Claims

[Scope of utility model registration request]

The upper end of the first link and the base of the lever from which the counterweight can be hung are placed at a required position on the construction machine so that the first link and the lever have different rotation centers and are parallel to each other. The lower end of the first link is pivotally connected so as to be rotatable in a vertical plane, and the lower end of the first link and the vicinity of the pivot center of the lever are rotatably connected via the second link. A self-removal device for a counterweight, characterized in that an actuator that can move forward and backward is connected to the counterweight.
