Abstract:
A belt for suspending and/or driving an elevator car includes a plurality of wires arranged into a plurality of cords. The plurality of cords includes one or more inner cords located at an innermost portion of the belt relative to a lateral end of the belt and one or more outer cords located laterally outboard of the one or more inner cords. The one or more outer cords have a construction distinct from the one or more inner cords. A jacket substantially retains the plurality of cords.
Abstract:
An exemplary method of making a first component for contacting another component includes applying a wear and corrosion resistant material layer onto a surface of the first component. The wear and corrosion resistant material layer is then roughened subsequent to having been applied to the surface. A component comprises an exemplary elevator sheave that includes a metallic body having a sheave surface that is adapted to contact an elevator tension member. A corrosion resistant material layer on the sheave surface has a thickness that is greater than about 5 microns.
Abstract:
A belt for suspending and/or driving an elevator car includes a plurality of wires arranged into one or more cords and a jacket substantially retaining the one or more cords. Each cord includes a plurality of wires arranged around at least one non load-bearing core. An elevator system includes an elevator car and one or more sheaves. One or more belts are operably connected to the car and interactive with the one or more sheaves for suspending and/or driving the elevator car. Each belt of the one or more belts includes a plurality of wires arranged into one or more cords and a jacket substantially retaining the one or more cords. Each cord includes a plurality of wires arranged around at least one non load-bearing core.
Abstract:
A belt for suspending and/or driving an elevator car includes a plurality of wires arranged into a plurality of strands. The plurality of strands includes one or more center elements with a plurality of outer wires arranged around the one or more center elements and includes one or more anchorage features to limit relative movement of the plurality of wires. A jacket substantially retains the plurality of strands.
Abstract:
An elevator safety apparatus includes a deformable member (18) configured to buffer a mass (14, 26) in a hoistway (12) of an elevator system (10) and one or more sensors (20) configured to sense degradation of the deformable member (18).
