Abstract

A pipe coil lifting device includes a superstructure with a central longitudinal member and at least two supports attached to opposite sides of the central longitudinal member, with two channels at the outside long-edges of the superstructure attached to the supports, with a convex upper surface attached to the supports of the superstructure.

First claim

What is claimed is:

1. A pipe coil lifting device comprising:
a first channel configured to accommodate a first tine of a forklift;
a second channel configured to accommodate a second tine of the forklift;
a central longitudinal member that extends parallel to the first channel and the second channel;
a first support attached to the first channel and the central longitudinal member;
a second supports attached to the second channel and the central longitudinal member; and
a convex upper surface attached to the central longitudinal member and to upper edges of the first support and the second support, wherein the central longitudinal member is exposed through the convex upper surface.

2. The pipe coil lifting device of claim 1 , wherein the convex upper surface comprises:
a first upper surface section attached to a first top surface of the first channel and a first side surface of the central longitudinal member; and
a second upper surface section attached to a second top surface of the second channel and a second side surface of the central longitudinal member.

3. The pipe coil lifting device of claim 1 , wherein the central longitudinal member comprises end members at opposite ends of the central longitudinal member.

4. The pipe coil lifting device of claim 1 , wherein the convex upper surface overlaps upon a first outside surface of the first channel and a second outside surface of the second channel to facilitate stiffening the pipe coil lifting device.

5. The pipe coil lifting device of claim 1 , comprising a coating applied on the convex upper surface.

6. The pipe coil lifting device of claim 1 , wherein the convex upper surface comprises:
a first curve that changes the convex upper surface from a first radius of curvature to a second radius of curvature to facilitate protecting an interior surface of a pipe coil loaded on the pipe coil lifting device; and
a second curve that changes the convex upper surface from the first radius of curvature to the second radius of curvature to facilitate protecting the interior surface of the pipe coil loaded on the pipe coil lifting device.

7. A method for lifting a pipe coil comprising:
inserting a pipe coil lifting device into an interior channel of the pipe coil, wherein the pipe coil lifting device comprises:
a first channel that accommodates a first tine of a forklift;
a second channel that accommodates a second tine of the forklift;
a central longitudinal member that extends parallel to the first channel and the second channel;
a first supports perpendicular and attached to the first channel and the central longitudinal member;
a second support attached to the second channel and the central longitudinal member; and
a convex surface attached to the central longitudinal member and to upper edges of the first support and the second support, wherein the central longitudinal member is exposed through the convex upper surface; and

lifting the pipe coil using the pipe coil lifting device.

8. The method of claim 7 , wherein the convex upper surface of the pipe coil lifting device comprises:
a first upper surface section attached to a first top surface of the first channel and a first side surface of the central longitudinal member; and
a second upper surface section attached to a second top surface of the second channel and a second side surface of the central longitudinal member.

9. The method of claim 7 , wherein the central longitudinal member comprises end members at opposite ends of the central longitudinal member.

10. The method of claim 7 , wherein the convex upper surface of the pipe coil lifting device comprises:
a first curve that changes the convex upper surface from a first radius of curvature to a second radius of curvature to facilitate protecting an interior surface of the pipe coil; and
a second curve that changes the convex upper surface from the first radius of curvature to the second radius of curvature to facilitate protecting the interior surface of the pipe coil.

11. The method of claim 7 , wherein lifting the pipe coil using the pipe coil lifting device comprises:
inserting the first tine of the forklift into the first channel of the pipe coil lifting device;
inserting the second tine of the forklift into the second channel of the pipe coil lifting device; and
lifting the pipe coil at least in part by operating the forklift to raise the first tine and the second tine.

12. The method of claim 7 , wherein lifting the pipe coil using the pipe coil lifting device comprises lifting the pipe coil lifting device using the forklift.

13. The method of claim 12 , wherein the convex upper surface overlaps upon a first outside surface of the first channel and a second outside surface of the second channel to facilitate stiffening the pipe coil lifting device.

14. The method of claim 12 , wherein the pipe coil lifting device comprises a coating applied on the convex upper surface of the pipe coil lifting device.
