Ice mitigation for bridge cables is provided by a system having a plurality of heaters on one or more bridge cables, extending parallel to a longitudinal axis thereof, arranged in a plurality of heater sections, and configured to heat an outer surface of the bridge cables, and a control system including one or more controllers configured to individually activate and regulate heating output of the heater sections to prevent snow or ice from falling from the bridge cables. The heater sections can be arranged radially, about a circumference of the bridge cables, and/or axially, end to end along a length of the bridge cables, so that power can be individually directed to the heater sections to account for differing heating requirements at different radial and/or axial aspects of the bridge cables.

A preassembled parallel wire cable creates a random cast of loops. Any of the random cast of loops is hung for transport, thus eliminating costly and time-consuming coiling and reeling operations.

A parallel wire cable is produced from a plurality of wires arranged in a bundle for use as a structural cable. Each wire in the plurality of wires is parallel to every other wire in the bundle, and each wire in the plurality of wires is tensioned to a tension value.

An electrified-cable system is disclosed herein. The system includes first and second wires each having a longitudinally-extending uninsulated region comprising at least a portion of the circumference of the first wire, and a longitudinally-extending insulated region comprising the remaining circumference of the first wire, and an insulating connector that couples the insulated region of the first wire to the insulated region of the second wire. The system is configured to form an electrical circuit from the first wire to the second wire through a carriage in electrical contact with the uninsulated region of the first wire and the uninsulated region of the second wire. A corresponding method is also disclosed.

A belt for an elevator system and a method for making the same is provided. The belt includes a plurality of tension members that extend along a length of the belt and a jacket. The jacket substantially retains the plurality of tension members. The jacket maintains a desired spacing and alignment of the tension members relative to each other. The jacket includes a plurality of first fibers and a plurality of second fibers. The jacket defines at least one exterior, traction surface of the belt. The first fibers are at least partially disposed between the tension members and the traction surface of the belt. The second fibers are fill fibers. The first fibers have at least one property that distinguishes them from the second fibers.

A device 100 produces an endless winding cable 101 by winding a yarn 106 around two thimbles 102, 104. The device 100 comprises an elongated guide 110, a carriage 112, a yarn feeder 114, a first thimble holder 116, and a second thimble holder 118. The first thimble holder 116 and the second thimble holder 118 each hold one of the two thimbles 102, 104. The carriage 112 is movable relative to the elongated guide 110. The yarn feeder 114 is connected to the carriage 112, and comprises at least one spool holder 120 for holding a spool 122 with the at least one yarn 106, and an output guide 124 for guiding the at least one yarn 106 to the cable during winding. The yarn feeder 114 comprises at least one yarn brake 126 for controlling a tension of the at least one yarn 106 during winding.
