An elevator includes an elevator car and a counterweight; a first roping between the elevator car and counterweight and including at least one rope; a second roping between the elevator car and counterweight and including at least one rope; and a rope wheel arrangement, having at least one rope wheel, around which the at least one rope of the second roping passes. The longitudinal force transmission capability of the at least one rope of the second roping is based essentially on non-metallic fibers and is a belt-like rope having at least one contoured side provided with guide rib(s) and/or guide groove(s) oriented in the longitudinal direction of the rope, the side being fitted to pass against a contoured circumference of a rope wheel of the rope wheel arrangement, the circumference being provided with guide rib(s) and/or guide groove(s) so as to form a counterpart for the contoured side of the rope.
摘要:
A rope of a lifting device, more particularly of a passenger transport elevator and/or freight transport elevator, an elevator, and a method for manufacturing the rope are disclosed. The rope includes an unbroken load-bearing part, the profile of which is essentially of rectangular shape, and the width of the cross-section is greater than the thickness and which load-bearing part comprises glass fiber reinforcements and/or aramid fiber reinforcements and/or carbon fiber reinforcements and/or polybenzoxazole fiber reinforcements and/or polyethylene fiber reinforcements and/or nylon fiber reinforcements in a polymer matrix material. The long sides of the cross-section of the load-bearing part include one or more grooves symmetrically or asymmetrically in the longitudinal direction of the rope, which grooves divide the load-bearing part into smaller parts.

摘要:
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.

摘要:
In a paste type lubrication between a steel wire rope and a rope groove of a pulley, is applied a paste lubricant which contains oil and small solid particles. Solid particles could be of a wide variety sizes and they are small enough to at least partly fit into the valleys between the peaks of surface roughness of the ropes or the rope groove.
摘要:
A wire rope is disclosed that comprises metal wires, preferably steel wires, as a load-bearing material, which rope comprises at least one or more strands laid from said metal wires and which rope is lubricated with a lubricant. Another object is the use of the aforementioned lubricant for lubricating a steel rope. The lubricant comprises at least oil and powder substance, which powder substance comprises at least particles whose hardness is greater than 4 on the Mohs scale.A traction sheave elevator comprising such a wire rope as a suspension rope is disclosed, too.
