    摘要: A load bearing assembly (20) includes a plurality of tension members (22). A joint in the load bearing assembly (20) has a staggered pattern of discontinuities (30) in the tension members (22). A stress relieving feature is associated with at least outermost tension members (22A, 22L) in the vicinity of the discontinuities. One example includes supplemental tension members (32, 50) as the stress relieving feature. Another example includes selected spacings (32, 40, 42) between ends of at least some of the tension members. One example includes different sized tension members as the stress relieving feature. Another example includes different lateral spacings between selected tension members.

    摘要: A system (10) manages power from a secondary power (30) source to supply power to elevator and building systems (18) after failure of a primary power source (20). An available power monitor provides a measure or estimate (such as state-of-charge) of the power available from the secondary power source. A demand monitoring system (46) generates a signal related to passenger demand for each elevator in the elevator system. A controller (34) then prioritizes allocation of power from the secondary power source to the elevator and building systems based on the available power from the secondary power source and the passenger demand in the elevator system.

    摘要: In an elevator sheave for a flat belt, the optimum crown height is within a range of approximately 0.033 to about 0.003 times the width of the elevator rope. The optimum radius is in the range of about 16.67 to about 50.00 times the width of the elevator rope. Both the crown height (h) and the crown radius (rc) may be expressed as a function of belt width (Wb). The groove width (wg) is in the range of approximately 1.5 and 2.25 times the width of the belt (Wb). A circumferential surface roughness of about 1.0 to 3.0 is applied. A hard, thin surface coating can be applied to enhance durability while maintaining traction.

    摘要: A power system (10) operates a plurality of hoist motors (18a, 18b, 18c), each of which controls movement of one of a plurality of elevators (12a, 12b, 12c). The power system (10) includes a power bus (11) and a converter (22) connected across the power bus (11) for converting alternating current (AC) power from an AC power source (20) to direct current (DC) power and delivering the DC power to the power bus (11). The power system (10) also includes a plurality of inverters (26a, 26b, 26c) connected across the power bus (11). Each inverter (26a, 26b, 26c) is connected to a hoist motor (18a, 18b, 18c) and is operable to drive the hoist motor (18a, 18b, 18c) when the hoist motor (18a, 18b, 18c) is motoring by converting the DC power from the power bus (11) into AC power. Each inverter (26a, 26b, 26c) is further operable to convert AC power produced by the hoist motor (18a, 18b, 18c) when the motor is generating to DC power and to deliver the DC power to the power bus (11). A controller (31) manages power on the power bus (11) by controlling operation of the converter (22) and the inverters (26a, 26b, 26c) to drive a motoring hoist motor with power delivered to the power bus (11) by the converter (22) and generating hoist motors.
