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 elevator system includes a hoistway defined in a surrounding structure, and an elevator car and at least one counterweight disposed in the hoistway. The hoistway defines an overhead space over a vertical extent of the hoistway between a ceiling of the hoistway and a top portion of the elevator car at its highest operable location along the hoistway. At least one drive motor is disposed in the overhead space and drivingly couples and suspends the elevator car via at least one flat rope or belt.
Abstract:
A deflector sheave mounting bracket 100 for mounting a plurality of individual deflector sheaves 80 of an elevator system includes a top plate 104, a bottom plate 106, and a plurality of support plates 102 connected at a first end to the top plate and connected at a second, opposite end to the bottom plate. A plurality of openings 120 for receiving the plurality of deflector sheaves is defined between pairs of adjacent support plates of the plurality of support plates. At least one opening of the plurality of openings is vertically offset and horizontally offset from another of the plurality of openings.
Abstract:
A hoist tool for lifting a machine assembly (19) in an elevator to an installation position is mounted to a machine beam (32) which also supports the machine assembly. The hoist tool (36) 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 support member configured for use in a machine room of an elevator system is provided including a base having a car end and a counterweight end. The counterweight end is arranged substantially parallel to a wall of the machine room, and the counterweight end is arranged at an angle relative to the car end. An idler sheave having a plurality of grooves is mounted to the base in an orientation generally parallel to the car end. The idler sheave is configured to rotate about a first axis of rotation. A plurality of individual sheaves is mounted to the based in a staggered configuration substantially complementary to the angle of the counterweight end relative to the car end. Each individual sheave is configured to rotate about a second axis of rotation parallel to the first axis of rotation.

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.
