Elevator Access Control
Elevator traveling cables and the accompanying labor are expensive. Eliminate costly installation of traveling cables in elevator shafts. WILDR works in tandem with any access control system to provide up to 3,000 ft. of elevator access control to eliminate the problems and costs of traveling cable. Elevator shafts are harsh electrical environments and often the source of noise that interferes with card reader data and control lines. The SciTech Wildr system can actually cut the cost for installation of traveling cable to less than half of a conventional retrofit.
What is a traveling cable?
Elevator traveling cable is a link between the elevator car and controller. In conventional elevators, all power and signal information is transmitted through the traveling cable. The vast majority, as much as 95%, of wire and cable required will be installed in a fixed location. The remainder will be used where some motion is required. Flexible cables – in motion during service, such as mining cables, oil well boring cables, crane cables and elevator traveling cables – are expected to last for a while. Elevator traveling cable is a specialized multi-conductor cable continually in motion and must last for many years thus very expensive.
Installation of a typical traveling cable
Traveling cable is typically mounted in the elevator hoistway, where each end is terminated, and alternately takes the full load of the suspended cable as the car moves up and down. The hoistway termination may be in a midhoistway junction point or in the machine room.
When terminating the cable in the machine room, the need to make electrical connections in the junction box is eliminated, but the resulting longer traveling cable may be more susceptible to trailing problems from building sway or wind. One intermediate installation technique terminates the traveling cable at the hoistway midpoint – using the steel support member – and continues to run the traveling cable to the machine room. This eliminates labor required for mid-hoistway electrical terminations and restricts the free-hanging cable length. This method can be used for both round and flat type traveling cables.
