According to the invention, the elevator system comprises at least one elevator without counterweight for moving people and/or goods, which elevator without counterweight comprises a power converter unit, an elevator motor, a traction sheave, a set of hoisting ropes and an elevator car, and which elevator system comprises means for storing mechanical energy and discharging an energy storage. | 11-20-2008 |
| 20080296125 | Load sharing handrail drive apparatus - A handrail drive apparatus is provided comprising a first drive wheel assembly configured to drive a handrail and comprising a planetary gear train arranged to be driven by a first driving member. The handrail drive apparatus further comprises a second drive wheel assembly configured to drive the handrail, the second drive wheel assembly being coupled to the planetary gear train of the first handrail drive wheel assembly by a second driving member. The planetary gear train of the first handrail drive wheel assembly is configured to divide a torque imparted by the first driving member between the first and second drive wheel assemblies. | 12-04-2008 |
| 20080314691 | Elevator traction sheave and elevator - In the elevator of the invention, the hoisting rope is roped to meet the traction sheave in two different rope grooves, which have differ from each other in respect of their holding properties. In the traction sheave of the invention, at least two adjacent rope grooves have cross-sectional shapes differing from each other. | 12-25-2008 |
| 20090050414 | Arrangement for equalizing elevator rope force and elevator - The invention relates to an arrangement for equalizing the rope force of a traction sheave elevator, said elevator comprising at least a hoisting machine ( | 02-26-2009 |
| 20090050443 | Travelator, moving ramp or escalator - A travelator, moving ramp or escalator for transporting passengers, comprises a conveyor mounted on a frame that is supported on a fixed structure. The frame comprises a number of mutually identical profiled metallic bodies joined together end to end one after the other and containing coupling, supporting and/or guide elements integrated in the profiled metallic body of solid material. | 02-26-2009 |
| 20090120733 | ARRANGEMENT IN AN ELEVATOR WITHOUT COUNTERWEIGHT - The present invention relates to an arrangement in an elevator without counterweight, which comprises at least a control unit ( | 05-14-2009 |
| 20090139831 | ARRANGEMENT IN THE DRIVE MACHINERY OF A TRAVELATOR, METHOD FOR CHANGING THE DRIVE BELT OF THE HANDRAIL BELT OF THE HANDRAIL OF A TRAVELATOR, AND SUPPORT ELEMENT OF THE HANDRAIL BELT OF THE HANDRAIL OF A TRAVELATOR - An arrangement in drive machinery of a travelator, moving walkway, escalator or similar apparatus, includes at least a drive motor, at least one handrail with a handrail belt, a support element supporting the handrail and a drive belt connecting rotational movement of the drive motor to the support element. The support element comprises a supporting wheel, having a rim and adapted for use by the drive belt which is fitted to the rim of the support element. | 06-04-2009 |
| 20090229923 | Traction sheave elevator without counterweight - The subject of the invention is a traction sheave elevator without counterweight, which comprises at least a drive machine with traction sheave, hoisting ropes, an elevator car guided on its track or the like, car guide rails on one side of the elevator car, which is supported on the hoisting ropes such that the hoisting ropes are on one side of the elevator car. The elevator contains a plurality of rope pulley modules, which comprise a plurality of diverting pulleys. | 09-17-2009 |
| 20090250298 | Elevator group and method for controlling an elevator group - A set of elevators, e.g. an elevator group, is connected to a common power supply. The elevators are controlled by a common control system so that an elevator car having stopped is prevented from being dispatched in the up direction if, of the elevator cars of the elevators connected to the common power supply, more cars are moving upwards than are moving downwards. | 10-08-2009 |
| 20100200337 | Elevator - Elevator, preferably an elevator without machine room. In the elevator, a hoisting machine engages a set of hoisting ropes by means of a traction sheave. The set of hoisting ropes comprises hoisting ropes of substantially circular cross-section. The hoisting ropes support a counterweight and an elevator car moving on their respective tracks. The hoisting rope has a thickness below 8 mm and/or the diameter of the traction sheave is smaller than 320 mm. The contact angle between the hoisting rope or hoisting ropes and the traction sheave is larger than 180°. | 08-12-2010 |
| 20100219023 | ELEVATOR - The invention relates to an elevator provided with a safety gear arrangement, the elevator including at least an elevator car arranged to travel back and forth substantially vertically along guide rails, at least two safety gear mechanisms disposed in conjunction with the elevator car and at least one speed limiter, which includes at least a speed limiter pulley, a diverting pulley and a speed limiter rope fitted as a loop around at least the speed limiter pulley and the diverting pulley, the speed limiter rope being connected at least to a first safety gear mechanism. A second safety gear mechanism has been arranged to be triggered after the triggering of the first safety gear mechanism. | 09-02-2010 |
| 20110017551 | Elevator - An elevator may include an elevator car, a set of hoisting ropes, a traction sheave, and a compensating device. The set of hoisting ropes may include first and second rope portions. The elevator car may include one or more first diverting pulleys from which the first rope portions extend upward. The elevator car may include one or more second diverting pulleys from which the second rope portions extend downward. The first rope portions may be under a first rope tension. The second rope portions may be under a second rope tension that is different from the first rope tension. The compensating device may act in substantially opposite directions on the first and second rope portions. The compensating device may produce an auxiliary force acting substantially in a same direction as the first rope tension. | 01-27-2011 |
