ABSTRACT:
An apparatus is provided for loading an object, such as a boat, onto a carrier vehicle having a support mechanism for receiving the object. The apparatus comprises a pair of lift arms mounted for vertical swinging movement about a horizontal rotary axis. Outer ends of the lift arms are connectible to the object. A power winch assembly includes a cable for swinging the lift arms about the rotary axis. A cable fulcrum is mounted on the carrier vehicle and is engaged by the cable. The power assembly is actuable to first wind-in the cable to raise the lift arms and thereafter pay-out the cable to allow the object to gravitate onto the ground or support structure. The cable fulcrum is movable between positions located on opposite sides of the rotary axis during loading and unloading modes, respectively, to enable the center of gravity of the object to be shifted past the rotary axis, without the need for operator assistance.
