Abstract

A crane system includes a skid assembly having an operator base and plurality of outrigger assemblies coupled to the operator base that support and lift the base from a first elevation to a second elevation. The crane system also includes a jib crane coupled to the skid assembly. The jib crane includes a pillar assembly coupled to the skid assembly and a boom assembly coupled to the pillar assembly.

First claim

What is claimed is:

1. A crane system comprising:
a skid assembly having an operator base, the operator base including a lower plate configured to rest on a semi trailer, the skid assembly further including a plurality of outrigger assemblies coupled to the operator base that support and lift the operator base from a first elevation to a second elevation, wherein the outrigger assemblies are movable from a fully extended position where portions of the outrigger assemblies extend below the lower plate to support the operator base, to a fully retracted position where the outrigger assemblies are each disposed entirely above the lower plate, wherein each outrigger assembly includes a leg and a lower foot coupled to the leg, the lower foot configured to engage a ground surface in the extended position, wherein the lower foot of each outrigger assembly is configured to extend outwardly over an edge of the lower plate and then downwardly below the lower plate when moving from the fully retracted position to the fully extended position; and
a jib crane coupled to the skid assembly, the jib crane having a pillar assembly coupled to the skid assembly, and a boom assembly coupled to the pillar assembly.

2. The crane system of claim 1 , wherein the plurality of outrigger assemblies includes four outrigger assemblies coupled to the operator base, each of the four outrigger assemblies extending below the operator base, and wherein the jib crane extends above the operator base.

3. The crane system of claim 1 , wherein each of the plurality of outrigger assemblies includes a lower foot that is configured to engage a ground surface.

4. The crane system of claim 1 , wherein the operator base is welded directly to the plurality of outrigger assemblies.

5. The crane system of claim 1 , wherein each of the plurality of outrigger assemblies includes a hydraulic cylinder.

6. The crane system of claim 1 , further comprising at least one camera coupled to the jib crane.

7. The crane system of claim 6 , further comprising a controller that displays feeds from the at least one camera.

8. The crane system of claim 7 , wherein the controller is coupled to the operator base.

9. The crane system of claim 1 , wherein the boom assembly includes a welded structural steel box.

10. The crane system of claim 1 , wherein the pillar assembly extends vertically from the operator base, and the boom assembly extends horizontally from the pillar assembly.

11. The crane system of claim 1 , wherein the pillar assembly is a telescoping assembly and the boom assembly is a telescoping assembly, the crane system further including a controller that controls telescoping vertical movement of the pillar assembly and telescoping horizontal movement of the boom assembly.

12. The crane system of claim 11 , wherein the controller also controls rotational movement of the boom assembly, wherein the boom assembly is rotatable 360 degrees.

13. The crane system of claim 1 , wherein the boom assembly includes a first section coupled to the pillar assembly, a second section telescopingly coupled to the first section, a third section telescopingly coupled to the second section such that the second section is disposed between the first and third sections, and a fourth section telescopingly coupled to the third section such that the third section is disposed between the second and fourth sections.

14. The crane system of claim 13 , wherein a first camera is coupled to the first section and a second camera is coupled to the fourth section.

15. The crane system of claim 14 , wherein a third camera is coupled to the pillar assembly.

16. The crane system of claim 13 , wherein a hoisting component is coupled to the fourth section.

17. The crane system of claim 1 , wherein the lower plate is a substantially planar, rectangular plate.

18. The crane system of claim 1 , wherein the plurality of outrigger assemblies includes a first outrigger assembly, a second outrigger assembly, a third outrigger assembly, and a fourth outrigger assembly, wherein the first, second, third, and fourth outrigger assemblies are spaced equally apart from one another, and wherein when the first, second, third, and fourth outrigger assemblies are in the fully retracted position, the lower foot of the first outrigger assembly faces opposite to the lower foot of the third outrigger assembly and the lower foot of the second outrigger assembly faces opposite to the lower foot of the fourth outrigger assembly.

19. The crane system of claim 1 , wherein vertical plates are coupled to the lower plate, wherein each of the plurality of outrigger assemblies is disposed at least partially between a pair of the vertical plates when in the fully retracted position.
