虑驾驶员的有效载荷和重量。对于带电池驱动的叉车，电池重量是稳定所需的自重的一部分。由于电池重量取决于电池容量，因此必须为容量较小的电池补偿重量。

         Mass of a body in kg or t. The dead weight, also known as service weight, of industrial trucks is determined by weighing and must be in listed as technical data on the identification plate. The weight of an industrial truck is determined without payload and weight of the driver. For lift trucks with battery-electric drive the battery weight is part of the dead weight required for stability. Since the battery weight depends on the battery capacity, the weight must possibly be compensated for batteries with lower capacity.
