Estimating the term…
A tripping device for engaging an elevator lift cage safety brake has actuating levers arranged at a rotary axle for engaging safety brake wedges of the safety braking device. Each actuating lever has a longitudinal slot matched to the diameter of the rotary axle, wherein the actuating lever is freely movable in the direction of the rotary axle and in the direction of the length of the actuating lever. A torsion spring fixes the actuating lever about the rotary axle. One spring end presses the actuating lever downwardly, wherein the movement of the actuating lever is limited by a lower abutment. The other spring end is detachably connected to a support. An upper abutment limits the movement of the actuating lever upwardly. The lower abutment and the upper abutment are each held at a respective end of a T-shaped shackle, wherein the shackle is fixedly connected to the rotary axle. The freely movable actuating levers facilitate access to the safety brake wedges of the safety braking device and prevent erroneous tripping.
A tripping device for engaging at least one elevator lift cage safety braking device upon actuation by a limiter cable, the elevator having a speed limiter monitoring a speed of the lift cage connected by means of a support cable with a counterweight, wherein movement of the lift cage or the counterweight is transmitted by means of the limiter cable to the speed limiter which initiates stopping of the lift cage in the case of excess speed, the tripping device comprising a rotary axle associated with each safety braking device and a plurality of freely movable actuating levers mounted upon the rotary axle and arranged and constructed to actuate safety brake wedges of the safety braking device upon rotation of the rotary axle.
