Abstract:
The present invention discloses a solution for optimizing the transport capacity of an elevator system. For optimizing the transport capacity the elevator system dynamically locks floors served by it on the basis of defined locking rules.
Abstract:
An elevator includes a hoistway, and an elevator car and a counterweight vertically movable in the hoistway. The elevator includes at least one first stationary mounted rope wheel positioned in proximity of the upper end of the hoistway, and at least one second stationary mounted rope wheel positioned in proximity of the upper end of the hoistway, the at least one first stationary mounted rope wheel and the at least one second stationary mounted rope wheel being horizontally spaced apart and rotating on different vertical planes of rotation, and a roping, including at least one belt-shaped rope interconnecting the elevator car and counterweight and including a rope portion extending between the car and counterweight, which passes around the at least one first stationary mounted rope wheel and around the at least one second stationary mounted rope wheel, and at least one intermediate stationary mounted rope wheel, positioned at a distance apart from the at least one first rope wheel and the at least one second rope wheel to rotate on a plane of rotation that intersects the plane of rotation of the at least one first rope wheel and the plane of rotation of the at least one second rope wheel, and arranged to guide the portion of the rope extending between the at least one first rope wheel and the at least one second rope wheel to pass from the plane of rotation of the at least one first wheel to the plane of rotation of the at least one second wheel along the plane of rotation of the at least one intermediate stationary mounted rope wheel.
Abstract:
An elevator arrangement includes a plurality of elevators in a building, which plurality includes a plurality of zoned elevators moving in an elevator hoistway, which have different ranges of movement of the elevator car in the building to each other, and which zoned elevators each have a top limit and a bottom limit of the range of movement of the elevator car, to above the top limit and to below the bottom limit of which range of movement travel of the elevator car of the zoned elevator in question is prevented. The vertical location, in relation to the building, of the top limit and/or bottom limit of the range of movement of the elevator car of each aforementioned zoned elevator can be changed. The arrangement also comprises a lobby elevator, the range of movement of the elevator car of which differs from the ranges of movement of the elevator cars of the aforementioned zoned elevators, and the stopping floors of the lobby elevator comprise a plurality of lobby floors, each of which is a stopping floor of one or more zoned elevators belonging to the aforementioned zoned elevator plurality. A method is provided for re-adjusting the elevator arrangement, wherein the range of movement of the elevator car of the zoned elevator in question is changed to reach to a different height in the elevator hoistway by changing the vertical location in relation to the building of the top limit and/or the bottom limit of the range of movement of the elevator car of the zoned elevator in question.
Abstract:
An elevator car arrangement includes an elevator car body and an elevator car sling. The elevator car arrangement further includes a hanging damper arranged to connect the elevator car body and the elevator car sling together for dampening vibrations coming from guide rails through the elevator car sling to the elevator car body. The hanging damper includes a first part connected to a bottom part of the elevator car body; a second part connected to the elevator car sling; and a damping element arranged to dampen vibrations coming from the second part to the first part. A method for dampening vibrations coming from guide rails through the elevator car sling to the elevator car body is disclosed.
Abstract:
The invention relates to an elevator having a car and guide rails along which the car is guided along a hoistway between landings of the elevator, the car comprising: a frame, upper and lower guide elements, which are mounted to said frame at a vertical distance from each other, and exactly one elevator cabin with a cabin floor, in which elevator the cabin is—in travel direction of the car—movably connected to the frame between an uppermost and a lowermost position. By this means a high travel comfort can be obtained with economic space usage at the top and bottom of the hoistway.
Abstract:
An elevator includes an elevator car, a counterweight and suspension roping, which connects the elevator car and counterweight to each other, and which suspension roping includes one or more ropes, which include a load-bearing composite part, which includes reinforcing fibers in a polymer matrix. The elevator car and the counterweight are arranged to be moved by exerting a vertical force on at least the elevator car or on the counterweight. The elevator includes a device separate from the suspension roping for exerting the force on at least the elevator car or on the counterweight.
Abstract:
An elevator includes at least one elevator car and a counterweight which are at least partly suspended on hoisting ropes and a drive machine driving a traction sheave engaging the hoisting ropes for moving the elevator car along guide rails in an elevator shaft, which elevator further includes a compensation rope. The compensation rope is led upwards to an upper part of the elevator shaft and from there aside to a balancing area located aside of the travel paths of the car and counterweight. This solution is particularly adapted for high travel elevators facing horizontal forces during operation as e.g. ship elevators. Collision of compensation ropes are avoided in the area below the car and counterweight paths which could affect the elevator safety when subjected to high horizontal forces, e.g. during rough sea.
Abstract:
Method and arrangement in the manufacture of an elevator, which includes during construction time an elevator hoistway, an elevator car, hoisting roping, a supporting structure including a plurality of support elements movable between a position extended from the supporting structure towards the side and a position retracted towards the supporting structure, and a platform. A plurality of lifts are performed, in each of which lifts the supporting structure is lifted higher up in the elevator hoistway, while the support elements are in the retracted position, after which the support elements are displaced into the extended position and the supporting structure is lowered to rest on top of the structures of the building supported by the support elements in the extended position for the vertical support of the supporting structure in the elevator hoistway, and between lifts the elevator car is used for transporting passengers and/or freight between floors.
