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.
