无人驾驶工业车辆，具有搬运和运输一个或多个负载单元的能力。用运输车运输装载单元也称为“背负式”运输。运货车辆不具备地面接送能力，并且需要定义的“机械”接口来进行负载转移。该接口可以实现为要在其下被驱动的辊式输送机，链式输送机或栈桥。因此，搬运车配备有连续输送机，伸缩叉或升降台。

          Driverless industrial truck with the ability to carry and transport one or more load units. The transport of load units with carrier trucks is also called "piggyback" transport. Carrier trucks are not capable of ground pick-up and require a defined "mechanical" interface for load transfer. The interface can be implemented as roller conveyors, chain conveyors, or trestles to be driven under. The carrier trucks are accordingly equipped with continuous conveyors, telescopic forks, or lifting tables.
