Abstract

PURPOSE: To produce a larger retarding torque with a smaller damping driving force by infolding a reactionary fixing end of a brake band and by generating clamping force, using the revolution of a brake drum.
CONSTITUTION: A band 5 is wound up with a certain gap maintained over the surface of a brake drum 4 which revolves as one piece with a drum 3 wound up by a rope 2 which hangs a load 1. One end of the band 5 is fastened by a pin 6. The other end is installed in the mieddle of a movable block 14. When a push up force is not generated by extending operation of a thruster 12, a block 14 is rolled up in the rotating direction of the drum 4 by the force of a spring 13. The band 5 connected with the drum 4 is also pulled up as rolling. Therefore, this simple construction device can generate a larger retaining torque with a smaller damping driving force.
