Abstract:
PROBLEM TO BE SOLVED: To provide a hoist with a brake torque irrelevant to a friction torque of a clutch device and having no danger of a brake slipping the clutch device by providing a specified brake device and clutch device respectively.
SOLUTION: This chain hoist 1 is provided with an asynchronous motor 9 having a field winding 11 and two-stage planetary gear mechanism 15 arranged on the side separated from the motor 9. A combined clutch/brake unit 16 has two mutually parallel, plane, and ring clutch disks 64, 65. The clutch element 65 is simultaneously a brake disk and the brake ring 78 of the brake lining 76 is rotationally and axially seated relative to the clutch disk 64. Both brake linings 76, 79 are cooperated with a position-fixed brake device 82 and surround an electromagnet 83 along with an electromagnet yoke 84 and an electromagnetic coil 85.
