ABSTRACT:
A remotely controlled winch designed for use with a tower crane located at a building site to enable a building panel to be raised from the bed of a truck into the proper position for installation on the side of the building. The building panel normally rests on one of its side edges on the truck bed. The winch includes a frame which is secured to the hoisting cable of the tower crane. A sheave is secured to the lower end of the frame and has a first cable mounted thereon with the ends thereof being removably secured to the upper end of the building panel. A remotely controlled hydraulic winch is mounted on the frame and has a winch cable extending therefrom which is operatively secured to the other side edge of the building panel adjacent the lower end thereof. The tower crane is initially operated to cause the hoisting cable thereof to be moved upwardly which causes the building panel to be raised from the truck. The hydraulically operated winch is then remotely operated to lower the winch cable thereof so that the building panel is rotated 90.degree. into an upright position.
