20110266097 | ELEVATOR - Elevator, preferably a passenger elevator, which comprises an elevator car, and at least one hoisting rope for moving and supporting the elevator car, a traction sheave that acts on the hoisting rope, and a power source for rotating the traction sheave. The counterweight of the elevator comprises a brake for decelerating and/or preventing at least upward movement of the counterweight. | 11-03-2011 |
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 |
20140299419 | ELEVATOR - The invention refers to an elevator comprising an elevator car and a suspension arrangement for suspending and/or moving an elevator car, which suspension arrangement comprises at least one suspension member, whereby at least one suspension member component is provided which component is to be applied to the suspension member for affecting the physical properties of the suspension member during the operation of the elevator. According to the invention the suspension member component applied to the suspension member comprises an component identifier which is an addition to the suspension member component which component identifier is configured to be identified visibly or via additional tools. The invention allows the unambiguous identification of the suspension member component and also the distribution of the component on the suspension member surface. | 10-09-2014 |
20140305744 | ROPE OF A LIFTING DEVICE, A ROPE ARRANGEMENT, AN ELEVATOR AND A CONDITION MONITORING METHOD FOR THE ROPE OF A LIFTING DEVICE - In a rope of a lifting device, particularly of a passenger transport elevator and/or freight transport elevator, the width of which rope is greater than the thickness in the transverse direction of the rope, which rope includes a load-bearing part in the longitudinal direction of the rope, which load-bearing part includes carbon-fiber reinforced, aramid-fiber reinforced and/or glass-fiber reinforced composite material in a polymer matrix, and which rope includes one or more optical fibers and/or fiber bundles in connection with the load-bearing part and the optical fiber and/or fiber bundle is laminated inside the load-bearing part and/or the optical fiber and/or fiber bundle is glued onto the surface of the load-bearing part and/or and that the optical fiber and/or fiber bundle is embedded or glued into the polymer envelope surrounding the load-bearing part, as well as to a condition monitoring method for the rope of a lifting device. | 10-16-2014 |
20150060588 | ROPE STORAGE UNIT, A METHOD FOR INSTALLING ELEVATOR AND A METHOD FOR FABRICATING ROPE STORAGE UNIT - A rope storage unit includes a rope reel, formed by a rope wound in a spiral form and a support body provided with an inner space inside which the rope reel is positioned supported by the support body. The rope is a rod having a straight form when in rest state and elastically bendable away from the straight form, the rope being under substantial bending tension in the spiral form. The support body includes one or more support members delimiting the inner space and surrounding radially the rope reel. The outer rim of the rope reel radially compresses against the one or more support members as an effect of the bending tension. A method is provided for installing an elevator rope implementing the rope storage unit, as well as to a method for fabricating the rope storage unit. | 03-05-2015 |
20150129367 | METHOD FOR CONDITION MONITORING OF ELEVATOR ROPES AND ARRANGEMENT FOR THE SAME - A method is provided for condition monitoring of a rope of an elevator including an elevator car and a rope wheel arrangement, which rope is connected to the elevator car and passes around at least one rope wheel included in the rope wheel arrangement. The method includes obtaining travel data of the elevator car, the travel data including information describing occurrence(s) of car start(s) and/or bypass(es); and determining based on the travel data a total number of car visits at a predetermined landing in the path of the elevator car, which total number is the sum of the number of starts of the elevator car away from said predetermined landing so as to travel to any other landing irrespective of the traveling direction, and the number of times the elevator car has bypassed said predetermined landing without stopping irrespective of the traveling direction; and comparing the total number or a multifold of the total number with a first predetermined limit value, wherein said multifold equals to the total number multiplied with factor n wherein n equals the number of said at least one rope wheel; and performing one or more predetermined action if said total number or the multifold of the total number meets the first predetermined limit value, said one or more action including one or more of indicating a weakened rope condition, indicating a need for maintenance or replacement of elevator rope(s), calculating an estimated moment of maintenance or replacement of elevator rope(s), sending a specific or general warning signal, sending a fault signal, sending a signal to a service center the signal indicating weakened rope condition or a need for maintenance or a need for replacement of elevator rope(s). An arrangement implements the method. | 05-14-2015 |
20150232302 | ELEVATOR - A rope clamp for clamping one or more ropes includes a first clamping member having a first clamping face for being set against one or more ropes to be clamped and a second clamping member having a second clamping face for being set against one or more ropes to be clamped. The clamping faces defining a gap (between them) for receiving one or more ropes. The clamping members are relatively movable towards each other such that the gap is narrowed. The first clamping member and/or the second clamping member includes a metallic face part forming the clamping face of the clamping member, a metallic body part on the back side of the face part, and an elastic intermediate part made of elastic material between the body part and the face part for elastically transmitting force between the body part and the face part. | 08-20-2015 |
