The rope comprises a power transmission part (2) or a plurality of power transmission parts (2), for transmitting force in the longitudinal direction of the rope, which power transmission part (2) is essentially fully of non-metallic material.
Abstract:
The invention relates to a monocoque elevator car comprising at least a roof (1), a floor (2) and two side walls (3) assembled from self-supporting elements, in which the monocoque prefabricated structure consists of at least an interior and an exterior face sheet (15, 14) and of filling material (10) placed between the face sheets. The elevator car is additionally provided with a supporting structure (5) to allow the elevator car to be suspended by hoisting ropes (6). According to the invention, at least one of the face sheets (15, 14) forming a side surface of the prefabricated structure preferably has a thickness below 1 mm.
Abstract:
Procedure for operating an elevator, in which the power for moving the car as well as the accelerating/decelerating power of the whole system is, in all motional states of the elevator, obtained from/returned to a hydraulic pressure accumulator (1) charged by an auxiliary gear (3). The elevator machine comprises a hydraulic pressure accumulator (1), hydraulic actuators (2) for adapting the power taken from/fed into the pressure accumulator to the motional state of the elevator car, and an auxiliary gear (3) for pumping hydraulic energy into the pressure accumulator.
Abstract:
The object of the invention is a method for modernizing an elevator, and a traction sheave elevator, which elevator comprises at least an elevator car (1) and a traction sheave (4) that moves the elevator car (1) by means of elevator ropes (3), the rim of which traction sheave comprises one or more rope grooves (8). In connection with modernization a traction sheave is installed as the traction sheave (4) of the elevator, the rope grooves (9) of which traction sheave (4) comprise a material, the frictive traction achieved by which is greater than the frictive traction between the parent material of the metallic traction sheave and the elevator ropes (3).
Abstract:
The object of the invention is a method and an apparatus for lubricating a rope laid from wires in the manufacturing phase of the rope. By means of the invention lubricant, e.g. lubricant (5) containing solid substances such as grease, a grease compound or a paste, is spread onto at least one wire (1) of each strand of the rope to be laid. The lubricant (5) to be spread onto the wire (1) is dispensed onto the endless surface (10) moving in a different direction with respect to the direction of movement of the wire (1) and is conveyed on the aforementioned endless surface (10) into contact with the wire (1).
Abstract:
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.
Abstract:
The object of the invention is a traction sheave elevator and a rope (3) that contains metal as a load-bearing material, such as the suspension rope of an elevator, which rope comprises at least one or more strands (7) laid from metal wires (9) and which rope (3) is lubricated with a lubricant (8). Another object is the use of the aforementioned lubricant for lubricating the rope (3). The lubricant (8) comprises at least oil and thickener, which thickener in the lubricant (8) comprises at least 10% or more of the mass of the lubricant (8).
Abstract:
Rope of a hoisting apparatus, more particularly of a passenger elevator, which comprises a plurality of parts (T1, T2), which continue unbroken for essentially the whole length of the rope, which parts are preferably load-bearing parts. At least one (T2) of the aforementioned parts (T1, T2) is arranged to be essentially more susceptible to breakage in relation to the number of bends than the other (T1) aforementioned parts.
Abstract:
Rope of a hoisting appliance and method for manufacturing rope of a hoisting appliance (1), which rope of a hoisting appliance comprises a core wire (2) or similar and a plurality of outer wire layers, each of which comprises a plurality of wires (3). The rope (1) comprises at least one such wire layer, essentially all the wires (3) of which are at essentially the same distance from the core wire (2) and contain composite material and of which at least a part are essentially wedge-shaped in the shape of their cross-section. The hoisting appliance rope (1) can comprise at least one such wire layer that comprises wire bundles essentially at the same distance from the longitudinal axis of the rope and which wire bundles comprise wires (3) comprised of composite, and at least a part of which wire bundles are essentially wedge-shaped in the shape of their cross-section. In the method a plurality of wires (3) are directed into at least one outer layer (L) as a part of the rope (1) such that at least a part of the wires (3) forming the rope (1) are composite and in the method at least a part of the composite wires (3) intended to be a part of the rope (1) are coated with polymer and the wires (3) are directed into the proximity of each other as a part of the rope (1).
