An elevator system includes an elevator car. A first drive assembly engages a first tension member. The first tension member is coupled to the elevator car and to a first counterweight. A second drive assembly engages a second tension member. The second tension member is coupled to the elevator car and to a second counterweight. The first tension member can be coupled to the elevator car at a first position and the second tension member can be coupled to the elevator car at a second position opposite the first position.

An elevator includes a hoistway; an elevator car vertically movable in the hoistway, the passage to and/or from the elevator car being provided in depth direction of the hoistway; a counterweight vertically movable in the hoistway beside the elevator car in width direction of the hoistway; one or more ropes interconnecting the elevator car and the counterweight and hanging from these; a rope wheel arrangement in the bottom end of the hoistway for guiding the one or more ropes; and a vertically oriented guide rail for guiding the elevator car extending between the elevator car and counterweight. The elevator includes a bridge structure mounted on the floor of the hoistway, the bridge structure including a cross member, wherein the guide rail for guiding the elevator car is mounted on top of the cross member, the bridge structure including a passage for the one or more ropes below the cross member, and the one or more ropes pass from the counterweight downwards to the rope wheel arrangement, and the rope wheel arrangement is arranged to guide the one or more ropes to pass below the cross member via said passage and up to the elevator car.

A method and a monitoring device determine a wear state of components such as a cable-like suspension means, a traction sheave of a drive machine and deflection rollers of a suspension means arrangement of an elevator system. The method comprises at least the following steps: monitoring an actual time curve of a first parameter which correlates with the wear state of at least one first monitored component of the components; comparing the actual time curve of the monitored first parameter with a predetermined expected time curve of the first parameter; and determining the wear state of the monitored component based on a result of the comparison.

An elevator system includes at least one car and at least one counterweight. At least two support means having different physical properties are arranged between the at least one car and the at least one counterweight.

A drive system for an elevator installation includes a drive and a drive suspension for fastening the drive to a support element of the elevator installation. The drive suspension includes a rotary joint for tiltably mounting the drive on the support element and an adjustment device for setting a tilt of the drive about the rotary joint. The support element can be a guide rail wherein the drive system is arranged in an upper end region of the elevator installation.

An elevator apparatus includes: a traction machine including a sheave around which a middle portion of a main rope from which a car and counterweight are suspended is wound; a controller configured to control travel of the car; a section specification unit configured to specify a determination target section serving as a travel section, including at least a travel position of the car, satisfying a predetermined determination execution condition; a sheave rotation detector configured to detect a sheave rotation amount; and a determinator configured to determine traction performance of the sheave based on the sheave rotation amount detected during travel of the car in the determination target section. The determination execution condition is to have a load weight and an acceleration of the car that cause direction of an acceleration vector of one of a car side and a counterweight side heavier than the other to match an ascent direction.

An elevator system (100) includes an elevator car (102). A first drive assembly (160) engages a first tension member (112). The first tension member (112) is coupled to the elevator car (102) and to a first counter-weight (104). A second drive assembly (170) engages a second tension member (122). The second tension member (122) is coupled to the elevator car (102) and to a second counterweight (106). The first tension member (112) can be coupled to the elevator car (102) at a first position (110) and the second tension member (122) can be coupled to the elevator car (102) at a second position (120) opposite the first position (110).

An elevator system and a support column assembly. The elevator system includes a support column, with the bottom end thereof connected to a bottom mounting base, and the top end thereof connected to a top mounting base; a counterweight arranged in the support column; a car having a through hole penetrating in a vertical direction, wherein the car is arranged around the support column via the through hole; and a traction assembly, wherein the car is connected to the counterweight via the traction assembly, and the car and the counterweight reciprocate along the length direction of the support column under the traction of the traction assembly.

A rope for a hoisting device, which rope is belt-shaped and includes several load bearing members spaced apart in the width direction of the belt-shaped rope and embedded in a common coating, each of the load bearing members including several load bearing strings twisted together. The load bearing strings are made of composite material including reinforcing fibers embedded in polymer matrix.

An elevator system and a support column assembly. The elevator system includes a support column, with the bottom end thereof connected to a bottom mounting base, and the top end thereof connected to a top mounting base; a counterweight arranged in the support column; a car having a through hole penetrating in a vertical direction, wherein the car is arranged around the support column via the through hole; and a traction assembly, wherein the car is connected to the counterweight via the traction assembly, and the car and the counterweight reciprocate along the length direction of the support column under the traction of the traction assembly.
