Abstract

An elevator for use in handling a tubular includes a first body part coupled to a second body part and at least two slips coupled to each of the first and second body parts. One or more of the slips includes an engagement member for coupling with a mating member of the first body part or the second body part, wherein at least 25% of the engagement member is coupled with the mating member when the slip is in an open position.

First claim

The invention claimed is:

1. A tubular handling tool for handling a tubular, comprising:
a first body part coupled to a first end and a second end of a second body part;
a passive slip attached to each of the first and second body parts; and
an active slip attached to each of the first and second body parts, wherein the active slip includes an engagement member for coupling with a mating member of the first body part or the second body part, wherein at least 80% of a length of the engagement member is coupled with the mating member when the active slip is in an open position and wherein a ratio of the length of the engagement member to a length of the mating member is from 4:1 to 1.25:1, and wherein the engagement member of the active slip is longer than an engagement member of the passive slip.

2. The tubular handling tool of claim 1 , wherein the passive slips of the first and second body parts are positioned on each side of a hinge connection.

3. The tubular handling tool of claim 1 , further comprising a biasing member for biasing the engagement member toward the open position.

4. The tubular handling tool of claim 1 , wherein the passive slip is movable in response to a tubular load.

5. The tubular handling tool of claim 1 , wherein the engagement member is coupled with at least 90% of the mating member when the slip is in the open position.

6. The tubular handling tool of claim 1 , further comprising a stabbing member attached to each of the passive slips.

7. The tubular handling tool of claim 1 , wherein the tubular handling tool is an elevator or a spider.

8. The tubular handling tool of claim 1 , further comprising a piston and cylinder for moving the active slip.

9. The tubular handling tool of claim 8 , wherein the active slips and the passive slips are disposed around an interior of the first body part and the second body part.

10. The tubular handling tool of claim 9 , wherein the piston and cylinder assembly is disposed exterior of the first body part and the second body part.

11. The tubular handling tool of claim 10 , further comprising a connector arm coupling the piston and cylinder assembly to the active slip.

12. The tubular handling tool of claim 11 , wherein the connector arm extends across the first body part or the second body part.

13. The tubular handling tool of claim 12 , wherein the connector arm is slidably attached to a top surface of the active slip.

14. The tubular handling tool of claim 12 , further comprising a spherical bearing for coupling the piston and cylinder assembly to the connector arm.

15. The tubular handling tool of claim 1 , wherein at least a portion of the engagement member extends below the mating member when the active slip is in a lower position relative to the mating member.

16. A tubular handling tool for handling a tubular, comprising:
a first body part coupled to a first end and a second end of a second body part;
a passive slip disposed in and attached to each of the first and second body parts;
an active slip disposed in and attached to each of the first and second body parts, wherein the active slip includes an engagement member for coupling with a mating member of the first body part or the second body part, wherein at least 80% of a length of the engagement member is coupled with the mating member when the active slip is in an open position and wherein a ratio of the length of the engagement member to a length of the mating member is from 4:1 to 1.25:1; and
a piston and cylinder assembly for moving each of the active slips,
wherein at least one of the first body part and the second body part is disposed radially between the piston and cylinder assembly and the respective active slip.

17. The tubular handling tool of claim 16 , further comprising a connector arm coupling the piston and cylinder assembly to the active slip.

18. The tubular handling tool of claim 17 , wherein the connector arm extends across at least one of the first body part and the second body part.

19. The tubular handling tool of claim 18 , wherein the connector arm is slidably attached to a top surface of the active slip.

20. The tubular handling tool of claim 19 , further comprising a spherical bearing for coupling the piston and cylinder assembly to the connector arm.
