In a machine-room-less elevator, a hoisting machine is disposed directly above a counterweight. A counterweight speed governor is disposed higher than a position of the counterweight if a car descends to a floor portion of a hoistway and the counterweight jumps upward. When viewed from directly above, at least a portion of the counterweight speed governor is disposed at an identical position to a first counterweight guide rail in a width direction of the counterweight, and is disposed at an identical position to a portion of a suspending body between a driving sheave and a counterweight suspending sheave in a direction that is perpendicular to the width direction of the counterweight.

An elevator system has an elevator car that can travel vertically along a vertical track including a stationary vertical guide rail, and that can travel horizontally by a car transfer device. The car transfer device has a horizontal displacement unit with a vertical guide rail piece that guides the elevator car in the horizontal displacement unit, the horizontal displacement unit being movable into a transit position in which the guide rail piece and the stationary vertical guide rail together form a section of the vertical track. The elevator system has a connecting device by which, in the transit position of the horizontal displacement unit, the vertical guide rail piece can be connected to the stationary vertical guide rail, wherein, when connected by the connecting device, the vertical guide rail piece cannot be displaced in the horizontal direction with respect to the stationary vertical guide rail.

An elevator system including a hoistway, an elevator component disposed in the hoistway, and a power assembly disposed in the hoistway, the power assembly including a first power component disposed in the hoistway, the first power component comprising a first power connection, and a second power component operably coupled to the elevator component; wherein the first power component is configured to provide wireless power to the second power component.

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.

In a method for carrying out an installation process in an elevator shaft of an elevator system, an assembly device is inserted into the elevator shaft. The assembly device includes a support component, a mechatronic installation component retained by the support component and a control apparatus. At least one assembly apparatus (tool, sensor or component) is arranged on the support component. The support component is fixed in a fixing position in the elevator shaft. After the support component has been fixed, an actual position of the at least one assembly apparatus is determined relative to the installation component. Using the determined actual position relative to the support component, the at least one assembly apparatus is received by the installation component and an assembly step is carried out using the received at least one assembly apparatus.

An elevator system includes a first lane oriented in a first direction, a second lane oriented in a second direction, a car configured to travel in the first and second lanes, a repositioning unit configured to reposition the car from the first lane to the second lane and from the second lane to the first lane, and a plurality of guide rails disposed in each of the first and second lanes that are configured to guide the car along each of the first lane and the second lane. The plurality of guide rails includes a plurality of rucksack guide rails configured to guide the car when it is at least one of already on the repositioning unit, entering the repositioning unit, or exiting the repositioning unit, and a plurality of lateral guide rails configured to guide the car when it is not in the repositioning unit.

An exemplary vertically moveable elevator system component includes a top portion, a bottom portion and a plurality of vertically oriented side portions between the top and bottom portions. At least one of the side portions includes a roller guide support sheet. A first roller guide roller is supported by the sheet such that the first roller is at least partially disposed on a first side of the sheet and an axis of the first roller is generally parallel with the sheet. Second and third rollers are supported by the sheet such that the second and third rollers are on a second, oppositely facing side of the sheet. An axis of each of the second and third rollers is generally perpendicular to the axis of the first roller. The axis of each of the second and third roller remains in a fixed position relative to the sheet.
