A damper unit for an elevator, for the purpose of reducing vertical vibration of a stopping elevator car, has at least one roller that, in an active position, is in contact with a guide rail for the elevator car and can be rotated about an axis of rotation. For damping rotary movements during vertical vibration of the stopping elevator car, the roller is connected to a rotation damper.

Disclosed is a fall prevention brake buffering system for high-speed mine lift, including brake ropes (2) fixed on two sides of a car (5). One end of the brake rope (2) is fixed on the top part of a vertical well (6), and the other end is fixed on the bottom part of the vertical well (6). A linkage mechanism (11) is arranged at the bottom of the car (5). A buffer (1) is arranged at the top of the brake rope (2), and a tension connector (4) is arranged at the bottom of the brake rope (2). A brake rope safety tong (3) fixed on the brake rope (2) and connected with the linkage mechanism (11) is arranged at the bottom of the car (5). The buffer (1) includes an inverted brake rope gradual safety tong (8) with a buffering rope (9) provided therein and connected with the brake rope (2). A buffering rope clip (10) is arranged on the buffering rope (9). The system is convenient to install, and the buffering force of the brake rope is constant and adjustable. The system realizes reliable fall prevention brake function, greatly improves safety performance during high-speed operation of a lift with non-rigid rails, and increases safety performance during high-speed operation of a mine lift.

An elevator installation has a car at least partially supported by a support including several electrically conductive tension-bearing elements, which elements are arranged parallel to each other and which are substantially surrounded by a jacket. The support is fastened to fastening devices, wherein the fastening devices each include a housing and a clamping element. The housing and the clamping element each have clamping surfaces, between which surfaces the support is clamped. An electrically insulating material is arranged between at least one side of the support and the clamping surfaces arranged thereon. The electrically insulating material electrically isolates the support from the housing or the clamping element or both.

A rope terminal assembly of an elevator fixes an elevator rope to a fixing base such as an elevator unit, said elevator being suitable for transporting passengers and/or goods, which assembly includes at least the following components: an elevator rope, whose width is larger than its thickness in a rope transverse direction, with at least one end having an end face, one or more wedge elements, and a wedge housing, the rope terminal assembly including a rope gap through which said elevator rope passes and said wedge element is arranged to wedge between said rope and said wedge housing thus locking said elevator rope in the gap, and at least one component of the rope terminal assembly made of fiber reinforced polymer composite material, and an elevator.

An elevator system (20) load bearing assembly (30) includes a plurality of load bearing members (32-38). At least one of the load bearing members (32-38) has a load carrying capacity that is different than at least one other of the load bearing members (32-38). A disclosed example includes equal numbers of load bearing members (32, 38) having a first load carrying capacity and equal numbers of load bearing members (34, 36) having a second, different load carrying capacities. Another example includes at least three different load carrying capacities. With the disclosed examples, the aggregate load carrying capacity of an elevator load bearing assembly (30) can more closely meet the load carrying requirements for a given elevator system without over-roping the system.

The invention relates to a rope terminal device for fixing rope ends of ropes of an elevator, comprising a rope terminal body comprising one or more cavities for accommodating one or more rope ends; one or more fixing members for fixing the one or more rope ends immovably into the one or more cavities; wherein the rope terminal body is a metallic block surrounding said one or more cavities, and weighs more than 200 kg, the rope terminal body providing thermal mass around the one or more rope cavities for delaying heat transfer from the exterior to the rope ends contained in the one or more cavities. The invention relates to a rope terminal arrangement and an elevator implementing said rope terminal device.

A method for detecting a deterioration state in an elevator suspension member including electrically conductive cords uses a multiplexing unit (MU) to apply first and second alternating voltages to proximal ends of first and second groups of the cords respectively and connect the proximal end of a third group of the cords to a voltage measurement arrangement connected to a reference potential. Distal ends of the groups are connected together. A first neutral point voltage between the third proximal end and the reference potential is determined. The MU is switched to apply the first alternating voltage to the second proximal end, apply the second alternating voltage to the third proximal end and determine a second neutral point voltage between the first proximal end and the reference potential. The deterioration state of the suspension member arrangement is determined based on the first and second neutral point voltages.

A method for roping an elevator. At the bottom part of the elevator shaft the hoisting ropes are routed under the pulleys of the elevator car. Then the elevator car and the counterweight are hoisted to the upper part of the shaft where the first ends of the hoisting ropes are routed through the traction sheave and the counterweight pulleys. After that the first rope ends are fixed to the counterweight side rope terminals and the counterweight is lowered to the bottom part of the shaft. During the descent the hoisting ropes are unwound from the reels through the whole roping system with the help of the mass of the counterweight. Finally, the second ends of the hoisting ropes are fixed to the car side rope terminal and tightened to the correct tension.
