ABSTRACT:
In a weight compensating apparatus, particularly for a medical device, a cable drum accepts a supporting cable which carries a load, this drum being biased by the force of a spiral spring element. A safety arrangement triggers a stopping arrangement given a breakage of the spiral spring element. The safety arrangement responds particularly to a breakage of the outer region of the spiral spring element.
