Abstract:
In an elevator hoisting machine, a rotating shaft is rotatably supported in a bearing mount. The rotating shaft is rotated by a driving force from a drive motor. An elevator car is raised and lowered by means of a main rope by rotation of the rotating shaft. A main rope winding portion around which the main rope is wound is formed integrally on the rotating shaft. A rope groove into which the main rope is inserted is disposed on the main rope winding portion.
Abstract:
A rope structure (20) comprising a plurality of rope subcomponents (50), a plurality of bundles (40) combined to form the rope subcomponents (50), a plurality of first yarns (30) and a plurality of second yarns (32) combined to form the bundles (40). In one embodiment, the first yarns (30) have a tenacity of approximately 25-45 gpd and the second yarns (32) have a tenacity of approximately 6-22 gpd. In another embodiment, the first yarns (30) have a breaking elongation of approximately 2%-5% and the second yarns (32) have a breaking elongation of approximately 2%-12%.

Abstract:
A thin buffer layer (303) is used to coat on the multi-filament (401) wrapped string to fill the gaps. The polymers of the buffer-layer coating have a high melt-flow (low viscosity) during coating process to fill all the gaps between the filaments, and the filaments are fixed by the coatings onto base core materials.
Abstract:
A load bearing member (22) useful in an elevator system (10) includes at least one elongated tension member (36), a conversion coating (46) on the elongated tension member (36), and a polymer jacket (34) at least partially surrounding the coated elongated tension member (36). In one example, the conversion coating (46) includes at least one of an oxide, a phosphate, or a chromate.
Abstract:
In an elevator, preferably one without machine room, a hoisting machine engages a set of hoisting ropes via a traction sheave, said set of hoisting ropes comprising hoisting ropes of substantially circular cross-section. The ropes have a load-bearing part twisted from steel wires of circular and/or non-circular cross-section. The steel wires of the hoisting ropes have a cross-sectional area larger than about 0.015 mm and smaller than about 0.2 mm and a strength exceeding about 2000 N/mm . The elevator preferably has a hoisting machine of substantially light weight relative to the nominal load.

Abstract:
In an elevator, preferably one without machine room, a hoisting machine engages a set of hoisting ropes via a traction sheave, said set of hoisting ropes having a load-bearing part twisted from steel wires of circular and/or non-circular cross-section, and in which elevator the hoisting ropes support a counterweight and an elevator car moving on their tracks. The weight of the hoisting machine of the elevator is at most about 1/5 of the weight of the nominal load of the elevator.
