20110278098 | METHOD FOR ARRANGING THE REEVING OF AN ELEVATOR, METHOD FOR MODERNIZING AN ELEVATOR, AND ELEVATOR - A method for arranging the reeving of an elevator is provided, which elevator comprises at least an elevator car provided with a car sling comprising an overhead beam, a traction sheave and hoisting roping that passes over the traction sheave, as well as a counterweight and a plurality of diverting pulleys. At least two diverting pulleys are disposed on the roof of the elevator car such that the centers of rotation of the diverting pulleys are above the bottom surface of the overhead beam of the car sling, and the rims of the diverting pulleys are below the bottom surface of the overhead beam of the car sling. | 11-17-2011 |
20110308892 | DIVERTING PULLEY ARRANGEMENT AND ELEVATOR - Diverting pulley arrangement, more particularly a diverting pulley arrangement of an elevator, which includes an axle, at least one diverting pulley that rotates while supported on the axle, a faceplate structure, in relation to which and supported by which the diverting pulley is arranged to rotate on the first side of the faceplate structure, which axle is locked so that it does not rotate in relation to the faceplate structure by the aid of a locking element, which locking element is on the second side of the faceplate structure and supported so that it does not move in relation to the faceplate structure. The locking element is placed against the locking surface included in the axle so that the contact point of the locking element and the locking surface of the axle is at least partly visible. | 12-22-2011 |
20120312640 | ELEVATOR, GUIDE RAIL BRACKET, ARRANGEMENT AND METHOD - Elevator, which includes a guide rail line, which includes a plurality of consecutive guide rails, which are supported on the building with guide rail brackets fixed to the building, which guide rail brackets comprise a frame, a mounting base and structure for pressing the guide rail against the mounting base, which guide rail bracket essentially prevents at its point lateral movement of the guide rail in relation to the fixing point of the guide rail bracket and permits longitudinal movement of the guide rail in relation to the fixing point of the guide rail bracket. The aforementioned mounting base is fixed to the frame of the guide rail bracket movably in the longitudinal direction of the guide rail. | 12-13-2012 |
20130240301 | BACKUP CIRCUIT FOR ELECTRICITY SUPPLY, ELEVATOR SYSTEM, AND METHOD - The invention relates to a backup circuit for electricity supply for ensuring the electricity supply of an electronic overspeed governor in connection with a malfunction of the electricity supply. The backup circuit for electricity supply comprises an energy storage. The backup circuit for electricity supply is configured to disconnect the electricity supply from the energy storage ensuring the electricity supply of the electronic overspeed governor to the overspeed governor when the malfunction of the electricity supply continues. | 09-19-2013 |
20140048359 | ELECTROMAGNETIC BRAKE, A BRAKE, AND A METHOD FOR MAKING A BRAKE - The invention relates to an electromagnetic brake and a method for making an electomagnetic brake. The electromagnetic brake comprises a frame part, an armature part movably mounted on the frame part and having a magnetic core, one or more spring elements for activating the brake by moving the said armature part forwards, an electromagnet fitted to the frame part and arranged to release the brake by pulling the said armature part backwards by resisting the said one or more spring elements, and a planar, elastically bendable damping plate fitted to be bent when the armature part is moving and, while being bent, to produce a damping force resisting the bending to dampen brake noise. | 02-20-2014 |
20140076675 | METHOD AND ARRANGEMENT FOR ADJUSTING A BRAKE - The invention relates to a method and an arrangement for adjusting a brake. The arrangement comprises: a frame part of the brake; a counterpart to be pressed against the frame part; an elastic damping member for damping the noise of the brake, which damping member is configured to form a damping force resisting contact between the countersurfaces of the frame part and of the counterpart, said damping force increasing when the distance between the countersurfaces decreases; and also an adjustment means, for adjusting the damping force formed by the damping member and resisting contact between the countersurfaces of the frame part and of the counterpart. | 03-20-2014 |
20140182974 | METHOD AND AN ARRANGEMENT IN ROPE CONDITION MONITORING OF AN ELEVATOR - The invention relates to a method in rope condition monitoring of an elevator, in which method at least the following steps are performed: electrical resistance between a first point and a second point of elevator suspension and/or transmission ropes is measured first time, a threshold value is determined based on the measurement, the elevator is used for transporting passengers and/or goods, electrical resistance between the first point and the second point of said suspension and/or transmission ropes is measured second time, and results of said second time measurement are compared with said threshold value, and if said second time measurement meets said threshold value, predetermined actions are carried out. The invention also relates to an arrangement in rope condition monitoring of an elevator. | 07-03-2014 |
