Abstract

PURPOSE: To brake the braking shaft smoothly when the brake is suddenly shifted by forming the brake disk, which tightly holds the brake shoe incorporated with the braking shaft by the pressing force of the brake shoe, with the elastic material.
CONSTITUTION: When the main brake has a trouble and the hanging load falls, the motor shaft 6 is driven reversely and the cetrifugal piece 16 springs out resisting the ring spring 18. The centrifugal piece 16 contacts inner surface of the brake shoe 21 and rotates the shoe 21 which is shifted in the axial direction by the action of the tilting surface of the retainer. As the brake disk 19 which holds the brake wheel 13 incorporated with the motor shaft 6 tightly with the brake shoe 21 has the spring type ratchet which can elastically move back against the brake case 20, the impact force is moderated to smoothly brake the motor shaft 6 in case of the sudden shift of the brake shoe 21.
