Length adjustable wire rope rigging device and lifting system employing the same
First Claim
1. A wire rope device having adjustable length between a first end and a second end thereof, the wire rope device comprising:
- a first wire rope extending from the first end and a second wire rope extending from the second end;
a length adjusting structure disposed between the first end and the second end, the length adjusting structure having the first wire rope and the second wire rope connected thereto;
a support structure disposed between the first end and the second end, the support structure having the length adjusting structure rotatable movable mounted thereto;
a first guiding structure and a second guiding structure disposed in the support structure for guiding the first wire rope and the second wire rope, respectively, such that when in operation a portion of the first wire rope extending from the first guiding element and a portion of the second wire rope extending from the second guiding element are disposed substantially along a same straight line; and
,a drive mechanism mounted to the support structure and connected to the length adjusting structure for adjusting the length of the wire rope device by rotatably moving the length adjusting structure.

Abstract
A wire rope device having adjustable length between a first end and a second end thereof. The wire rope device comprises a first wire rope extending from the first end and a second wire rope extending from the second end. A length adjusting structure is disposed between the first end and the second end. The length adjusting structure has the first wire rope and the second wire rope connected thereto. A support structure is disposed between the first end and the second end. The support structure has the length adjusting structure rotatable movable mounted thereto. A first guiding structure and a second guiding structure are disposed in the support structure for guiding the first wire rope and the second wire rope, respectively, such that when in operation a portion of the first wire rope extending from the first guiding element and a portion of the second wire rope extending from the second guiding element are disposed substantially along a same straight line. A drive mechanism is mounted to the support structure and connected to the length adjusting structure for adjusting the length of the wire rope device by rotatably moving the length adjusting structure.
