A belt and a method for manufacturing a belt is provided. The belt includes a plurality of lengthwise-extending tension members and a jacket. The jacket substantially retains the plurality of tension members. The jacket has a first side region, a second side region, and a center region between the first and second side regions. The first and second side regions of the jacket are more fire retardant than the center region of the jacket.

Fire-retardant belt

An assembly comprising (a) a belt, which includes a plurality of wire cords extending lengthwise of the belt with spaces therebetween, and includes a coating of the cords extending into the spaces between the cords, said belt being configured for use in an elevator system as a suspension belt for a car and a counterweight, or being configured for use in an elevator system as a drive belt for a car or for a counterweight, or being configured for use in an elevator system as a combined suspension and drive belt for a car and a counterweight; (b) a first connecting device including a first number of cord contacting elements providing electrical connections contacting element-to-cord; and (c) a second connecting device, including a second number of cord contacting elements providing electrical connections contacting element-to-cord, and including at least two conductive elements, each being electrically connected to a respective one of the cord contacting elements, the conductive elements being provided for making electrical connections to a belt monitoring unit which monitors the proper condition of the cords on the basis of electrical signals passed through the cords; (d) wherein at least one of the first and second connecting devices includes at least one bridge type cord contacting element, which extends into the gap between two cords and provides electrical connection to both cords, thereby electrically connecting the two cords.

A steering angle of an elevator sheave on a shaft is adjusted at installation and subsequently during maintenance by one of several embodiments. In one embodiment, a bolt with a jam nut is adjusted to position the shaft precisely. In another embodiment, a tee bracket is anchored to a hoistway wall, and a jack bolt with shims is used to adjust the vertical placement of the long beams that support the elevator car frame and therefore the shaft.

Method and apparatus for adjusting steering angle for elevator sheave

A termination for an elevator tension member is provided that terminates a load with frictional forces created by wrapping the tension member about a body and with compressional forces generated by the weight of the load compressing the tension member upon itself.
