取付装置。 For construction machinery that has a counterweight attached to the rear of the upper revolving body, a vertical plate is fixed to the rear end of the center frame of the upper revolving body, and a pair of left and right square holes are opened in the longitudinal direction in the vertical plate. In addition, a pair of square holes in the front and back direction are drilled in the counterweight to be attached to the rear side of the vertical plate at positions corresponding to the square holes in the vertical plate, and from the front side of the vertical plate, A positioning metal fitting is provided to be inserted through the double-sided hole, and the outer surface of the square part on the counterweight insertion side of the positioning metal fitting is formed so that it is all at the same distance from the axis of the positioning metal fitting, and the vertical plate of the positioning metal fitting is The outer surfaces of the square parts on the insertion side are formed to be at an eccentric distance from each other from the axis of the positioning metal fitting, so that when the positioning metal fitting is inserted when the counterweight is installed,
Select and insert one of the outer surfaces of the rectangular part of the vertical plate insertion side of the positioning metal fitting so that it faces one of the inner surfaces of the square hole of the vertical plate, and then tighten the positioning metal fitting from the rear side of the counterweight. A mounting device for a counterweight, characterized in that the counterweight is fixed in place.
