The method includes at least the following phases: a double bearing is formed by disposing two bearings next to each other side-by-side and by placing a separator that forms a gap between the bearings such that the separator rests on at least one of outer surface of the outer rim of a bearing, and the separator part of the separator is disposed between the side surfaces that face each other of the outer rims of the bearings; the formed double bearing is placed in the casting mold in the correct position; and the casting is cast around the double bearing | 06-06-2013 |
20130133987 | ELECTRICITY SUPPLY APPARATUS AND AN ELEVATOR SYSTEM - The invention relates to an electricity supply apparatus, an elevator system and a method for limiting the electricity consumption of an elevator system. The electricity supply apparatus according to the invention is fitted to supply electricity to one or more devices in an elevator system. The minimum value of the permitted supply voltage with which the apparatus still operates is determined for one or more appliances of the elevator system, and the electricity supply apparatus is equipped to change the supply voltage of the one or more appliances of the elevator system towards the minimum value of the permitted supply voltage for limiting electricity consumption of the elevator system. | 05-30-2013 |
20130133986 | PASSENGER FLOW MANAGEMENT SYSTEM - A passenger flow management system can manage passenger flow such that elevator waiting times may be limited. The management system includes a detector configured to detect elevator passengers within a detection area located outside the building. | 05-30-2013 |
20130126278 | SLIDING GUIDE SHOE AND AN ELEVATOR PROVIDED WITH A SLIDING GUIDE SHOE - A sliding guide shoe includes at least a body part, which includes at least a slide pad space for a slide pad as well as at least one fixing part for fixing the sliding guide shoe to its base. The body part is essentially the same in its cross-sectional profile throughout its whole length. An elevator is also provided with the sliding guide shoe. | 05-23-2013 |
20130118840 | COMPENSATION DEVICE AND ELEVATOR - A compensation device of a traction sheave elevator is provided. The elevator includes a compensation rope running from an elevator car to a compensation sheave of the compensation device located in the lowermost part of the elevator shaft around which the compensation rope runs. The compensation sheave is vertically guided with respect to the shaft bottom via a guiding structure, which allows a vertical movement of the axis of the compensation sheave. The guiding structure includes at least one scissor joint arrangement having its lower end adapted to be connected with an elevator shaft bottom and its upper end being connected with the compensation sheave axis. An elevator includes such kind of compensation device. Vertical movement of the axis of a compensation sheave can be obtained with a very low shaft height requirement. | 05-16-2013 |
20130118838 | METHOD AND ELEVATOR ARRANGEMENT - A method of manufacturing an elevator includes installing a movable supporting platform and an elevator car in the elevator hoistway; taking the elevator car into use to serve passengers and/or to transport goods; removing the elevator car from use; changing the service range of the elevator car to reach higher up in the elevator hoistway by lifting the supporting platform higher up in the elevator hoistway; and taking the elevator car back into use. The elevator is reeved to include construction-time hoisting roping, which includes one or more ropes, the longitudinal power transmission capacity of which is based at least essentially on non-metallic fibers in the longitudinal direction of the rope. In the method, guide rails to be fixed with guide rail brackets can additionally be installed by the aid of an installation device. An elevator arrangement can be used to perform the method. | 05-16-2013 |
20130111723 | METHOD FOR INSTALLING THE HOISTING ROPING OF AN ELEVATOR - Method for installing the hoisting roping of an elevator, wherein the first elevator unit to be moved is disposed at a suitable point in the elevator hoistway, and the second elevator unit to be moved is disposed at a suitable point in the elevator hoistway, which first elevator unit is an elevator car and which second elevator unit is a counterweight, or vice versa. The first and/or second section of the hoisting roping is connected to its elevator unit via a diverting pulley system such that when the diverting pulley system is still separate from the elevator unit, the section in question of the hoisting roping is arranged to travel under the diverting pulley system of its elevator unit, and the diverting pulley system is lowered, when reeved, downwards into the proximity of its elevator unit, after which the diverting pulley system in question is fixed to its elevator unit. | 05-09-2013 |
20130075200 | ELEVATOR SYSTEM - An elevator system includes an elevator car and also a motor drive for moving the elevator car according to a movement profile to be determined for the movement of the elevator car. The loading of the motor drive is arranged to be limited to the limit value for the maximum permitted loading by changing the value of a movement magnitude of the elevator car in the movement profile of the elevator car when the position of the elevator car changes. | 03-28-2013 |
20130056310 | GUIDE RAIL OF AN ELEVATOR, AND AN ELEVATOR - Guide rail of an elevator, for guiding an elevator car and/or the counterweight of an elevator, which guide rail comprises an elongated metal profile piece that continues essentially the same in its cross-sectional shape, which metal profile piece comprises a continuous inside space for at least essentially the whole length of the guide rail. | 03-07-2013 |
20130048432 | ELEVATOR - Elevator, which includes at least an elevator car and a device for moving the elevator car, preferably along guide rails, and a counterweight, and one or more ropes, which rope connects the elevator car and the counterweight and is separate from the supporting function and passes around a diverting pulley mounted on the bottom end of the elevator hoistway. The rope comprises a power transmission part or a plurality of power transmission parts, for transmitting power in the longitudinal direction of the rope, which power transmission part is essentially fully of non-metallic material. | 02-28-2013 |
20130025977 | HOISTING MACHINE INCLUDING A MEASURING ARRANGEMENT AND ELEVATOR SYSTEM CONTAINING THE SAME - A measuring arrangement for the measurement of the position and/or movement of a rotor of an electricmachine, an electric drive including the measuring arrangement, and an elevator system including the electric drive are provided.
