Abstract

A device comprising a weldment having an upper beam, a vertical beam, and a lower beam, wherein the upper beam further comprises at least two lifting eyes and at least one crane hook, and the lower beam further comprises a plurality of swivel-hoist rings and a plurality of forklift pockets, and wherein the lower beam is a length minimally required to locate a structure laterally underneath an upper level of a platform having an upper level and a lower level.

First claim

We claim:

1. A system comprising a weldment having an upper beam, a vertical beam, and a lower beam, wherein the vertical beam spans the upper beam and the lower beam, wherein the upper beam further comprises a crane hook, a lifting eye for the weldment only, a separate lifting eye for the weldment combined with a structure to be lifted, and a load transfer block, and wherein the lower beam further comprises a plurality of attachment points for enabling attachment of a sling line from a bottom of the weldment to a base of the structure, and a plurality of forklift pockets.

2. The system of claim 1 , further comprising a plurality of swivel-hoist rings located at the plurality of attachment points.

3. The system of claim 2 , wherein the structure is a building, and the lower beam is a length minimally required to locate the building laterally underneath an upper level of a platform having an upper level and a lower level.

4. The system of claim 3 , wherein the lifting eye for the weldment only coincides with the center-of-mass of the weldment.

5. The system of claim 4 , wherein a load transfer sling is operably connected to the lifting eyes and the crane hook.

6. The system of claim 5 , wherein the weldment is steel.

7. A device comprising a weldment having an upper beam, a vertical beam, and a lower beam, wherein the upper beam further comprises a lifting eye for the weldment only, a separate lifting eye for the weldment combined with a structure to be lifted, and at least one crane hook, and the lower beam further comprises a plurality of swivel-hoist rings for enabling attachment of a sling line from a bottom of the weldment to a base of the structure and a plurality of forklift pockets, and wherein the lower beam is a length minimally required to locate the structure laterally underneath an upper level of a platform having an upper level and a lower level.

8. The device of claim 7 wherein the upper beam further comprises a load transfer block.

9. The device of claim 8 wherein a load transfer sling is operably coupled to the two lifting eyes and at least one crane hook.

10. The device of claim 9 wherein the platform is a pier.

11. The device of claim 10 wherein the weldment is steel.

12. The device of claim 11 wherein the structure is a coastal personnel building.

13. A method for structure installation comprising the steps of:
providing a weldment having an upper beam, a lower beam, and a vertical beam, wherein the upper beam comprises a crane hook, a lifting eye for the weldment only, and a lifting eye for the weldment combined with a structure, and wherein the crane hook and lifting eyes further comprise a load transfer sling, and wherein the lower beam comprises a plurality of swivel-hoist rings;
using a crane to lower the weldment onto a forklift, wherein the crane is coupled to the lifting eye for the weldment only;
using the load transfer sling to transfer the crane hook from the lifting eye for the weldment only to the combined lifting eye;
positioning the weldment above the structure using the forklift;
securing sling lines from the swivel-hoist rings to the base of the structure to create an assemblage including the weldment and the structure;
using the crane to hoist the assemblage off the upper level of a platform, wherein the platform has an upper level and a lower level;
laterally positioning the assemblage outward, and lowering it to just above the lower level;
translating the assemblage laterally and placing it on the lower platform;
using the crane to lower the weldment just enough to create slack in the sling lines to allow for them to be removed from the structure;
using a load transfer block to detach the load transfer sling from the combined lifting eye to the weldment lifting eye;
using the crane to remove the weldment from the platform.

14. The method of claim 13 further comprising the step of recovering the structure by performing the reverse order of the installation steps.
