An elevator system comprising a shaft having a pit, a car guided by a pair of first guide rails to be vertically movable in the shaft, a counterweight connected to the car by a suspension rope, the counterweight being guided by a pair of second guide rails to be vertically movable in the shaft, and a counterweight screen in a space between the counterweight and the car, the counterweight screen being attached to the second guide rails at the pit. The counterweight screen is a sandwich-structured composite panel.

A guide rail bracket assembly, for connecting a car guide rail to a pair of left and right counterweight guide rails in an elevator system, includes a guide rail bracket for horizontally connecting the car guide rail to the pair of left and right counterweight guide rails. The guide rail bracket comprises a first end portion for attachment to the left counterweight guide rail, a second end portion for attachment to the right counterweight guide rail, and an intermediate portion for attachment to the car guide rail. The guide rail bracket assembly further comprises a first interface bracket for attaching the first end portion to the left counterweight guide rail, a second interface bracket for attaching the second end portion to the right counterweight guide rail, and a third interface bracket for attaching the intermediate portion to the car guide rail.

A stabilizing system may be utilized to reduce or eliminate sway of magnetic tape that is suspended in an elevator hoistway and provides a positional reference to an elevator cab. The stabilizing system may include a stabilizing mechanism fixed within a hoistway and a roller cam disposed on the elevator cab. The stabilizing system may include a telescoping member attached to a guide having opposing flanges that restrict movement of the tape. The telescoping member and the guide may be biased in an extended position, where the guide partially surrounds the tape. In a retracted position, the guide is horizontally spaced apart from the tape. When the elevator cab passes the stabilizing mechanism, the roller cam may force the guide and the telescoping member into the retracted position to prevent any contact between the stabilizing mechanism and components disposed on the elevator cab.

A building includes a prefabricated modular stair or elevator module. The prefabricated stair or elevator module may form either a fully functional stairwell with an internally supported internal landing and handrails, or a fully functional elevator shaft ready to install an elevator system through a plurality of engagement features. Each prefabricated stair/elevator module includes four vertical members extending orthogonally from a reference plane, four transverse members forming transverse edges of the module, and four longitudinal members forming longitudinal edges of the module. The prefabricated modules may be stacked upon one another and fixedly attached to one another through fastening members and fasteners. Furthermore, each module may be covered in wall panels such that each module forms a segment of either an elevator shaft or a stairwell.

An elevator system arranged in an elevator shaft of a building in the construction phase grows with the building using a lifting process. The system includes a machine platform with an elevator drive machine and an elevator car suspended on the machine platform by a carrier. The elevator car is raised during the lifting process by a lifting device. The elevator system also includes an assembly platform that can be mechanically moved in relation to the machine platform along the elevator shaft. The lifting device includes a drive arranged on the machine platform and is also used to move the assembly platform.

A mounting device for performing an assembly process in an elevator shaft of an elevator system includes a support component and a mechatronic assembly component. The support component moves within the elevator shaft. The assembly component is retained on the support component and carries out a mounting step in an at least partially automatic manner during the assembly process. The support component includes a fastening part that secures the support component and/or the assembly component in a direction extending transversely to the vertical, i.e. for example in a horizontal or lateral direction, within the elevator shaft.

A mounting device for performing an assembly job in an elevator shaft of an elevator system has a support component and a mechatronic assembly component. The support component is configured to be moved within the elevator shaft. The assembly component is held at the support component and configured to perform a mounting step as part of the assembly job in at least a partially automatic manner. The assembly component can be an industrial robot. The mounting device allows repetitive mounting jobs, such as drilling holes and driving in screws, etc., to be performed in a partially or fully automated manner. The mounting effort, time, and/or costs thereby can be reduced.

The invention relates to a construction time elevator arrangement comprising a hoistway; a protection deck mounted within the hoistway for protecting the portion of the hoistway below it from falling objects; the protection deck comprising a roof member extending diagonally across the hoistway and covering the hoistway such that it blocks objects and/or water from falling into the hoistway below it; and a cross member extending in horizontal direction across the hoistway below the roof member. The cross member is pivotally connected with the roof member, the protection deck being collapsible into a transport state by pivoting the cross member and the roof member towards each other. The invention relates to a method implementing the construction time elevator arrangement.

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.
