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： An illustrative example embodiment of an elevator sheave assembly (30) includes a plurality of polymer rings (40, 50) that are secured together. The plurality of polymer rings (40,50) includes at least two polymer rings (40, 50) that each have an outer circumferential surface (42, 52) that defines a portion of a belt guiding surface (44, 54) adjacent a flange (46, 56) at a longitudinal end of the sheave assembly (30). The at least two polymer rings (40, 50) each include a bearing (70) supported inside the ring (40, 50).

摘要： A load bearing tension member for an elevator system includes a plurality of tension elements arrayed across a tension member width. The tension elements are offset from a tension member central axis, the central axis bisecting a tension member thickness and extending across the tension member width. The tension elements include a plurality of fibers extending along a length of the tension element, and a matrix material in which the plurality of fibers are embedded. A jacket at least partially encapsulates the plurality of tension elements.

摘要： Making a passenger handrail (30) includes splicing together ends (58) of handrail stock. A disclosed device (50) includes mounting members (54), (56) for positioning the ends (58) of the handrail stock relative to each other before splicing them together. Example mounting members (54), (56) include position control members (80) having at least one tooth (82) for engaging a tooth (36) on a driven surface (34) of the handrail. A disclosed example includes a mover (62) having a threaded rod (66) that causes a follower (68) to move with the mounting member (54) for adjusting a position of the mounting member and the corresponding end (58) of the handrail stock within very stringent tolerance requirements.

摘要： The invention provides an automatic handrail tensioning system and a method for adjusting the tension degree of a handrail, and belongs to the technical field of Escalator. The automatic handrail tensioning system of the present invention comprises: a sensor for detecting information that can reflect a tension degree of the handrail; a controller for determining the tension degree information of the handrail according to the information detected by the sensor, and generating a corresponding control instruction for adjusting the tension degree of the handrail based on the tension degree information; and an actuator for driving a tensioning device to adjust the tension degree of the handrail based on the control instruction.

摘要： A load bearing member (34) for supporting an elevator car (10) has a plurality of tension members (38) that bear the weight and counterweight of the elevator car (10). The plurality of tension members extends along a length. An outer cover (42) envelopes the plurality of tension members and has a first surface and a second surface. The plurality of tension members are sandwiched between the first surface (46) and the second surf ace (48). The first surface is for traction on a sheave (22). The first surface and the second surface define a cross-section (52) transverse to the length of the load bearing member. The cross-section has a first end portion (56), a middle portion (60) and a second end portion (64). The middle portion has a first width (wl) between the first surface and the second surface which is smaller than a second width (w2) between the first surface and the second surface of one of the first end portion and the second end portion.

摘要： A method of monitoring a suspension member of an elevator system includes determining a condition of the suspension member based on a combination of an electrical inspection technique, a use indicator corresponding to an amount of use of the suspension member, and a mechanical characteristic indicator corresponding to at least one mechanical characteristic of the suspension member. The suspension member is removed from service based on an indication from the electrical inspection technique, the mechanical characteristic indicator, and the use indicator satisfying at least one predetermined combination of criteria.
