Abstract
A dual crane apparatus and a method of use are disclosed herein. The disclosed dual crane apparatus generally comprises a support frame and two rotating crane members mounted to the support frame, wherein the crane members can each independently move up and down in a vertical direction, extend and retract in a horizontal direction, and rotate clockwise and counterclockwise. The disclosed dual crane apparatus can be utilized for servicing mobile irrigation systems.
Claims31
A dual crane apparatus, comprising:
- a support frame including:
- a first mounting structure configured for attachment of a first rotating crane member;
- a second mounting structure connected to said first mounting structure via a base, said second mounting structure configured for attachment of a second rotating crane member;
- and
- said base forming the bottom surface of said first mounting structure and said second mounting structure;
- said first and second rotating crane members are able to rotate relative each other;
- said first rotating crane member mounted to said first mounting structure, wherein said first crane member comprises:
- a first vertical arm having a first end and a second end,
- a first telescoping horizontal arm having a first end and a second end, said first end being articulately coupled to said second end of said first vertical arm, and
- a first actuating arm having a first end and a second end, said second end being attached to said first telescoping horizontal arm, wherein said first actuating arm is arranged and configured to move said second end of said first telescoping horizontal arm up and down;
- and
- said second rotating crane member mounted to said second mounting structure, wherein said second crane member comprises:
- a second vertical arm having a first end and a second end,
- a second telescoping horizontal arm having a first end and a second end, said first end being articulately coupled to said second end of said second vertical arm, and
- a second actuating arm having a first end and a second end, said second end being attached to said second telescoping horizontal arm, wherein said second actuating arm is arranged and configured to move said second end of said second telescoping horizontal arm up and down;
- and
- one or more legs attached to said base, wherein said one or more legs hold up said base and said support frame above a ground surface.
