カウンタウェイト着脱装置。A weight support stand is provided at the rear end of the base machine, and a gantry that can be raised and lowered is provided at the front of the support stand, and this gantry is configured such that the gantry peak guide sheave protrudes rearward from the weight support stand when it is in a collapsed state. In a construction machine such as a crane or the like, the counterweight is moved up and down behind the weight support stand between the right side of the support stand and the ground; and a weight pushing means for horizontally pushing the loaded counterweight toward the weight support base, and the weight lifting means is for lifting a wire rope pulled out from a drum mounted on the base machine through the guide repeak guide sheave. The weight pushing means passes through a bracket provided at the front part of the weight support stand of the base machine and the counterweight in the front-rear direction, and the front end is connected to the bracket around a horizontal axis. A counterweight for construction machinery, comprising a link member rotatably pivoted to the counterweight, and a pushing member provided at a portion of the link member that projects rearward of the counterweight to exert a weight pushing thrust. Attachment and detachment device.
