Fifth Wheel Air Slide Control
Notice: Do not activate the fifth wheel slide control valve while the vehicle is in motion. To do so could cause damage to the fifth wheel member, the kingpin, the cab or trailer, and ultimately to the drivetrain.
The fifth wheel air slide valve permits repositioning of the sliding fifth wheel from inside the cab. Moving the air slide control valve switch to the lock position deactivates the control valve and locks the fifth wheel to the baseplate. See Fig.. Moving the switch to the unlock position activates the control valve and unlocks the fifth wheel slide mechanism, allowing changes to the total length of the tractor-trailer and changes to axle loads to comply with varying state or provincial laws. A red indicator light, if so equipped, is illuminated whenever the fifth wheel slide is unlocked. A guard is positioned around the switch to minimize accidental activation.
