This follows at normal speed Pendulum roller 25 formed by the cams 22 Cam track of the cam wheel 21. At overspeed can the pendulum roller 25 due to the inertia of the Pendulum lever 24 of the cam track no longer follow.
- Pendulum lever 24 At the opposite end of the pendulum roller 25 Pendulum lever 24 is an operating lever 27 on one third axis 28 of the pendulum lever 24 rotatably arranged.
- the operating lever 27 is by means of a Restraint device, for example by means of a Schnäppers relative to the pendulum lever 24 in a rest position held.
- a second nose 29 of the actuating lever 27 dives at normal speed of elevator car 1 between two ratchet teeth 20 when the pendulum roller 25 stands on a cam 22 and is from the path of Ratchet teeth 20 is raised when the pendulum roller 25 stands between two cams 22.
- a first nose 26 is arranged, which at Normal speed of the elevator car 1 between two Ratchet teeth 20 immersed when the pendulum roller 25 on a cam 22 stands and which from the path of Ratchet teeth 20 is raised when the pendulum roller 25 stands between two cams 22. If the speed is too high The elevator car 1 in the downward direction remains the first nose 26 stand between two ratchet teeth 20, the left Flank of the subsequent ratchet tooth 20 on the first Nose 26 is pending and the locking ring 19 and thus the Pulley 17 blocked.
- the elevator car 1 is supported by a support frame 1.4 lower yoke 1.6 and an upper yoke 1.5 carried, whereby that led over the traction sheave, not shown Catenary rope at one end with the upper yoke 1.5 and at the other end is connected to the counterweight, not shown.
- At the lower yoke 1.6 is 1.3 per guide rail Arranged 9, which in an emergency Shut down elevator car 1.
- the elevator car 1 drives by means of the governor rope 6, the pulley 17 of the Speed limiter 5 at a certain Excess speed of the elevator car 1 in the downward direction the cable brake 15 triggers and blocks itself.
- the Cable brake 15 and the blocked speed limiter 5 also block that in the shaft pit Arranged pulley 7 guided limiter rope 6, the Elevator car 1, however, continues to move down, whereby the blocked, connected to the trigger mechanism 8 Limiter 6 engages the safety device 9.
