System and method for controlling the lifting and handling of a load

1. A system for connecting a lifting device to a load to be lifted; the system comprising:

a first connector member, the first connector member comprising at least one pin and a torque ring, wherein the torque ring comprises a plurality of teeth arranged on an inner surface of the torque ring; and

a second connector member, the second connector member comprising an indexer mechanism defining a track, the track comprising at least one track opening;

wherein at least a portion of the second connector member is receivable in at least a portion of the first connector member;

wherein at least a portion of the at least one pin is receivable in the track via the at least one track opening; and

wherein the first connector member is reversibly coupleable to the second connector member via the pin and the indexer mechanism in response to a first series of longitudinal movements of the first or second connector members.

2. The system of claim 1 , wherein the pin is located on an inner surface of a body of the first connector member, and the indexer mechanism is located on an outer surface of a body of the second connector member.

3. The system of claim 1 , wherein the pin is movable along the track between a lock position and an unlock position.

4. The system of claim 3 , wherein the pin is located in a load bearing slot of the track in the lock position.

5. The system of claim 3 , wherein the pin is moveable out of the track via the at least one track opening and the first connector member and the second connector member are decoupleable in the unlock position.

6. The system of claim 1 , wherein the second connector member further comprises at least one fin engageable with the plurality of teeth of the torque ring.

7. The system of claim 6 , wherein the indexer mechanism is positioned in a first section of the second connector member and the at least one fin is positioned in a second section of the second connector member.

8. The system of claim 7 , wherein the first section and the second section are independently rotatable.

9. The system of claim 7 , wherein the second connector member further comprises a clutch mechanism that rotationally couples the first section and the second section in a first state and permits independent rotation of the first section and the second section in a second state.

10. The system of claim 9 , wherein the clutch mechanism comprises:

a shaft;

an upper clutch portion located at an upper end of the shaft and comprising a plurality of teeth;

a lower clutch portion located at a lower end of the shaft and comprising a plurality of teeth; and

a spring positioned around the shaft and extending between the upper clutch portion and the lower clutch portion;

wherein the upper clutch portion is engageable with the lower clutch portion in the second state.

11. A method of connecting a load to a lifting device and lifting the load, the method comprising:

coupling a first connector member to the load to be lifted, the first connector member comprising at least one pin and a torque ring, wherein the torque ring comprises a plurality of teeth arranged on an inner surface of the torque ring;

coupling a second connector member to the lifting device, the second connector member comprising an indexer mechanism defining a track, the track comprising at least one track opening, wherein the second connector member further comprises a fin engageable with the plurality of teeth of the torque ring;

inserting the at least one pin into the track via the at least one track opening; and

coupling at least one portion of the second connector member to at least one portion of the first connector member by moving the second connector member in a first series of longitudinal movements relative to the first connector member to reversibly couple the first connector member and the second connector member.

12. The method of claim 11 , wherein coupling the at least one portion of the second connector member to the at least one portion of the first connector member comprises lowering the at least one portion of the second connector member into or around the at least one portion of the first connector member.

13. The method of claim 11 , further comprising decoupling the at least one portion of the first connector member and the at least one portion of the second connector member by moving the second connector member in a second series of longitudinal movements relative to the first connector member.

14. The method of claim 13 , wherein decoupling the at least one portion of the first connector member and the at least one portion of the second connector member comprises supporting the load on a surface.

15. The method of claim 13 , wherein the first series and the second series of longitudinal movements comprise a predetermined sequence of downward and upward longitudinal movements of the second connector member relative to the first connector member.

16. The method of claim 11 , further comprising moving the second connector member in the first series of longitudinal movements to position the pin in a load bearing slot of the track.

17. The method of claim 16 , wherein the second connector member comprises a first section and a second section that are independently rotatable in a first state and are rotationally coupled in a second state.

18. The method of claim 17 , further comprising applying a lifting force to the second connector member to move the first section and the second section to the second state.

19. The method of claim 11 , further comprising transferring torque from the load to the lifting device using a torque ring coupled to the first connector member.

20. A method of connecting a load to a lifting device and lifting the load, the method comprising:

coupling a first connector member to the load to be lifted, the first connector member comprising at least one pin;

coupling a second connector member to the lifting device, the second connector member comprising an indexer mechanism defining a track, the track comprising at least one track opening;

inserting the at least one pin into the track via the at least one track opening;

coupling at least one portion of the second connector member to at least one portion of the first connector member by moving the second connector member in a first series of longitudinal movements relative to the first connector member to reversibly couple the first connector member and the second connector member; and

transferring torque from the load to the lifting device using a torque ring coupled to the first connector member.
