Electrohydraulic tilting device for a vehicle with a tilting cab, comprising a pump (20), an electric pump drive motor (21) for driving the pump, which pump drive motor is connected by way of an electrical connecting line (22) to a source (23) for electrical energy, and a hydraulic piston/cylinder unit (10) connected to the pump, one end (13) of which unit is connected to the chassis, and the other end (16) is connected to the cab. The piston/cylinder unit is designed for exerting a force which is capable of tilting the cab forward. An overcurrent protection device (27) is also provided, designed for automatic interruption - and subsequently maintaining the interruption - of the electrical power line (22) of the pump motor when the electrical power taken up by the operating pump motor for a predetermined period exceeds a first threshold value which is higher than the maximum electrical power required during tilting of the cab. The overcurrent protection device is provided with reset means (28) for ending the interruption of the power line which reset means must be operated by a person. <IMAGE> |
