Elevator vibration damping device
An elevator system includes a stationary structure, a first sheave rotationally supported by the structure, a rope supported by the first sheave, and an elevator car supported by the rope. A vibration damping device of the elevator system is positioned at a first termination of the rope, and is configured to reduce vibration waves in the rope, thereby reducing noise in the elevator car.
Deflector sheave bracket for offset bedplate
A deflector sheave mounting bracket for mounting a plurality of individual deflector sheaves of an elevator system includes a top plate, a bottom plate, and a plurality of support plates connected at a first end to the top plate and connected at a second, opposite end to the bottom plate. A plurality of openings for receiving the plurality of deflector sheaves is defined between pairs of adjacent support plates of the plurality of support plates. At least one opening of the plurality of openings is vertically offset and horizontally offset from another of the plurality of openings.
DEVICE FOR LIMITING SWAY IN AN ELEVATOR TRAVELLING CABLE
A device for limiting sway in a travelling cable (6) in an elevator system is provided. The device comprises: a channel extending in a first direction for receiving the travelling cable (6) therein, wherein the channel is configured to be mounted in an elevator hoistway (2) such that the first direction corresponds to a direction of motion of an elevator car (4) within the hoistway (2); and an element (20) configured to move in the first direction along an open side of the channel simultaneously with an elevator car (4) and to push the travelling cable (6) into the channel when the element (20) moves along the open side thereof.
ELEVATOR SYSTEM ROPING ARRANGEMENT
An elevator system includes an elevator car. A first drive assembly engages a first tension member. The first tension member is coupled to the elevator car and to a first counterweight. A second drive assembly engages a second tension member. The second tension member is coupled to the elevator car and to a second counterweight. The first tension member can be coupled to the elevator car at a first position and the second tension member can be coupled to the elevator car at a second position opposite the first position.
Methods and apparatuses for applying a substrate onto an elevator sheave
An elevator maintenance kit is provided for surfacing an elevator sheave that engages with an elevator tension member. The kit includes a substrate with an adhesive backing, and a substrate applicator that is operable to apply the substrate to the sheave as the sheave is rotated. The adhesive backing is operable to attach the substrate to the sheave during the sheave rotation.
Drive system for an elevator installation, elevator installation, and method for installing a drive on a support element of an elevator installation
A drive system for an elevator installation includes a drive and a drive suspension for fastening the drive to a support element of the elevator installation. The drive suspension includes a rotary joint for tiltably mounting the drive on the support element and an adjustment device for setting a tilt of the drive about the rotary joint. The support element can be a guide rail wherein the drive system is arranged in an upper end region of the elevator installation.
Elevator system comprising a plurality of differing support means
An elevator system includes at least one car and at least one counterweight. At least two support means having different physical properties are arranged between the at least one car and the at least one counterweight.
Middle-drive type elevator
A middle-drive type elevator has a lift car, tractor, wire rope, guide pulley and counterweight device. The tractor is installed between the lift car and guide pulley. Both the tractor and guide pulley are disposed above the lift car. The tractor is located below the guide pulley. One end of the wire rope connects to the top of the counterweight device, and the other end connects to the top of the lift car after passing through the guide pulley and a traction wheel on the tractor successively. To make the tractor arranged in the middle, the guide pulley bears the majority of the weight of the lift car and counterweight device, while the tractor only bears the minority of the weight of the lift car and counterweight device. It can effectively reduce the load borne by the tractor and greatly improve the service life of the tractor.
LIFTING SYSTEM WITH COUNTERWEIGHT PULLEYS AND CAGE ALIGNED ON THE SAME AXIS OF SYMMETRY
The invention relates to a lifting system for the transport of persons and for the movement of goods, with a traction unit (G) for a cage or goods hoist (10) provided with relative guides (18, 20), vertically movable inside a vertical run space (12) of a building between areas with a given height difference and provided with a bottom, side walls, a roof and mobile cage doors, in particular an electric wire rope elevator, with traction unit inside said vertical run space of the type called MRL (Machine Room Less), comprising a load supporting frame (14) and relative snub pulleys (28, 30), a moving counterweight (16) with relative guides (22, 24) and a snub pulley of the counterweight (32). In said system, said pulleys of the counterweight (16), of the traction unit (G) and of the frame (14) supporting the load contained in said cage, are aligned on the same axis, allowing the space useful for the movement of the cage to be optimised and thus making it possible to install a traction unit with greater lifting capacity.
Machine room-less elevator
A machine room-less elevator includes a car configured to ascend and descend in a hoistway of an architectural structure, a counter weight configured to ascend and descend reversely to the car, a rope configured to suspend the car and the counter weight, and a hoisting machine configured to drive the rope. A support beam assembly, which is configured to bear not a load of the architectural structure but at least loads of the car, the counter weight, the rope, and the hoisting machine, is supported on a top-story floor beam assembly of the architectural structure.
