摘要： A unitized segmented sheave assembly is provided. The unitized segmented sleeve assembly includes sheaves arrayed in a side-to-side formation and respectively comprising bearings and an exterior running surface and spacers interleaved between neighboring sheaves. Respective inner races of the bearings of each sheave and respective interior portions of each spacer cooperatively form an interior annular surface. The unitized segmented sheave assembly further includes a sleeve disposable in abutment with the interior annular surface.

摘要： 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.

摘要： The invention relates to an elevator comprising an elevator control having a motor drive of an elevator motor driving an elevator car on an movement path, which motor drive comprising a frequency converter with a rectifier bridge designed to be connected to mains, a converter bridge for feeding the elevator motor and an intermediate DC circuit located in-between, the elevator further comprising a brake drive for supplying energy to at least two motor brakes with the brake drive being connected to the intermediate DC circuit as well as an emergency power supply battery designed to allow safe release of passengers in case of a power outage. According to the invention the battery is connected to the intermediate DC circuit, and the elevator control has a measuring circuit connected to the intermediate DC circuit and the elevator control has a battery testing module which is configured to apply a defined load to the battery and to measure the voltage of the DC circuit for a defined time period. The battery testing module comprises a comparator for comparing the measured voltage with at least one stored first threshold value, whereby the elevator control is configured to issue a replacement signal for the battery dependent on the signal of the comparator.
