Patent
CA 2658131
In a first aspect, the invention is directed to a manipulator that is relatively compact and has a relatively large range of motion. The manipulator includes a linkage that folds back on itself, which reduces the footprint of the linkage. In a particular embodiment, the manipulator includes a linkage and a load balancing device. The linkage includes a first link, a second link, a third link and a fourth link. The first link and second links are rotatably connected to a base about first and second connection axes. The third and fourth links are connected to the first and second links respectively about third and fourth connection axes respectively. The third and fourth links are rotatably connected to a lift arm about fifth and sixth connection axes respectively, wherein the fifth and sixth connection axes are horizontally displaced from the third and fourth connection axes in the direction of the first and second connection axes. The load balancing device is configured to support the linkage in a selected position against a load and configured to permit the load to be moved upwards or downwards with a selected amount of force on the lift arm. The manipulator may be provided as part of a load maneuvering system that further includes a transport system that may be similar to that used on an overhead crane.
