Half-moon lifting device
Nonlimiting embodiments including methods and apparatus are provided for moving coils of flexible pipe. A pipe coil lifting device comprises a superstructure having a pair of longitudinal channels attached to and forming sides of an outermost portion of the superstructure, a longitudinal central member extending between the channel portions, the superstructure having at least one cross-member perpendicular and attached to the central member and channel portions, and wherein the top of the superstructure forms a convex upper surface attached to the channel portions, central member and cross-members.
1. A pipe coil lifting device comprising: a superstructure with a central longitudinal member and at least one cross-member, with two channels at the outside long-edges of the superstructure attached to the cross-members, with a convex upper surface attached to the cross-members of the superstructure.
2. The pipe coil lifting device of claim 1 wherein the upper surface is attached to and overlaps upon the outside surface of the channels.
3. The pipe coil lifting device of claim 1 further comprising a device member attached to the central member and an end member attached to the central member.
4. The pipe coil lifting device of claim 1 wherein the central longitudinal member extends beyond the upper surface and comprises an end member for attaching cable fittings.
5. The pipe coil lifting device of claim 1 further comprising half-pipes attached to the lateral outside surfaces of the channels.
6. The pipe coil lifting device of claim 1 further comprising a ¼ inch round bar attached to the arcuate edge of the convex upper surface.
7. A pipe coil lifting device comprising: a superstructure having a pair of longitudinal channel portions attached to and forming sides of an outermost portion of the superstructure, a longitudinal central member extending between the channel portions having at least one cross-member perpendicular and attached to the central member and channel portions, and wherein the top of the superstructure forms a convex upper surface attached to the channel portions, central member and cross-members.
8. The pipe coil lifting device of claim 7 wherein the upper surface overlaps upon the outside surface of the channel portions.
9. The pipe coil lifting device of claim 7 further comprising a device member attached to the central member and an end member attached to the central member.
10. The pipe coil lifting device of claim 7 wherein the longitudinal central member extends beyond the upper surface and comprises an end member for attaching cable fittings.
11. The pipe coil lifting device of claim 7 further comprising half-pipes attached to the lateral outside surfaces of the channel portions.
12. The pipe coil lifting device of claim 7 further comprising a round bar attached to the arcuate edge of the convex upper surface.
13. A method for lifting a pipe coil comprising: lifting a coil of flexible pipe with a pipe coil lifting device, the pipe coil lifting device comprising a superstructure with a central member and at least one cross-member perpendicular to the central member, with two channels at the outside long-edges of the superstructure, with a convex surface attached to the cross-members of the superstructure.
14. The pipe coil lifting device of claim 13 further comprising a device member attached to the central member and an end member attached to the central member.
15. The method of claim 14 wherein the pipe coil lifting device is attached by a cable to the end member.
16. The method of claim 15 wherein the pipe coil lifting device is attached by a cable to a crane for moving a pipe coil.
17. The method of claim 13 wherein the pipe coil lifting device is mounted on a fork lift.
18. The method of claim 17 wherein the pipe coil lifting device is secured to the channels of the fork lift by hydraulic force applied to the fork lift tines.
19. The method of claim 13 wherein the pipe coil lifting device is secured with a cable to the pipe coil lifting device.
