    Abstract: A trailer provided with a manoeuvring device. The manoeuvring device has a pivoting frame that can be moved with respect to the chassis of a trailer, such as a caravan, and is provided at the end with a roller driven by an electric motor. This roller does not engage on one of the wheels but is itself able to function as a wheel. Lifting of the chassis of the trailer is achieved with the aid of the pivoting frame, as a result of which the existing wheels at least partially lose contact with the ground surface.

    Abstract translation: 配有操纵装置的拖车。 操纵装置具有可相对于诸如大篷车的拖车的底盘移动的枢转框架,并且在末端设置有由电动机驱动的辊。 该滚轮不接合在其中一个车轮上,但本身能够用作车轮。 通过枢转框架来实现拖车底盘的提升,由此现有的车轮至少部分地失去与地面的接触。
