An elevator includes a hoistway, an elevator car and a counterweight vertically movable in the hoistway, a drive machine including a drive sheave, a roping including one or more ropes between the elevator car and the counterweight and passing around the drive sheave and suspending the elevator car and the counterweight. The drive sheave is positioned in the hoistway space between a hoistway wall and the vertical projection of the car, the drive sheave rotation plane being at least substantially parallel to the hoistway wall. The rope(s) is/are belt-like, each including at least one force transmission parts for transmitting force in the longitudinal direction of the rope, which force transmission part is made of composite material including reinforcing fibers in a polymer matrix. The reinforcing fibers are carbon fibers, and the force transmission part has width larger than thickness thereof as measured in width-direction of the rope.

The invention relates to an elevator comprising a hoistway, a vertically movable elevator car, a vertically movable counterweight at least one first rope interconnecting the car and counterweight and passing around one or more rope wheels mounted in proximity of the upper end of the hoistway, the weight of the elevator car being arranged to exert an upwards directed pull on the counterweight via said first rope, and the weight of the counterweight being arranged to exert an upwards directed pull on the elevator car via said first rope. The elevator further comprises a motor-driven winding device connected at least with the car or the counterweight for exerting a vertically directed pull on said only one of the car and counterweight for thereby changing the balance between the car and counterweight.

A ropeless elevator system (10) includes a plurality of elevator cars (14) configured to travel in a hoistway having at least one lane (13, 15, 17), a propulsion system (16, 18) to impart force to each elevator car of the plurality of elevator cars, and a controller (46). The controller is configured to operate in an in-group mode where the plurality of elevator cars perform service demands, and to selectively operate in an out-of-group mode where at least one selected elevator car of the plurality of elevator cars performs a predetermined task and is prevented from performing the in-group mode service demands.

An elevator drive for controlling an elevator system has an electric motor with a housing, the electric motor being a permanent magnet synchronous motor. The electric motor has a motor shaft that, on an axial portion of the shaft lateral surface outside the housing, has a drive zone for coupling to at least one support means of the elevator system. A ratio of a weight of the elevator drive to a nominal payload for which the elevator drive is designed is less than 0.2.

An elevator construction arrangement comprises: a first hoistway in a building, a first elevator car, a first counterweight, car guide rails for guiding the first car, and counterweight guide rails for guiding the first counterweight, a first elevator hoisting machine and a first suspension roping arranged to suspend the first elevator car and the first counterweight during construction time use, a protection deck mounted within the first hoistway during a first elevator installation in a bottom section of the first hoistway, a hoist device for hoisting a working platform, the hoist device preferably comprises a man riding hoist attachable to the first car or to an installation platform, and a hoist rope attachable to the first car or the installation platform and movable with the hoist device, and a first hoisting point configured to support the working platform via the hoist device and the hoist rope. During a first elevator installation in the bottom section of the first hoistway the first hoisting point is configured to be mounted to the protection deck and the working platform guided on the car guide rails is configured to be used as an installation platform in the bottom section of the first hoistway, and after the first elevator installation, the first car is in construction time use configured to be moved in the bottom section of the first hoistway by the first elevator hoisting machine which is installed at a top of the bottom section of the first hoistway and supported by the car guide rail, the first elevator hoisting machine suspending the first car and the first counterweight together with the first suspension roping, while the first hoisting point and the hoist device are removed from the first hoistway. A method for installing an elevator during construction of a building.

A method for constructing an elevator includes providing a hoisting machine unit, a guide rail line, an elevator car, a counterweight, and a hoisting roping; using the elevator car for transporting passengers and/or goods while the hoisting machine unit is in a first position; installing one or more guide rail sections into the guide rail line above a guide rail section of the hoisting machine unit; removing the hoisting machine unit from the first position; installing a guide rail section into the guide rail line in place from where the guide rail section of the hoisting machine unit was removed; hoisting the hoisting machine unit; mounting the hoisting machine unit to a second position which is higher than the first position; and using the elevator car for transporting passengers and/or goods while the hoisting machine unit is in the second position. An elevator arrangement is described for implementing the method.

An elevator system may have a vertical shaft and at least two cars that are arranged above one another in the shaft and can each be moved upwards and downwards. A first car may be coupled via first suspension means to a first drive and a first counterweight, and a second car may be coupled via second suspension means to a second drive and to a second counterweight, and to a machine room adjacent to the shaft which is spatially separate from the shaft. The first drive is disposed outside the shaft and the second drive is disposed at least partially within the shaft.

An elevator motor includes a stator with stator windings and a rotor including permanent magnets, whereby the magnets of the rotor and windings of the stator are arranged in an axial flux arrangement. The rotor is connected to a traction sheave for driving hoisting ropes of an elevator, whereby the permanent magnets are arranged on a carrier of the rotor in a ring-like arrangement to form a magnet ring with slots in between. The slot width differs between at least some of two successive slots in the magnet ring. This permanent magnet motor has a reduced noise propagation and is particularly adapted for use in residential elevators.
