Abstract

A method including arranging a plurality of actuators into an operating position, arranging a first upper frame and a second upper frame proximate the actuators, attaching a support to the first upper frame and the second upper frame, wherein the support is located above the actuators, and extending the actuators to engage the support. The method also includes extending the actuators to raise the support, the first upper frame, and the second upper frame to a first position, arranging a first middle frame below the first upper frame and a second middle frame below the second upper frame, retracting the actuators to lower the support, the first upper frame, and the second upper frame to a second position, and attaching the first upper frame to the first middle frame and attaching the second upper frame to the second middle frame.

Claims

1. A method, comprising:

arranging a plurality of actuators into an operating position;

arranging a first upper frame and a second upper frame proximate the actuators;

attaching a support to the first upper frame and the second upper frame,

wherein the support is located above the actuators;

extending the actuators to engage the support;

extending the actuators to raise the support, the first upper frame, and the second upper frame to a first position;

arranging a first middle frame below the first upper frame and a second middle frame below the second upper frame;

retracting the actuators to lower the support, the first upper frame, and the second upper frame to a second position;

attaching the first upper frame to the first middle frame and attaching the second upper frame to the second middle frame; and

removing the plurality of actuators from a location below the support, the first upper frame, the second upper frame, the first middle frame, and the second middle frame.

2. The method of claim 1, which further comprises:

extending the actuators to raise the support, the first and second upper frames, and the first and second middle frames to a third position;

arranging a first lower frame below the first middle frame and a second lower frame below the second middle frame;

retracting the actuators to lower the support, the first and second upper frames, and the first and second middle frames to a fourth position; and

attaching the first middle frame to the first lower frame and attaching the second middle frame to the second lower frame.

3. The method of claim 1, wherein each actuator comprises a telescoping hydraulic cylinder.

4. The method of claim 1, wherein the operating position is a position proximate a wellbore.

5. The method of claim 1, wherein the support is a platform floor.

6. The method of claim 1, wherein the support comprises a back frame, a rear spreader frame, and a setback spreader frame.

7. The method of claim 1, wherein the first upper frame and the second upper frame are arranged in parallel or at least substantially in parallel.

8. The method of claim 1, wherein the first upper frame and the second upper frame are arranged on opposing edges of a wellbore site.

9. The method of claim 8, wherein, the actuators are arranged on opposing edges of a wellbore and between the first upper frame and the second upper frame.

10. The method of claim 1,

wherein the actuators are extendable to at least a first height corresponding to the first position at which the first middle frame may be arranged below the first upper frame and the second middle frame may be arranged below the second upper frame, and

wherein the actuators are retractable to at least a second height corresponding to the second position at which the first upper frame may be attached to the first middle frame and the second upper frame may be attached to the second middle frame.

11. The method of claim 2,

wherein the actuators are extendable to at least a third height corresponding to the third position at which the first lower frame may be arranged below the first middle frame and the second lower frame may be arranged below the second middle frame, and

wherein the actuators are retractable to at least a fourth height corresponding to the fourth position at which the first middle frame may be attached to the first lower frame and the second middle frame may be attached to the second lower frame.

12. A method comprising:

arranging a first upper frame and a second upper frame substantially in parallel;

arranging a frame moving system between the first upper frame and the second upper frame;

attaching a support to the first upper frame and the second upper frame;

operably coupling the frame moving system to the support;

raising, using the frame moving system, the support, the first upper frame, and the second upper frame;

arranging a first middle frame under the first upper frame and a second middle frame under the second upper frame;

lowering, using the frame moving system, the support, the first upper frame, and the second upper frame;

attaching the first upper frame to the first middle frame and attaching the second upper frame to the second middle frame; and

removing the frame moving system from a location below the support, the first upper frame, the second upper frame, the first middle frame, and the second middle frame.

13. The method of claim 12, which further comprises:

raising, using the frame moving system, the support, the first and second upper frames, and the first and second middle frames;

arranging a first lower frame below the first middle frame and a second lower frame below the second middle frame;

lowering, using the frame moving system, the support, the first and second upper frames, and the first and second middle frames; and

attaching the first middle frame to the first lower frame and attaching the second middle frame to the second lower frame.

14. The method of claim 13, wherein the frame moving system comprises a base and a plurality of actuators extending in a typically vertical direction from the base.

15. The method of claim 14, wherein the actuators each comprise a telescoping hydraulic cylinder.

16. The method of claim 12, wherein the first upper frame and the second upper frame are arranged on opposing edges of a wellbore.

17. The method of claim 12, wherein the support is a platform floor.

18. The method of claim 12, wherein the support comprises a back frame, a rear spreader frame, and a setback spreader frame.
