ABSTRACT:
Apparatus for gripping and lifting objects such as fence posts. A frame carries a pair of grippers that are slidingly movable along the frame to grasp a post or other object. The grippers may pivot so that the object remains in essentially constant vertical orientation despite arcuate motion of a tractor or other lifting machine by which the frame is lifted. The grippers may be actuated by hydraulic or other power provided by the lifting machine.
