Filed: 1995-03-03
Abstract: PURPOSE: To prevent a subject to be suspended from falling by restraining the rotation of a drum by insertion of a locating pin into a locating pin by means of a pushing member in the event that the supply from an air pressure source is cut off. CONSTITUTION: As air pressure is introduced into a working chamber 58, a locating pin 52 is put into sliding motion resisting the pushing force of a pushing member 66 and is drawn out of a locating hole 44. When acted upon by the air pressure, a piston 22 is put into linear motion and rotates a drum 8 at reduced speed to keep balance with a subject 14 to be suspended that is being suspended from a hanging rope 12. If the air pressure being introduced is cut off by some cause, the locating pin 52 is put into sliding motion toward the locating pin 44 by the pushing force of the pushing member 66 and inserted into the locating pin 44. Thus even if a turning force caused by the weight of the subject 14 to be suspended works on the drum 8, the drum 8 is restrained from turning, and the subject 14 to be suspended does not fall.
