Automatic braking and gripping device for free fall system, has basket braked during recoiling without parasitic energy and without external releasing mechanism, where basket is trapped and fixed in position after obtaining retracing height

摘要

The device has a free falling basket (14) impinged on an impact device (16) in an undamped manner. The impact device is connected with a base, and the basket is braked during recoiling without parasitic energy and external releasing mechanism. The basket is trapped and fixed in position after obtaining a retracing height. A cam disk bearing and a braking segment bearing are arranged on a base plate (1) for rotatably supporting a cam disk and a braking segment, where the base plate is collected with the basket.
