An elevator system includes one or more elevator cars configured to travel along a hoistway. One or more rails extend along the hoistway and are operably connected to the one or more elevator cars to guide the one or more elevator cars along the hoistway. Each rail of the one or more rails includes a plurality of rail segments arranged end to end. Each rail segment is affixed to a hoistway wall to transfer vertical loads from the rail segment to the hoistway wall. Each rail segment is secured to the hoistway wall via a plurality of rail support brackets. The vertical loads are transferred from the rail segment to the hoistway wall via at least one rail support bracket of the plurality of rail support brackets.

A fastening system has two fastening elements for mounting a bracket of a rail system of an elevator installation. The fastening elements each have a clamping plate having a through-hole and a receiving sleeve receiving an anchor bolt. The receiving sleeves each have a through-opening for the anchor bolt and an angularly movable ball joint is formed between the clamping plate and the receiving sleeve.

A brake device for a traveling body of an elevator installation brakes on a rail having first and second braking profiles. The brake device includes a forcing element and a counter-support. The forcing element has first and second forcing working faces for acting on the first and second profiles respectively. The counter-support has a first counter-support working face for acting on the first profile, and a second counter-support working face for acting on the second profile. The first forcing working face and the first counter-support working face are arranged opposite one another at the first profile and the second forcing working face and the second counter-support working face are arranged opposite one another at the second profile. The forcing element is spread to bring the first forcing working face into contact with the first profile and the second forcing working face into contact with the second profile.

A support device for supporting a rotary platform of an elevator. The support device includes a first form-fit engagement means at an end of a fixed first guide rail, said end facing the platform, a third form-fit engagement means at an end of a third guide rail fastened to the platform and rotatable with the latter. In an alignment of the platform to a first position, the first and third form-fit engagement means are arranged with respect such that, when the platform deflects, as around an axis arranged in a second direction, the third form-fit engagement means is supported on the at least one first form-fit engagement means.

A foldable elevator structure having a plurality of members is shown having each current member sequentially attached between a preceding member and a succeeding member. This connection schema continues until the last member is attached to the first member and a completed enclosed structure is formed such that all members have been attached. In this fashion, the foldable structure is foldable between each set of two adjacent members.

A guide rail-pillar system is disclosed. The system includes at least one guide rail pillar to guide an actuation of a cabin of a pneumatic vacuum elevator, wherein the at least one guide rail pillar is disposed at an external cylinder assembly. The at least one guide rail pillar includes a first surface. A curved structure is extruded from a first surface of the at least one guide rail pillar, wherein the curved structure enables movement of the cabin in a vertical direction. The at least one guide rail pillar includes at least two grooves disposed on lateral sides. The at least two grooves accommodates a covering sheet for enclosing the external cylinder assembly. The at least one guide rail pillar includes at least three ribs. The at least three ribs connects the at least one guide rail pillar with a base ring and the external cylinder assembly.

A method for refinishing a surface structure of shaft material of an elevator, which extends along a shaft, enables the use of image data to determine an absolute position and/or speed of an elevator car. The elevator includes the elevator car, which is movable in the shaft, a camera, which is arranged at the elevator car and generates the image data from the surface structure, and an evaluating unit, which determines the absolute position and/or the speed of the elevator car from the image data. The surface structure is refinished at least locally in order to increase a distinctiveness of the surface structure in the image data. The shaft material can be, for example, a guide rail, a fastening element of the guide rail, or a shaft wall.

Disclosed is a car mover, configured for autonomously moving an elevator car along a track beam in a hoistway lane, having: a car mover body; a drive wheel operationally connected a lateral side of the car mover body, and configured to rotate about a drive wheel axis; a first guide wheel operationally connected to the lateral side of the car mover body, wherein the first guide wheel is offset from the drive wheel so that, in operation: the first guide wheel engages a lateral sidewall of the track beam when the drive wheel laterally moves on the track beam, to thereby restrict lateral motion of the drive wheel on the track beam.

A system for transferring elevator cars from a first elevator shaft to a second elevator shaft including: a propulsion system configured to move an elevator car through the first elevator shaft and the second elevator shaft; a transfer carriage configured to move the elevator car from the first elevator shaft to the second elevator shaft through a transfer station, the transfer carriage including: an elevator car containment slot to receive the elevator car; and a car retention mechanism configured to secure the elevator car and the propulsion system within the transfer carriage while the transfer carriage moves from the first elevator shaft to the second elevator shaft, wherein the propulsion system is configured to move the elevator car from an elevator system within the first elevator shaft onto the transfer carriage and off the transfer carriage to an elevator system within the second elevator shaft.

A counterweight for an elevator system has an asymmetrical cross section in a horizontal sectional plane. The asymmetrical cross section results in an improved connection of the counterweight to a guide rail, a reduction in a number of components, in particular guide rails, for the elevator system, and a reduction in an installation space for the elevator system thereby simplifying installation of the elevator system.
