Abstract
A system for adjusting tandems in tandem axle trailers from within a cabin of the trailer and without requiring an operator of the tandem axle trailers to leave the cabin to adjust the tandems. The system includes a tandem air valve installed within a cabin which on actuation operates a pneumatic unit for adjusting the tandems. The pneumatic unit can engage and disengage a kingpin for sliding the tandems.
