ABSTRACT:
This invention provides an apparatus and a method of using the apparatus to lift and transport a bulky load, such as a round bale of hay. The apparatus of the invention is a planar frame equipped with sliding block adapted to contact and maintain the load to be lifted against the frame during lift and transport. The frame is further equipped with a cable and associated sheave and attachment means adapted to cause the sliding block to move or not to move relative to the frame upon movement of the frame relative to a support, such as the ground depending upon the method of anchoring the cable. The frame is still further equipped with sites adapted for lifting/rotatable attachment to a 3-point lifting device, such as a farm tractor, having the capability to lift the apparatus and load. The frame and load, upon being lifted by the 3-point lifting device, can either tilt toward or away from the 3-point lifting device or can rise vertically depending the method of attachment of the apparatus to the 3-point lifting device.
