| 20080264729 | Elevator and elevator brake - The invention relates to an elevator and an elevator brake, which elevator contains at least a hoisting machine ( | 10-30-2008 |
| 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 |
| 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 |
| 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 |
