BRAKE DEVICE FOR HOISTING MACHINE

摘要

　Provided is a novel brake device for a hoisting machine wherein a deformable elastic body is used to suppress movement speed of a movable iron core and muffle collision sounds. The elastic body is designed so as to deform in a compressing manner by moving from a designated position in the movement direction of the movable iron core without being compressed to a designated position in the movement direction of the movable iron core. Collision noises are reduced due to the elastic body being compressed and the operating speed of the movable iron core being reduced as the movable iron core moves. In addition, the elastic body bulges in a circumferential direction by compressing and the elastic body comes in contact with the movable iron core, whereby vibration of the movable iron core can be damped.
