Abstract
A method is provided for controlling a vehicle lifting device, having at least two, preferably moveable, lifting columns (1-4), which are controlled wirelessly. When a switch is activated for raising or lowering the lifting device, a corresponding signal is transmitted wirelessly to the lifting columns (1-4) and additional signals, which are representative of the individual lifting movements, are transmitted to a control device (5). In the case of unacceptably high movement differences between individual lifting columns, the normal operation is stopped. Here, it is essential that for monitoring the wireless signal transmission, the control device (5) exchanges control signals with the lifting columns (1-4) continuously, and the reception of these control signals is monitored at least in one direction.
