Elevator maintenance access systems and methods are provided. The elevator maintenance access systems include a frame defining a structural frame of an elevator car and a moveable element moveably coupled to the frame, wherein the moveable element is moveable relative to the frame between a first state and a second state, wherein when the moveable element is in the second state a maintenance gap is formed to enable access from an interior of the elevator car to an exterior of the elevator car.

This invention is directed to a self-propelled elevator system having multiple motors or one motor, and methods for synchronizing said multiple motors. This invention is also directed to an elevator brake system to be used in said self-propelled elevator system or other types of elevators to increase their level of safety.

A construction arrangement of an elevator, comprises a hoistway, a protection deck arranged within the hoistway for protecting the portion of the hoistway below it from falling objects, wherein the protection deck comprises: a frame mounted on stationary structure of the hoistway, a cover co-operating with the frame and extending across the hoistway, wherein the cover is adapted to protect the hoistway from falling objects and/or water from falling into the hoistway below it. The frame is, without dismantling it, configured to be increased and/or decreased in size, individually in at least one direction in relation to the corresponding adjacent stationary structure, such as wall, of the hoistway. A method for constructing an elevator comprises mounting a protection deck within a hoistway.

The disclosure relates to a lift installation having a lift car which can be moved along a guide rail. The lift installation here comprises at least a first pair of rollers and a second pair of rollers. The guide rail runs between the two rollers of the first pair of rollers and between the two rollers of the second pair of rollers. The lift installation also has an apparatus for subjecting the lift car to a retaining force, wherein there is a horizontal offset between the point at which the retaining force takes effect and the center of gravity of the lift car, and therefore the lift car is subjected to a first torque.

An elevator car (20) comprises: a cab (24) having a top, a bottom, a left side, a right side, a front, and a back, the front having a door (50); and a frame (22) supporting the cab. The cab comprises a perimeter shroud (120; 320; 420; 620) protruding above a surface of the top and leaving a well (130) exposing a central portion of an upper surface (60) of the top; the perimeter shroud protrudes above the upper surface; and the perimeter shroud has, in vertical section, a curved portion.

A floor for use with a glass elevator is provided. The floor includes an upper major surface and a lower major surface opposing the upper major surface. The floor also includes a first side edge and a second side edge opposing the first side edge. A first front edge extends from the first side edge to a first front edge recess. A second front edge extends from the second side edge to a second front edge recess. A first rear edge extends from the first side edge to a rear edge recess. A second rear edge extends from the second side edge to the rear edge recess. The upper and lower major surfaces extend in a continuous, uninterrupted form from the first side edge to the second side edge and from the first and second front edges to the first and second rear edges.

A modular cabin assembly 100 for an elevator 200 is provided. The assembly includes a housing 102 which includes a roof assembly 104, and a floor assembly 118. The roof assembly includes a plurality of first connectors 106 connected with a plurality of perforated brackets 108 and coupled with a plurality of vertical posts 110 and is coupled with each other by means of a plurality of joints 114. Each of the plurality of joints includes a projection 116 at the top face of each joint. The floor assembly includes a plurality of protruding portions 120, and a covering structure 122. A first pillar 128a, a second pillar 128b, and a fourth pillar 128d of at least four pillars 128 coupled with the roof assembly and the floor assembly. A third pillar 128c at least four pillars comprise a second vertical post guide rail, coupled with the roof assembly.

This invention is directed to a self-propelled elevator system having multiple motors or one motor, and methods for synchronizing said multiple motors. This invention is also directed to an elevator brake system to be used in said self-propelled elevator system or other types of elevators to increase their level of safety.

A car for an elevator in an elevator shaft is suspended substantially in the center of gravity thereof at least in a ratio of 2:1 by a carrying apparatus guided via pulleys and is guided through car guides. The car has a car base, a car roof and car walls that define a passenger space. For using the car in a machine room-free elevator, to provide a shaft cross-section as large as possible and to reduce the required shaft pit depth and/or the required shaft head height, at least a first part of one of the pulleys is located between the car base and the car roof and a second part of the pulley is located in the car base or at the same height as the car base or in the car roof or at the same height as the car roof.

Cabin assembly (10) for an elevator system, the cabin assembly (10) comprises a cabin (12), a chassis (14) configured to rotationally support the cabin (12) about a cabin axis (16) extending through the cabin (12), a circular thrust profile (18) arranged on the cabin (12) substantially concentric to the cabin axis (16), and a drive member (68) configured to engage the thrust profile (18) to rotate the cabin (12) about the cabin axis (16).
