Claims
- 1. A pendant responsive crane control system, comprising:
a swinging link between a hoist for lifting a load and a crane drive for moving said hoist; lateral movement sensor means that generates signals in response to lateral movement of said swinging link; and crane control means directing lateral movement of said crane drive in response to the signals generated by said sensors.
- 2. A pendant responsive crane control system as set forth in claim 1, wherein said swinging link is directly connected to said crane drive.
- 3. A pendant responsive crane control system as set forth in claim 1, wherein said swinging link is directly connected to said crane drive by a universal joint.
- 4. A pendant responsive crane control system as set forth in claim 1, wherein said sensor means generates signals indicating direction of lateral movement.
- 5. A pendant responsive crane control system as set forth in claim 1, wherein said sensor means generates signals indicating the direction and magnitude of lateral movement.
- 6. A pendant responsive crane control system as set forth In claim 1, further comprising a load sensor that generates load signals in response to the load thereon.
- 7. A pendant responsive crane control system as set forth in claim 6, wherein said load sensor is located above said hoist.
- 8. A pendant responsive crane control system as described in claim 7, wherein said swinging link includes said load sensor.
- 9. A pendant responsive crane control system as set forth in claim 8, wherein said load sensor is a load cell.
- 10. A method for controlling a pendant responsive crane system, comprising:
generating lateral movement signals via lateral movement sensors responsive to lateral movement of a swinging link positioned between a hoist for lifting a load and a crane drive for moving said hoist; and directing lateral movement of said crane drive via a crane control means responsive to the signals generated by said sensors.
- 11. A method for controlling a pendant responsive crane system as set forth in claim 10, said first step further comprising generating load signals via load sensors.
- 12. A pendant responsive crane control system, comprising:
a swinging link between a hoist for lifting a load and a crane drive for moving said hoist; lateral movement sensor means that generates signals in response to lateral movement of said swinging link indicating the direction and magnitude of said lateral movement; a load sensor generating load signals in response to the load thereon; and crane control means directing lateral movement of said crane drive in response to the signals generated by said sensors.
- 13. A pendant responsive crane control system as set forth in claim 12, wherein said swinging link is directly connected to said crane drive by a universal joint.
- 14. A pendant responsive crane control system as set forth in claim 12, wherein said load sensor is located above said hoist.
- 15. A pendant responsive crane control system as described in claim 12, wherein said swinging link includes said load sensor.
- 16. A pendant responsive crane control system as set forth in claim 12, wherein said load sensor is a load cell.
