The carriage rail must be crowned exactly above the crown centerline.
This can be accomplished with a special length insert from the factory.
Position the machine so that the crown centerline occurs at the ends
of the special insert. The paving rollers must always turn in only one
direction when paving skewed decks. The rotation of the rollers should
be set so that they finish the concrete only when the carriage travels
from the leading end of the machine to the trailing end of the machine.
The paving rollers should rotate so that the bottom of the rollers rotate
against the concrete as the carriage travels from the leading end to
the trailing end of the machine. The paving rollers are mounted on the
lower carriage turntable and can be turned to any angle for finishing
skewed decks.
To skew the paving rollers follow the steps below:
1. Manually disconnect the skew cylinder, if it is installed on the
machine, and tie it back or remove it from the carriage.
2. Loosen the skew stop clamps and rotate the paving rollers to
the desired skew angle.
3. Use the roller directional valves and position the two valve
levers in the same direction. Facing the augers, both rollers
turn clockwise when the carriage travels to the left and counter
clockwise when the carriage travels to the right. Put the auto-
matic roller reversing valve in the “Non-Reversing” position.
The “Non-Reversing” position does not change the roller direc-
tion with each pass of the carriage.
When a skewed deck is super elevated, the leading end of the
machine must be at the low side of the deck. This permits the
carriage to finish as it travels up the slope.
