PROBLEM TO BE SOLVED: To improve a structure and a manufacturing technology of a complex structural rope of a lift.SOLUTION: This invention particularly relates to a rope (R) of a passenger transporting elevator and/or a cargo transporting elevator, the elevator, and a manufacturing method of the rope. The rope has a continuous load support part (P), its profile is substantially rectangular, the width of a cross section is larger than its thickness, and the load support part contains, in a polymer matrix material, a glass fiber reinforced material and/or an aramid fiber reinforced material and/or a carbon fiber reinforced material and/or a polybenzoxazole fiber reinforced material and/or a polyethylene fiber reinforced material, and/or a nylon fiber reinforced material. A long-side face of the cross section of the load support part (P) has one or more grooves (G) which are symmetric or asymmetic with respect to the longitudinal direction of the rope, and the groove (G) divides the load support part (P) into small portions (P1, P2, ...., PM).
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:
The object of the invention is an elevator arrangement comprising independently moving elevator cars (6) in the same elevator hoistway (1a, 1b), which elevator arrangement comprises one or more elevator hoisting machines (2) with traction sheave (2a) and a traction means (4) transmitting moving force from the traction sheave (2a) to the elevator cars (6). The elevator arrangement according to the invention is characterized in that one and the same traction means (4) is adapted to transmit the moving force produced by one or more hoisting machines (2) to all the elevator cars (6) of the elevator arrangement. A coupling arrangement is used in the elevator arrangement, in which coupling arrangement the toothed belts transmitting moving force to the elevator cars (6) are provided with magnets and ferromagnetic metallic elements for achieving reliable tooth contact.
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:
People mover (1), more particularly a travelator or corresponding, which comprises a plurality of steps or corresponding for carrying and moving people, a transmission chain formed into an endless loop, which transmission chain is connected to the aforementioned steps or corresponding, and via which transmission chain the steps or corresponding are moved, and which transmission chain comprises consecutive chain links, which are connected in a hinged manner to each other such that the chain links are able to bend in relation to each other in a first direction (I) and in a second direction (II), and which' transmission chain is arranged to pass around at least two turning elements (5,6), when passing around which the consecutive chain links of the transmission chain bend in relation to each other in the first direction. The transmission chain comprises means for limiting bending of the transmission chain occurring in the second direction (II).
Abstract:
A hoisting machine rope (10), which has a width larger than its thickness in a transverse direction of the rope, which comprises a load-bearing part (11) made of a composite material, said composite material comprising non-metallic reinforcing fibers, which consist of carbon fiber or glass fiber, in a polymer matrix. An elevator, which comprises a drive sheave, an elevator car and a rope system for moving the elevator car by means of the drive sheave, said rope system comprising at least one rope whose width (t2) is larger than its thickness (tl) in a transverse direction of the rope, and the rope comprises a load- bearing part (11) made of a composite material, said composite material comprising reinforcing fibers in a polymer matrix.
Abstract:
The present invention relates to a drive system for an elevator. The elevator comprises a drive machine (2, 4) by means of which the elevator car (6) can be moved and supported. The primary circuit (2) of a linear motor is permanently fitted to a wall of the building while its secondary circuit is fitted in conjunction with the elevator car (6) and moves with the elevator car (6). Pressurised air is supplied between the primary (2) and secondary (4) circuits of the reluctance-type linear motor to maintain an air gap (20) between them.
