Abstract: Disclosed is a ropeless elevator system having a car mover operationally connected to an elevator car, the car mover configured to operate autonomously and move along a hoistway lane, thereby moving the elevator car along the hoistway lane, wherein the car mover is connected to a top or bottom of the elevator car, via a coupling device.

Abstract: An elevator load bearing assembly includes a plurality of cords within a jacket. The jacket has a plurality of grooves spaced along the length of the belt assembly. In one example, the grooves are separated by varying spacings along the length of the belt. In another example, at least a portion of each groove is aligned at an oblique angle relative to the longitudinal axis of the belt. Another example includes a combination of the different spacings and the non-perpendicular alignment.

Abstract: A rooftop unit for a machine-roomless elevator (28) includes a selectively removable cover (38) that covers the machine components (46). In one example, the removable cover is movable relative to the rooftop without requiring removal of the entire cover.

Abstract: A single support device (30) is adapted to support and secure a machine (34) at least one sheave (38) and a plurality of termination members (44, 46). The single support device (30) is conveniently installed within a hoistway (26) or within a machine room (90). The machine (34) and sheave (38) may be premounted to the support device (30) and the entire assembly can be lowered into position by crane (300).

Abstract: An improved method for mounting elevator rails within a hoistway includes the initial step of securing support brackets to a pair of rails. The brackets, rails, a machine for driving a cab and a dead end hitch are then mounted within the hoistway. A cab may then be moved vertically within the hoistway and additional support brackets are placed at vertically spaced locations. The connection of the brackets and rails provides support to dissipate the loads which are transferred into the rail in such systems wherein the machine or the dead end hitch is fixed to a rail. Once the rails have been adequately supported by additional brackets, the brackets which are secured to the rails are removed from the rail. The brackets provide support, but are no longer fixed to the rails.

Abstract: An elevator load bearing assembly includes a plurality of cords within a jacket. The jacket has a plurality of grooves spaced along the length of the belt assembly. In one example, the grooves are separated by varying spacings along the length of the belt. In another example, at least a portion of each groove is aligned at a non-right angle relative to the longitudinal axis of the belt. Another example includes a combination of the different spacings and the non-perpendicular alignment. The inventive belt assembly minimizes the possibility for generating an annoying, audible sound and vibration during elevator operation.

Abstract: A hoist tool for lifting a machine assembly in an elevator to an installation position is mounted to a machine beam which also supports the machine assembly. The hoist tool is thus mounted in a location where it does not require any additional axial space. Preferably, the hoist tool is mounted to one lateral side of the machine assembly, and within an axial extension of the machine assembly downwardly from the machine beam into the hoistway.

Abstract: A machineroomless elevator system (10) has a controller (32)and a governor (38) positioned in the hoistway (12) at the top floor level (28), such that the controller (32) and the governor (38) are both positioned between the front wall (14) of the hoistway (12) and an elevator car guide rail (34) positioned on a sidewall (18) of the hoistway (12).
