ABSTRACT:
A counterweight handling device for construction equipment such as cranes in which a counterweight can be elevated to a predetermined height by using particulate hydraulic components then supported on a mounting frame. The counterweight may be supported by a pair of rectangular rotating blocks mounted on the counterweight mounting frame and which slide through a pair of vertical grooves in vertical position into supporting hollows in the counterweight bottom and turn through 90.degree. so as to support the counterweight by blocking the vertical grooves. Alternatively a pair of sliding pins mounted on the counterweight mounting frame may be extended into inverted V shaped notches on the counterweight bottom so as to support the counter weight. The counterweight can then be fastened on the counterweight mounting frame. Later the counterweight can be removed.
