Problems solved by technology

[0005] In addition to the high structural complexity, such a safety system with speed limiter and limiter rope has the disadvantage that such a safety system only meets the requirements of machine room-less elevator installations to an insufficient extent.
The elimination of the engine room thus results in: Unrestricted accessibility to the speed limiter is no longer ensured

Embodiment Construction

[0055] figure 1An elevator installation 100 is shown, as it is known from the prior art. Displaceably arranged in the elevator shaft 1 is a load receiving device or elevator car 2 , which is connected via a supporting mechanism 3 to a likewise displaceable counterweight 4 . During operation, the support mechanism 3 is driven by the drive pulley 5 of a drive unit 6 which is arranged in the machine room 12 in the uppermost region of the elevator shaft 1 . The elevator car 2 and the counterweight 4 are guided by means of guide rails 7a or 7b and 7c extending at the height of the shaft.

[0056] The elevator car 2 can serve the uppermost floor 8 , the other floors 9 and 10 as well as the lowest floor 11 and thus generate the maximum travel distance S_M. The elevator shaft 1 is formed by the shaft side walls 15a and 15b, the shaft top 13 and the shaft bottom 14, on which a shaft bottom buffer 16a for the counterweight 4 and two shaft bottoms for the elevator car 2 are arranged B...

Abstract

The invention relates to a fall arrest device (38c-38k) on a load receiving device (2; 2a; 2b) of an elevator installation (100; 100a; 100b), the fall arrest device having a brake (300; 300a), The brake cooperates with the guide rail (7b-7e) of the load receiving device (2; 2a; 2b). The brake (300; 300a) comprises a cam disc (55; 55a) rotatable around the cam disc axis, the cam disc turns through an activation angle in order to activate the safety device (38a-38d), wherein the cam disc (55; 55a) is constructed in such a way that the cam disc comes into contact with the guide rail (7b-7e) due to the rotation of the activation angle, whereby the movement of the load-accommodating device (2; 2a; 2b) relative to the fall arrest device (38a-38d) The guide rail (7b-7e) turns the cam disc (55; 55a) into a position in which the brake (300; 300a) and thus the safety device produces the provided, relative to the guide rail (7b ‑7e) braking action. The fall arrest device (38a‑38d) comprises an electrically controlled activation mechanism (45; 45a) with a pivotably supported activation lever (47; 47a) and an activation spring (52), the activation spring (52) If necessary, the cam disc (55; 55a) is rotated through the activation angle by means of the activation lever (47; 47a).

Description

technical field [0001] The invention relates to an elevator installation in which at least one safety system is provided to prevent uncontrolled vertical movements of a load receiving device or a counterweight of the elevator installation. [0002] The safety system includes at least one fall arrest device having a brake that can be brought into an activated, braking state, and into a deactivated, non-braking state, wherein the fall arrest device is activated Connect the load receiving device with the guide rail in a friction-locked state. The non-braking state of the brake is also referred to as the normal operating state. Additionally, the safety system includes at least one activation mechanism that activates the brake. Background technique [0003] Widely used are safety systems which function only mechanically. Here, limiter ropes are used, which are guided around the sheave of the speed limiter in the upper area of ​​the elevator shaft and around the deflection shea...
