Abstract

The present invention relates to a radio remote control for controlling one or more functions of a crane, preferably of a mobile crane, wherein the radio remote control comprises a hand-held transmitter, whose hardware components are not adapted to the type or configuration of the crane and thus are identical for a plurality of cranes differing in type or configuration, and which is programmable for the purpose of adaptation to the type or configuration of the crane whose function or functions should be controlled by means of the hand-held transmitter.

Claims

1. A radio remote control for controlling one or more functions of a crane, preferably of a mobile crane, wherein the radio remote control comprises a hand-held transmitter, whose hardware components are not adapted to the type or configuration of the crane and thus are identical for a plurality of cranes differing in type or configuration, and which is programmable for the purpose of adaptation to the type or configuration of the crane whose function or functions should be controlled by the hand-held transmitter.

2. The radio remote control according to claim 1, wherein the hand-held transmitter has a graphics display.

3. The radio remote control according to claim 1, wherein the hand-held transmitter includes one or more function keys which include of at least two actuating elements, one of which is an on/off key and another one of which is an analogue key responding to the actuating pressure.

4. The radio remote control according to claim 1, wherein the hand-held transmitter includes an enabling key and/or an emergency stop button.

5. The radio remote control according to claim 1, wherein the hand-held transmitter has sending or transmitting means which are configured such that the signals emitted by the hand-held transmitter are transmitted by Bluetooth, radio, infrared, cable or via a docking station.

6. The radio remote control according to claim 1, wherein the hand-held transmitter has receiving means, by means of which the hand-held transmitter receives signals.

7. The radio remote control according to claim 6, wherein the receiving means are configured such that signals transmitted by Bluetooth can be received with the receiving means.

8. The radio remote control according to claim 1, wherein the radio remote control furthermore comprises one or more master parts which have receiving means, by which the signals emitted by the hand-held transmitter can be received.

9. The radio remote control according to claim 8, wherein the radio remote control is configured such that by one hand-held transmitter two or more than two master parts can be addressed and/or that one master part is associated to two or more than two hand-held transmitters.

10. The radio remote control according to claim 8, wherein the master part includes control links which are freely programmable.

11. The radio remote control according to claim 8, wherein the master part has interfaces, preferably bus interfaces with the crane and/or travel control.

12. The radio remote control according to claim 11, wherein the interfaces are of the two-channel type.

13. The radio remote control according to claim 8, wherein solenoid valves are directly connected to the master part, which has power and/or switching outputs for driving the same.

14. The radio remote control according to claim 8, wherein the master part has transmitting means, by which signals can be transmitted to the hand-held transmitter.

15. The radio remote control according to claim 14, wherein the master part is configured such that software for programming the hand-held transmitter can be transmitted to the same by the master part.

16. The radio remote control according to claim 14, wherein the master part is configured such that diagnostic messages can be transmitted to the hand-held transmitter by the master part.

17. The radio remote control according to claim 1, wherein the radio remote control has a plurality of master parts, which are configured such that data can be transmitted from one to another master part.

18. The radio remote control according claim 1, wherein the radio remote control has a plurality of hand-held transmitters, which are configured such that data can be transmitted from one to another hand-held transmitter.

20. A radio remote control system including a first radio remote control or some other first unit, with which a second radio remote control can be connected, wherein the second radio remote control is the hand-held transmitter of a radio remote control according to claim 1.

24. A crane, preferably a mobile crane, configured with at least one radio remote control according to claim 1.

25. The crane according to claim 24, wherein the crane has one or more master parts, which are disposed on the crane.

26. The crane according to claim 24, wherein the crane includes an uppercarriage and an undercarriage, which each have a master part.

27. The crane according to claim 24, wherein the crane includes a boom, which has a master part.

28. The hand-held transmitter of a radio remote control according to claim 1.

29. The master part of a radio remote control according to claim 8.

19. A radio remote control system for controlling one or more functions of a crane, preferably a mobile crane, wherein the radio remote control system includes a first radio remote control or some other first unit, with which a second radio remote control can be connected.

21. The radio remote control system according to claim 19, wherein the radio remote controls are configured such that one or more functions of one radio remote control are performed by the other radio remote control when the radio remote controls are connected with each other, or that the first unit and the second radio remote control are configured such that one or more functions of the first unit are performed by the second radio remote control and/or vice versa, when the first unit and the second radio remote control are connected with each other.

22. The radio remote control system according to claim 19, wherein the connection between the two radio remote controls or between the first unit and the second radio remote control is configured as a plug connection.

23. The radio remote control system according to claim 19, wherein the first unit is configured as a mobile part or is fixed.
