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.

A counterweight is provided including a counterweight frame including a crosshead. A counterweight hitch is operably coupled to the counterweight frame. The counterweight hitch includes a vertically stacked first sheave channel and a second sheave channel. Each of the first sheave channel and second sheave channel includes an interior cavity within which at least one individual sheave assembly is mounted. The plurality of individual sheave assemblies is substantially identical and arranged at an angle relative to a central plane of the counterweight frame.

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 suspension member for suspending and/or driving an elevator car of an elevator system includes a plurality of tension members extending along a length of the suspension member including a plurality of fibers extending along the length of the suspension member bonded into a polymer matrix. A jacket substantially retains the plurality of tension members. The suspension member is configured to be deformed at a suspension member end to allow for installation of the suspension member end into a termination assembly of the elevator system. A method of installing a suspension member of an elevator system into a termination assembly includes deforming a suspension member end and reforming it to a selected shape, inserting the suspension member end into the termination assembly and curing and/or hardening it, and applying a load thereto or to the socket or the wedge to secure the suspension member end in the termination assembly.

The invention relates to rope gripping member for a rope gripping device, the rope gripping member comprising an elongated rope gripping face for being pressed against an elongated side face of an end section of a rope, the elongated rope gripping face having a longitudinal direction and a front edge and a rear edge; wherein tensile stiffness of the rope gripping member in longitudinal direction of the gripping face increases non-linearly with accelerating rate from the front edge towards the rear edge of the gripping face. The invention also relates to a rope gripping device, a rope terminal arrangement and a hoisting apparatus implementing the rope gripping member.
