Safety Mechanism |
摘要 |
A safety means for preventing a cable drum to rotate with overspeed has parallel ratchet wheels which encircle a brake drum. At a periphery of the ratchet wheels are stopping slots wherein latching means are inserted when an overspeed is detected. The slots of the adjacent ratchet wheels are staggered. Thus the braking effect of each ratchet wheel starts at a different point of time.
