10227212 · 2019-03-12 · ·

An elevator arrangement, includes an elevator hoistway, an elevator car, which is arranged to travel in the elevator hoistway, a counterweight, a movable supporting platform above the elevator car, suspension roping, which is connected to the elevator car and to the counterweight, and supports them while suspended from the supporting platform, and a hoisting machine, which includes a device configured to move the roping. The elevator arrangement also includes a hoisting machine and traction roping that are separate from the supporting platform, which hoisting machine is in power transmission connection via the traction roping with the elevator car and with the counterweight.

TENSIONING ARRANGEMENT FOR AN ELEVATOR

The invention relates to a tension arrangement for an elevator, which elevator comprises at least an elevator car arranged to run in an elevator shaft along guide rails, a counterweight or balance weight connected to the elevator car with a traction member from below and suspension ropes from above, and a hoisting machinery equipped with a drive wheel and an elevator motor in the lower part of the elevator shaft. The drive wheel and elevator motor are supported by a lever mechanism which is arranged to allow the drive wheel and elevator motor to move up and down.

Reducing elongation of roping or belting of an elevator by pretensioning the roping or belting of the elevator

Example embodiments relate to an elevator. The elevator may include a car of the elevator and a counterweight that are to be moved reciprocally, at least one roping or belting traveling via a top pulley assembly for connecting the car of the elevator and the counterweight to each other via the top pulley assembly, and at least one roping or belting traveling via a bottom pulley assembly for connecting the car of the elevator and the counterweight to each other via the bottom pulley assembly.

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.

Elevator car

The object of the invention is an elevator car intended for transporting people and freight, in an elevator wherein the elevator car is supported resting on suspension members and arranged movably in an elevator hoistway when moved by a hoisting machine. At least the floor and roof of the elevator car are composed of dimensionally precise modular elements fabricated by casting, extruding and/or pressing into their shapes and dimensions.

ARRANGEMENT FOR ADJUSTING THE TAUTNESS OF A TRACTION MEMBER OF AN ELEVATOR

The object of the invention is an arrangement for adjusting the tautness of a traction member of an elevator, which arrangement comprises an elevator car and a compensating weight, which are for their part connected to support the elevator car by the aid of a suspension member, such as a rope or belt, and also a hoisting machine provided with a traction sheave, and one traction member, such as a belt, which is adapted to transmit the rotational movement of the traction sheave into movement of the elevator car and of the compensating weight, and also a tension control means, which is arranged to adjust the magnitude of the tension forces exerted on the suspension member and on the traction member. The arrangement comprises a tensioning means connected to the traction member, and the tension control means is connected to that part of the traction member that is on the side of the compensating weight with respect to the traction sheave, and the tensioning means is connected to that part of the traction member that is on the side of the elevator car with respect to the traction sheave.

Elevator with compensation rope
09695012 · 2017-07-04 · ·

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.

Elevator arrangement

The object of the invention is an elevator arrangement, which comprises at least an elevator car configured to move up and down in an elevator hoistway and at least two compensating weights, which are for their part connected to support the elevator car by the aid of their own support means, such as by the aid of ropes or belts and also e.g. diverting pulleys, and a hoisting machine provided with at least one traction sheave or corresponding, and at least one traction means such as a rope or belt, which is configured to transmit the rotational movement of the traction sheave into movement of the elevator car and of the compensating weights. Each compensating weight is connected by the aid of a traction means to the same hoisting machine.

VERTICALLY AND HORIZONTALLY MOBILE ELEVATOR CABINS
20170088399 · 2017-03-30 ·

An elevator system permitting horizontal movement of a normally vertically moving elevator cabin, the elevator cabin being automatically attached to or detached from an elevator frame and horizontally moved to or from another elevator shaft or other destination. While an elevator cabin is supported on an elevator frame or other surface, various cables, rods, plugs and other equipment are automatically connected to or disconnected from the elevator cabin to enable vertical or horizontal motion of the elevator cabin. Once disconnected from such devices, the elevator cabin can be propelled horizontally out of the elevator frame and elevator shaft, onto other surfaces, such as floors of a building, and move horizontally to another destination. An elevator cabin may also be horizontally moved into an elevator shaft and onto the surface of an elevator frame, and connected to the frame, thus enabling such cabin to then move vertically within an elevator shaft.
