Lifting system and method for controlling the lifting system and control system for the lifting system

A method for controlling a lifting system comprising a plurality of lifting apparatuses, each of which has a load-bearing means which is movable up and down, the method comprising:

• activating a control system configured to actuate the plurality of lifting apparatuses, wherein the control system consists includes a control device and a plurality of control units arranged separately therefrom and one on each lifting apparatus,
• the control device and the control units each have a transceiver by means of which control signals are transmitted and received wirelessly, wherein
• the control device and the control units each have data interfaces by means of which at least one presence signal is transmitted between the control device and a respective control unit, and
• the control device is positioned within a signal cone of the data interface of the respective control unit, and
• the respective control unit releases the actuation of the lifting apparatus upon receipt of the presence signal and the control signal from the control device within a time window.

A lifting system for lifting and lowering a vehicle, the lifting system comprising:

• a plurality of lifting apparatuses surrounding the vehicle, each lifting apparatus configured for actuation by a control system, the control system comprising:
• a control device positioned separately from the vehicle and the plurality of lifting apparatuses;
• a plurality of control units, each control unit provided on a respective lifting apparatus and configured for actuating a wheel gripper of the respective lifting apparatus, the control device configured to transmit a control signal and thereby control operation of the plurality of control units, wherein:
• the control device is positioned separately from the control units, and
• each control unit and the control device include a transceiver configured for a wireless transmission and/or receipt of the control signal and/or a presence signal that differs from the control signal, wherein
• a data interface for the wireless transmission of the presence signal is provided on each control unit and on the control device, and
• the data interface on the control device is configured to produce a signal cone that is positioned opposite from the wheel gripper, wherein:
• the control device is aligned with the data interface of the control device and oriented towards the transceiver of one or more control units;
• and
• the control device is positioned within the signal cone of the data interface of one or more control units, wherein positioning of the control device within the signal cone of the data interface of one or more control units permits an operator holding the control device to be outside of the vehicle;
• and
• each control unit is configured to enable actuation of the wheel gripper of a respective lifting apparatus upon simultaneous receipt of the presence signal via the data interface of the control device and the control signal via the transceiver of the control device.
