lift and method

Abstract

An elevator comprising: an elevator car (1) arranged to move in an elevator shaft (S); a brake (2) on the elevator car (1); a lever mechanism (12) connected to the brake (2) , 17, 18), by moving the lever mechanism relative to the elevator car, the brake (2) can be moved into the braking position; stopper (5) in the elevator shaft; stopper on the elevator car (6), via which the stop on the elevator car, the aforementioned lever mechanism can be moved in order to cause braking of the brake (2), as well as the stop on the elevator car and in the elevator shaft (5, 6) Can be brought into a relative position of the stop (5, 6) on the collision course by causing at least one movement of the stop (5, 6). The elevator includes: a controllable device (7, 8, 9) for influencing the position of the stopper (6), by controlling the device (7, 8, 9), the stopper (6) can be in position Movement between I and position II, in which the stop (6) on the elevator car and the stop (5) in the elevator shaft are on collision course with each other, and in position II, where the stop (5) , 6) not on the collision course; controller (10) for controlling the equipment (7, 8, 9).

Description

technical field [0001] The object of the invention is an elevator and a method for creating a safety space at the end of an elevator shaft, preferably an elevator suitable for transporting people and / or goods. Background technique [0002] A large number of different elevator safety devices are known from the prior art, with which a temporary safety space for maintenance personnel is realized at the end of the elevator shaft. Known in the prior art is, for example, a type of arrangement in which a movable stop in the elevator shaft is arranged to move into the passage of an actuated stop of a safety device provided on the elevator car middle. When the stoppers meet, the safety device on the elevator car moves to the braking position. The movement of the elevator car can thus be restricted for periods of time when the serviceman is on the roof of the elevator car or in the pit. Otherwise, maintenance personnel could easily be squeezed between the elevator car and the end o...

Problems solved by technology

Another problem has been to actuate the stopper safely and reliably, i.e. to move the stopper to a relative position so that the stopper is on the impact path
