うに構成したことを特徴とするピン連結部の安全
装置。 The boom, arm, idler link, push rod, etc. are connected with pins and mutually rotated by hydraulic cylinders, and a work equipment is attached to the tip of the arm to form a work attachment, and the work attachment is attached to the machine body. In a construction machine mounted on the front part, a controller is provided to insert and insert a load cell pin as a pin of a pin connection part in a work attachment and input a load detection signal from the load cell pin,
The present invention is characterized in that when a load exceeding a predetermined value is applied to the rotor cell pin during operation of the construction machine, a load detection signal from the load cell pin is determined by the controller, and an alarm command signal is output from the controller to the alarm device. Safety device for pin connections.
