Autonomous eccentric tappet gripping device for emergency braking of lift, has accelerating weight falling on contacts and closing short circuit to stop lifting to next floor and to block further lifting movement during breaking of spring

摘要

The device has an eccentric tappet (2) with a freedom of rotation around bolts (1), where an angular position of the bolts is determined by an influence of a spring (4) e.g. deflection spring, and an accelerating weight (5). Electrical contacts (8) are provided under the accelerating weight. The accelerating weight falls on the contacts and closes a short circuit during breaking of a spring or a spring bracket in order to stop lifting to a next floor and to block further lifting movement.
