2. Secure Carriage on Rail
A. Select the correct pair of holes on each side of the carriage for the rail diameter being used (see
chart at right). If the wheels are not attached to the correct set of holes, remove the wheel brackets
and bolt them in selected holes. Tighten the bolts until the brackets are snug but still free to rotate.
B. Open the cam handle to separate the two halves of the split carriage. Loosen and turn the clutch
knob counterclockwise to put the drive in the declutched position.
C. Place the carriage on the ring rail with the wheels in the rail grooves. Close the cam handle and
move the carriage back and forth a few inches. The wheels on their mounting brackets will align
themselves correctly with the rail grooves.
D. Verify that wheels are properly aligned,
then tighten the wheel mounting bolts to
lock them in position. Rotate the clutch
knob clockwise to engage the drive pinion
with the rack.
E. Verify that pinion is properly engaged
in rack. The correct wheel position will
provide a minimum of 50% engagement
between the drive pinion and the gear
rack.
1. Install Rail
The Piper-Plus is designed for use with Bent Rigid Rail (BRR) or Ring Rail. The exact outside diameter
(OD) of the work piece, including coating, must be known when ordering rail. Minimum pipe OD is
16 inches (406 mm). Rail is custom bent for each OD and features adjustable feet to accommodate
pipe ovality and deviations in coating thickness.
CARRIAGE WHEEL ADJUSTMENT
The wheels along one side of the carriage have stainless
steel shim washers (A) underneath. These wheels are
adjustable. Readjust these wheels (if necessary) by
rotating the hex bolt (B) with a 1/2" wrench.
Grasp the sides of the carriage. The wheels are too loose
if it is possible to move the carriage from side to side or
up and down. Use a finger to keep one of the adjustable
wheels from rotating as the carriage is manually pushed
along the track. The wheels are adjusted too tight if firm
finger pressure is not enough to prevent wheel rotation.
Repeat the process for the other adjustable wheel.
