Why is a rack and pinion elevator system superior in ice buildup conditions?
Cable systems use pulleys with grooves for the cable located at tower top. These pulleys are not visible from ground level or from the car as it travels. It is very common for the tower top to be “iced” up with no indication at ground level. If the elevator is used in these conditions, the pulley grooves and cable guides can fill and pack with ice as the icy cables travel over them. In some cases this can cause the cable to “jump” off a pulley causing damage and shut-down of the system. Icy conditions can also cause damage to the elevator drive wheel, when increased resistance in cable path will cause the cable to slip in the drive groove, which wears the traction surface; seriously shorting the life of the drive wheel. Our Trac-Cab Rack and Pinion elevators use heavy gears that grind the ice out of the gear track. In addition, the system has been engineered for icy conditions and any other obstruction to the travel path. If for any reason the drive travel is impeded, the system will d
