摘要： An elevator system is provided including a hoistway having a plurality of landings. An elevator car is configured to move within the hoistway between the plurality of landings. A plurality of guide rails guide movement of the elevator car and a counterweight within the hoistway. Each guide rail includes a base and a blade. A machine assembly is mounted within the hoistway and includes a traction sheave rotatable about an axis. The traction sheave is configured to drive movement of the elevator car between the plurality of landings. At least one of the plurality of guide rails is arranged in an overlapping configuration with the machine assembly such that a plane defined by the base of the guide rail is parallel to the axis and intersects a portion of the traction sheave.

摘要： An elevator system includes a hoistway and an elevator car (12) suspended in the hoistway via one or more suspension members (46). A counterweight (22) is suspended in the hoistway via the one or more suspension members (46) to balance operation of the elevator car (12). A traction sheave (24) is located in the hoistway to drive the one or more suspension members (46) along the hoistway via traction with frictional contact between the traction sheave (24) and the one or more suspension members (46), thus driving motion of the elevator car (12) and/or counterweight (22) along the hoistway. One or more diverters (66) are positioned in the hoistway in operable contact with the one or more diverters (66). The one or more diverters (46) are configured and positioned to define a wrap angle (68) of the one or more diverters (66) about the traction sheave (24); the wrap angle (68) being between 180 degrees and 360 degrees.

摘要： A method of operating an elevator system (10) includes identifying one or more components (46, 48, 50, 52) in an elevator hoistway (14) requiring periodic maintenance and/or inspection and programming hoistway component locations of the one or more components into an elevator car control system. The elevator car (12) is driven to a programmed hoistway component location of a selected component of the one or more components utilizing the hoistway component location programmed into the elevator car control system. The selected component is accessed from inside the elevator car (12) to perform maintenance and/or inspection of the selected component.

摘要： A device for limiting sway in a travelling cable (6) in an elevator system is provided. The device comprises: a channel extending in a first direction for receiving the travelling cable (6) therein, wherein the channel is configured to be mounted in an elevator hoistway (2) such that the first direction corresponds to a direction of motion of an elevator car (4) within the hoistway (2); and an element (20) configured to move in the first direction along an open side of the channel simultaneously with an elevator car (4) and to push the travelling cable (6) into the channel when the element (20) moves along the open side thereof.

摘要： An elevator car for an elevator system includes a floor and one or more elevator car side walls. At least one elevator car side wall is configured to be linearly translatable at least partially across the floor from an operational position to a maintenance position to allow for inspection and/or maintenance of elevator system components from inside of the elevator car when the elevator car side wall is at the maintenance position. A method of operating an elevator system includes driving an elevator car along a hoistway, stopping the elevator car at a first selected location along the hoistway and linearly translating a side wall of the elevator car at least partially across a floor of the elevator car from an operational position to a maintenance position, defining a maintenance area between the side wall and the hoistway. Maintenance operations on elevator system components are performed from the maintenance area.

摘要： Elevator systems and methods of operation include a tension member support positioned within an elevator shaft, a tension member suspended from the tension member support within the elevator shaft, and a slack detection system. The slack detection system includes at least one biasing element housed within the tension member support and operably coupled to the tension member, the at least one biasing element arranged to receive a load from the tension member and a switch arranged to be moved from a first position to a second position in response to movement of the at least one biasing element, wherein when in the second position the switch triggers an emergency stop of an elevator car within the elevator shaft.
