Sliding the Tandem (cont.)
5. Once the tandems have been repositioned and
the tractor’s parking brakes are set, the driver
must visually inspect and verify all locking pins
are fully engaged in the slide rails and the handle
is in the locked position. The trailer can then be
operated.
6. Only when there is minimal traction from rain,
snow, or gravel it may be necessary to apply
the trailer parking brakes while traveling at a
minimal speed. This practice aids in breaking the
friction between the tandem and slide rails and is
acceptable as long as the driver slows to a creep
just before contacting either the forward or rear
stop bar.
An example of a trailer sliding tandem warning label
can be found on Page 34.
