12. CARRIAGE TRAVEL
- The carriage travel distance can be
adjusted to suit the job requirements by strategically positioning
the reversing lugs on the upper and lower travel chain. Move
the carriage to the desired travel distance at the idler end of
the machine and stop the carriage. Use your hand and push the
top striker arm of the controller until the reversing valve shifts.
Holding back the striker arm, attach the reversing lug next to the
striker arm on the top of the travel chain. Move the carriage to the
desired travel distance at the drive end of the machine and stop
the carriage. Use your hand and push the bottom striker arm of the
controller until the reversing valve shifts. Holding back the striker
arm attach the reversing lug next to the striker arm on the bottom
of the travel chain.
After the reversing lugs have been installed, move the carriage to
one of the points of direction reversal and stop the carriage. To
set the paving roller pivot device, slide a reversing paddle onto the
carriage rail. When it makes contact with the paving roller revers-
ing valve shift rod, push the paddle approximately 1-1/2 inches or
until the rod spring shifts the reversing valve. Lock the reversing
paddle in place by tightening the set screw. Move the carriage to
the opposite direction reversal point and repeat the procedure on
the other side of the carriage. Adjust the hold down rollers on the
hanger frame by loosening the holder yoke set screws. Loosen the
set screws so that the rollers exert slight pressure on the carriage
rail but still allow you to turn them by hand.
13. CROWN ADJUSTMENT
- When adjusting the crown, the
frame should be assembled and positioned so that a hinge joint
is directly above the crown center. The paving carriage should
be moved to the crown point to allow for the natural deflection
of the truss frame. Measure up from a grade point to the top of
the carriage rail on both sides of the machine (Note the measure-
ment). Adjust the bolts until the machine frame slope matches
