Embodiment Construction

[0034] figure 1 A part of the building is shown in a simplified schematic side view with the side walls of the elevator shaft 3 removed and the elevator car 2 approaching the uppermost floor 5 . An elevator drive machine 1 with a traction sheave 1 a, two operating safety brake units 1 b and a brake disc 1 c is preferably fixed to a guide rail 4 at the upper end of an elevator shaft 5 . In this embodiment of the invention, the safety brake unit 1b is a disc brake.

[0035] The elevator is a so-called machine-room-less (MRL) elevator, in which the elevator drive machine 1 with its operating braking unit 1b and traction sheave 1a is located in a suitable space in or adjacent to the elevator shaft 3, preferably in the upper part of the elevator shaft In the region, advantageously just below the top of the elevator shaft 3 . The elevator car 2 is arranged to run up and down in an elevator shaft 3 along guide rails 3 guided by guide shoes. Furthermore, the elevator comprises a coun...

Abstract

The invention relates to an elevator safety brake unit (10b), to an elevator comprising at least two of the aforementioned safety brake units, and to a method for testing the safety brake units. Eachsafety brake unit comprises a frame part (11); a movable composition movably supported on the frame portion; a compression spring assembly associated with the movable composition and adapted to activate braking by pushing the movable composition forward; and a coil assembly (16) of an electromagnet disposed in the frame portion and adapted to release braking by pulling the movable composition rearwardly. Wherein each movable composition comprises at least two movable elements (12); a compression spring (17) for each movable element; and at least one coil assembly (16) adapted to deactivate braking by pulling the at least two movable elements rearwardly.

Description

technical field [0001] The invention relates to an elevator safety brake as defined in the preamble of claim 1, an elevator as defined in the preamble of claim 8 and a method for testing an elevator safety brake as defined in the preamble of claim 11 . Background technique [0002] Elevators are commonly used to transport people up and down in buildings. Passenger safety in elevators is one of the most important aspects. The elevator car must be controlled so that it cannot fall freely or move upwards uncontrollably. In addition, all accelerations and decelerations must be kept within certain safety limits. Furthermore, the elevator car must come to a substantially smooth stop in the correct position on the floor on which it lands. Additionally, the elevator car must be able to leave the floor substantially smoothly. Furthermore, the elevator car must also maintain its position in the floor in case of overload. [0003] For the above reasons, authorities in different c...
