徴とする非常停止装置付きの昇降装置。 It consists of a fixed part and a driving part attached to it.The fixed part has a main body of a desired length and a driving chain, and an emergency chain is formed in parallel with this.The driving part has a mounting frame body. A drive sprocket is connected to the motor and the shaft of the motor, and an emergency sprocket is also connected to the shaft via a joint.Furthermore, the drive chain and drive sprocket are normally connected to the load condition. The emergency chain and emergency sprocket are kept in a no-load state, and when the drive chain and drive sprocket are no longer loaded, the emergency sprocket and emergency chain become loaded. At this time, one end of the stopper pin that is thrust into the engagement recess of the joint body is engaged and disengaged, so that the other end protrudes toward the surface of the sprocket and is engaged with the stopper provided on the frame. A lifting device with an emergency stop device, characterized in that:
