People mover tram systems at major metropolitan airports are designed to quickly transport passengers between concourses. The people mover trams play a critical role in large airport operations, and in some cases can operate up to 7 days a week, 365 days a year. The challenge for the customer was finding a U.S.-based single-source supplier for the actuators required to maintain tram operations in both a timely and cost effective manner.



The existing actuators provided three different functions consisting of a cable lift, a station brake, and a movable sheave application. After carefully studying the actuators in use, Duff-Norton was able to match the dimensions, speed and force required for a drop-in fit. There are currently a total of 18 Duff-Norton SuperCylinders installed for this application: seven station brakes, three moveable sheaves, and eight cable lifts keeping the tram in constant operation.
