    摘要： A passenger conveyor handrail (30) is driven by a device (40) including a toothed drive belt (42). An example drive belt has a plurality of teeth (46) with an at least partially concave surface (50) for engaging teeth (36) on the handrail (30). A disclosed example also includes at least partially convex projections (52) near an end of each tooth on the drive belt (42). A driven surface (48) of the drive belt (42) includes a plurality of grooves (70) arranged to allow the drive belt to slip relative to a drive wheel (60) under certain loading conditions. The disclosed example arrangement facilitates proper engagement between a drive belt (42) and a toothed handrail (30) while avoiding vertical separation forces between them, which allows for eliminating pinching rollers that would otherwise engage a gripping surface (32) on the handrail (30).

    摘要： An elevator counterweight (24, 34) includes a buffer member (40) supported for movement with the counterweight within a hoistway (26). The buffer member (40) includes a first portion (52) that is within an outer boundary of a structure (42) of the counterweight. A second portion (54) of the buffer member (40) is beyond the outer boundary. In disclosed examples, a plurality of fillers are supported by a frame such that a first filler (60) has a first width dimension and at least one second filler (62) has a smaller width dimension. The second filler (62) can be positioned alongside the first portion (52) of the buffer member (40).

    摘要翻译： 升降机配重（24,34）包括缓冲构件（40），所述缓冲构件（40）支撑成与所述配重在井道（26）内运动。 缓冲构件（40）包括在配重的结构（42）的外边界内的第一部分（52）。 缓冲构件（40）的第二部分（54）超出外边界。 在公开的实施例中，多个填料由框架支撑，使得第一填料（60）具有第一宽度尺寸，并且至少一个第二填料（62）具有较小的宽度尺寸。 第二填料（62）可以位于缓冲构件（40）的第一部分（52）的旁边。
