Abstract: An elevator brake wedge is provided and includes an elongate body having first and second generally opposed major surfaces and first and second generally opposed minor surfaces. The second minor surface has a greater length than the first minor surface. Each of the first and second major surfaces extends between corresponding first and second ends of the first and second minor surfaces, respectively. The second major surface defines low-friction film securing grooves extending from a plane of the second major surface into the elongate body.

Abstract: A belted elevator system (10) includes a hoistway (14) and an elevator car (12) suspended in the hoistway (14) via a suspension member (16) and drivable along the hoistway (14). The suspension member (16) is routed over a plurality of sheaves (18). A sheave (18) of the plurality of sheaves includes a shaft (36) defining a central axis of the sheave (18), the sheave (18) rotatable about the central axis. A sheave outer member (38) is operably connected to the shaft (36) and rotatable about the central axis. The sheave outer member (38) includes a sheave outer surface (44) interactive with the suspension member (16). The sheave outer member (38) is formed from a molded plastic material.

Abstract: A position reference system of an elevator system includes a reference element having a fixed position in a hoistway of the elevator system, and an optical sensor configured to move along the hoistway with an elevator car of the elevator system and configured to transmit a signal to the reference element to determine the position of the elevator car. An airflow duct is configured to move along the hoistway with the elevator car. The airflow duct is configured to passively direct an airflow toward the reference element to prevent accumulation of particles on the reference element.

Abstract: A system for dynamic assignment of buttons on destination entry terminals (DETs) is provided. The system performs operations that include identifying a message for display on a touchscreen display of a destination entry system of an elevator. The message includes a selection button for display on the touchscreen display. The at least one selection button is displayed at a first location on the touchscreen display. The at least one selection button is displayed at a different location on the touchscreen display once a rearrangement criterion is satisfied.
