Problems solved by technology

[0004] (1) Inspection and maintenance holes that are opened when running through necessary inspections For elevator components that extend over the entire shaft height or are distributed in large numbers throughout the shaft height, such as guide rails, load-carrying cables, speed-limiting cables, guide rail fixings, and shafts There is a risk that the inspector's head or arms will hit or become stuck on objects installed in the shaft during the inspection of the transmitter
[0005] (2) There is no safety device that inhibits the operation of the elevator or the inspection operation when the inspection and maintenance opening is open, or that is used to keep the inspection personnel out of the range of the opening during such operation
[0006] (3) When the inspection and maintenance holes are closed, it is difficult to accurately drive to these positions during the inspection run between the positions of the elevator components to be inspected in the elevator shaft because the elevator shaft cannot be seen

Embodiment Construction

[0026] figure 1 Schematic sectional view of a first elevator construction design with a load-bearing nosing system, wherein the elevator car 10 runs in the direction of the arrow 27 in the elevator shaft 11 . The car 10 has a car frame 12 and runs on guide rails 13 via schematically shown guide clips 14 fastened to the car frame 12 and can be moved to a position adjoining the shaft roof 15 of the shaft space 11 . The drive unit 16 is used to move the car 10 and has a drive motor 17 with a brake and a driving wheel 18 . The driving pulley 18 cooperates with the load-bearing cable 19, and the load-bearing cable goes downward from one side of the drive pulley 18, bypasses the cable roller 20 and the car 10, reaches the other side of the shaft, reaches the first cable fixing point 23 upwards and is passed by the drive pulley 18. The other side of the shaft goes down, around the counterweight carrying rollers 22 and up again to a second cable fixing point, not shown, at the top of...

Abstract

An elevator without a machine room, comprising an elevator car (10) which travels in an elevator shaft (11), an elevator control unit which controls at least the travel movements of the elevator; and various elevator components which are mounted in the elevator shaft (11) and which are to be inspected periodically. The elevator car (10) has at least one sealable inspection and maintenance opening (29) in at least one of its side walls (26), said opening being sealed by a transparent inspection window (28.A) or inspection grid (28.B) in a normal mode. When the inspection window (28.B) or the inspection grid (28.B) is open, inspection and maintenance work can be carried out on the elevator components by a person standing in the elevator car. When the inspection window (28.A) or the inspection grid (28.B) is closed, visual inspections can be made from the car (10) and testing and adjusting work can be carried out on the elevator components through suitably placed reach-through openings (31) in the inspection window (28.A) or the inspection grid (28.B).

Description

technical field [0001] The invention relates to a machine room-less elevator with at least one elevator car running in an elevator shaft, with an elevator control which controls the operation of the elevator, with various An inspected elevator component in which the elevator car has at least one closable inspection and maintenance opening in at least one of its side walls. Background technique [0002] Such an elevator is disclosed in JP 10 231074A. Therein, a machine-room-less elevator is described, in which inspection and maintenance of elevator components installed in the elevator shaft or on the elevator car are carried out in such a way that the side walls of the elevator car are provided with closable Inspection and maintenance holes are located within the confines of these elevator components. [0003] The above-mentioned solution to the inspection and maintenance problem in the machine-room-less elevator has the following disadvantages: [0004] (1) Inspection and...
