A radial flux permanent magnet elevator motor includes a motor frame forming the stator frame having fixing points to be fixed to an elevator guide rail, which frame has a back wall facing and/or abutting with the guide rail, which motor frame includes an axially extending flange protruding away from the back wall in the direction of the rotor, and which motor frame includes at least one axially extending first wall section in a defined radial distance from the axis of the motor frame, which first wall section is configured to support a stator winding of the motor. The rotor includes a central hub protruding into the flange of the motor frame and is rotatively supported within the flange via bearings, which rotor includes a traction sheave in a first radial distance from the motor axis and a ring-like support wall in a second radial distance from the motor axis for supporting permanent magnets, which second distance is larger than the first distance, and whereby the stator winding and the permanent magnets form a radial air gap.

Elevator systems are provided. The systems include an elevator car movable along an elevator shaft, the shaft having a pit floor and a shaft top, the elevator car having an elevator car door sill. A plurality of landings are arranged along the elevator shaft, wherein each landing has a landing door. A car apron assembly is provided that includes a car apron attached to the elevator car at the elevator car door sill, a first triggering element connected to at least one landing door, and a second triggering element operably connected to the car apron. The car apron is deployable from a stowed state to a deployed state when the first triggering element engages and actuates the second triggering element.

A machine assembly for use in an elevator system includes a support structure having a first end connected to an adjacent support member and a second end supported by at least one car guide rail. The support structure is arranged generally perpendicular to the support member and is configured to receive at least one component of the elevator system.

The elevator comprising a car moving upwards and downwards in a well, a controller controlling the elevator, and a well lighting. The method comprises detecting a manual unlocking or a manual opening of a landing door, activating the well lighting automatically when the controller detects a manual unlocking or a manual opening of a landing door.

The composite assembly of the steel structure for lifting equipment comprised of the lifting system, into which the lower parts of vertically connected pillars connected to one another by cross-beams are fixed, with a levelling lifting system comprised of lifting plates (11) that are anchored into a concrete recess using chemical bonds via openings (15), with the structure levelling system comprising an adjusting screw (14), adjusting load-bearing nut (12), and safety nut (13), where the adjusting screw (14) passes through the opening in the lifting plate (10) welded onto the lower part of the lowermost pillar (1) of the structure. The vertical connections (3) of individual pillars (1), on the inner sides of both ends fitted with sets of openings mutually arranged at the angle of 90 degrees, are realized by inner connecting pieces (18) with fixed nuts (21), attached by Allen head screws (20) with safety washers having high resistance to spontaneous releasing due to vibrations via a set of openings. Connection of the cross-beam (2) and pillar (1), fitted with fixed integrated nuts (17), screw connections (4) is realized in the front part of the cross-beam (2) closed by the plate (4b) via oval openings (4a) on the inner side of the structure by Allen head screws (4c), supported by safety washers (4d) with high resistance to spontaneous releasing due to vibrations. The connections (4) are also fitted with mechanical protection by safety plates (7), attached by Allen head screws (22) to the fixed nuts (19) attached into the inside of the section on the side of the cross-beams (2), with corner reinforcements (6) ensuring the stability and perpendicularity of the connection (4) of the pillars (1) and cross-beams (2), further comprising a system for seating the brackets of the guide rails consisting of an oval opening (8) and a T-bolt (16), having a rectangular block (16b) in the rear part and a square block (16a) on the top of it for fixing and levelling the attached elements of the elevator.

An elevator that incorporates a framework that allows multiple autonomous mobile lifts to move independently inside and outside a building or a group of buildings in shafts and corridors in such a way that multiple lifts can share a shaft and/or corridor.

The invention relates to a movable machine room comprising a support platform of a hoisting machine, the support platform comprising one or more releasable mounting mechanisms for releasably mounting the moveable machine room in a hoistway, and a hoisting machine mounted on the support platform; a working platform on top of the support platform, preferably forming a roof of the moveable machine room and/or comprising handrails; and at least one support structure supported by which the working platform rests on the support platform; and wherein each said support structure is selectively actuatable to expand in vertical direction for hoisting the working platform higher above the support platform taking reaction force from the support platform, or to contract in vertical direction for lowering the working platform back towards the support platform. The invention relates to an arrangement and a method implementing the movable machine room.

An elevator installation and a method for lubricating bearings in an elevator hoist machine of the elevator installation ensure that during start-up and subsequent running of the elevator hoist machine the bearings are provided with a mixed film lubrication or an elastohydrodynamic lubrication to optimize bearing life expectation.

The present disclosure relates to a carriage lift assembly including a mast member, a top and bottom bearing assembly, one or more belt members, one or more belt tensioner assemblies, and one or more carriage assemblies. Each belt tensioner assembly defines a first clamping block and a second clamping block for securing a first and a second end, respectively, of a belt member to provide initial tension, and a pair of bolt members adjusted to move a slidable plate member upon which the second block is coupled to provide final tension. Each carriage assembly is removably attached to a corresponding belt tensioner assembly, and defines a center plate and two side plates. Each side plate defines at least a removable set of guiding wheels and a first set of guiding members.

A method of operating an elevator, the elevator having an elevator car, a motor, a controller and a counterweight (CW), the method including, for ascending of the elevator car when loaded with passengers, providing a car occupancy limiter (COL) and activating the COL by the controller for ensuring that the loaded car weighs less than the CW and controlling by the controller of the motor to not use motor rotational power; and for descending of the elevator car when loaded with passengers, where the loaded car weighs more than the CW, controlling by the controller of the motor to not use motor rotational power.
