Fork Supports

EZ HITCH™
Material Required
Transverse Tube Install
NOTE:
The bottom of (front transverse tube) must be in the same
plane or lower than the top of (rear transverse tube). IF the
bottom of B is higher than the top of A, the PIGGY BACK
will not have enough tilt to angle the front tires away from the
tire pads when mounting and the PIGGYBACK's mounting
hooks will NOT reach the mounting pins.
IF the PIGGYBACK's hooks will not reach the mounting pins,
check the Tire Pad's location.
Only one method of fork supports is approved with the EZ Hitch™
mounting system. The transverse mount uses two 2" x 4"
rectangular tubes parallel to the truck axle. This method can be
used on PIGGYBACK
Quantity
2 Steel Rectangular Tubing
2" x 4" x 1/4" wall x 48" long
ASTM A-500, Gr. B
The 48" long tubing can be cut down to fit between the truck/trailer
main rails, however, it must be long enough to support all of the
forks. If the forks on the Princeton PIGGYBACK
longer, space the tubes at a 30" centerline (Figure 2) with the
bottom of the front tube level with the top of the rear tube. The
distance between the bottom of the rear truck or trailer sill and the
top of the rear transverse tube should be 3" min (Fork pocket
opening). Make sure both tubes are square and parallel with one
another and the frame body. Using 3/8" fillet welds, weld all around
the tubing to the frame rails.
