Abstract
An electrohydraulic tilting device for a vehicle with a tilting cab has a pump, an electric pump drive motor connected by way of an electrical connecting line to a source for electrical energy, and a hydraulic piston/cylinder unit connected to the pump. The piston/cylinder unit is designed for exerting a force which is capable of tilting the cab forward and back. An overcurrent protection device is provided which is designed for automatic interruption and subsequently maintaining the interruption of the electrical power line of the pump motor when the electrical power taken up by the pump motor for a predetermined period exceeds a first threshold value which is higher than the maximum electrical power required during normal tilting of the cab. The overcurrent protection device is provided with manual reset means for ending the interruption of the power line.
