  • Patent number: 4128179
    Abstract: Apparatus for loading objects, particularly large cylindrical hay bales upon a motor truck. The bale loader includes a frame which is comprised of a first frame section which is to be semipermanently mounted upon the motor truck, and a demountable second frame section to which the remainder of the bale loader apparatus is attached. To this demountable frame section is attached a boom which is operated by means of a winch and winch line. The boom is in turn connected to a standard tractor three point bale fork. This apparatus in combination with a standard motor truck can be used to lift a large cylindrical hay bale from the ground to a traveling position above the bed of the motor truck, then transport the bale to another location and lower the bale to the ground. In an alternative embodiment of the invention the bale fork is replaced by a lifting boom to create a small crane for lifting and transporting miscellaneous items.
