Problems solved by technology

However, in the lower shaft part, braking must not be possible with high deceleration rates at which passengers would be injured, the braking distance in the top must not become too large to prevent the danger of rapid passage of the car, for example if the brakes work Changes in conditions, e.g. due to heating or oil vapours

Embodiment Construction

[0036] figure 1 A schematic diagram of a high-rise elevator 10 is shown. It is therefore to be noted that the scale of the drawings does not correspond to actual dimensions, since the height of elevator shafts for high-rise elevators is between 30 and 300 meters, while the width / depth of such shafts is usually between 2-6 meters. Furthermore, components not relevant to this embodiment, such as the elevator drive unit, overspeed governor, ropes and deflection pulleys, are not shown in the figure. The elevator can also have a counterweight.

[0037] The elevator 10 includes an elevator car 12 that runs along elevator guide rails 16 in an elevator shaft 14 . In this embodiment, the elevator guide rails 16 are provided only on one side of the elevator car 12 so that the car 12 is suspended in a so-called "rucksack type suspension". Of course, other suspension types can also be used, in which the elevator guide rails are located, for example, on the opposite side of the elevator...

Abstract

The invention relates to an elevator having a car (62), arranged to be moved along at least one guide rail (64, 66) in an elevator guide way, the car having a brake for braking the car movement by gripping the guide rail, the brake having gripping means (68) for gripping the guide rail and exerting a friction force thereon, and adjusting means (70, 72, 74, 76, 78, 80, 82, 84) for adjusting the gripping means with respect to its friction force exerted on the guide rails in case of braking. The adjusting means are configured to adjust the gripping means depending on the car position in the elevator guide way. The invention allows emergency braking particularly in higher and high rise elevators with a stopping distance which is mostly unaffected by the position of the elevator car in the guide way.

Description

technical field [0001] The invention relates to an elevator having an elevator car arranged to move along at least one guide rail in an elevator guide path. The car has a brake, a device commonly called a safety device, which is capable of immediately braking the movement of the car by clamping the guide rails in case of emergency, particularly in the case of car overspeed when the predetermined car speed is exceeded . Background technique [0002] In an emergency, the brakes should brake the car as quickly as possible without endangering the passengers. The most common triggering criterion is overspeed (eg via an overspeed governor), which can occur in emergency situations eg if the hoisting rope loses support, which is a limit and rare. In some elevators, the brakes can also be triggered on alternative criteria, for example in case of an accident or in the case of a serious failure of an elevator component. Such known elevators cause problems especially in high-rise ele...
