ABSTRACT:
The invention comprises an improved mechanism for lifting and orienting or tilting objects about a definable pivot axis of rotation. The device is comprised of a quadrilateral frame with each frame member pivotally connected to the adjacent frame members, and wherein one frame member is adapted to be externally supported and to allow the frame to be pivoted about a first generally horizontal axis of rotation, and the opposite side frame member is adapted to support an object, and including a handle for altering the angular relationship of the frame members to thereby pivot or tilt the object about the a second axis of rotation passing through the center of gravity of the object and parallel to the first axis of rotation, and further including mechanism to counterbalance the weight of the frame.
