The information provided in this document herein supersedes any previous EZ Hitch™ mounting
installation information.
If the transport vehicle is a ‘Box Truck/Trailer’, ‘Soft Side’ or ‘Curtainside’, refer immediately to sec-
tions 10 and 12, to see if you have the correct kit P/N and/or need additional information.
Most EZ Hitch™ mount installs require counter weight for the transport vehicle. In order to ensure
the safe operation of the transport vehicle, unladen with a mounted PIGGYBACK
®
, a truck or trailer
analysis sheet must be filled out. Truck or trailer analysis sheets can be obtained at the end of this
document, our website at
www.piggy-back.com
or by contacting directly our Technical Support
Mounting Specialists. Failure to properly counter weight a transport vehicle may result in poor trac-
tion, braking and/or vehicle instability.
In addition, truck/trailer weighing procedures can also be found at the end of this document.
Based on the transport vehicle frame structure, additional frame reinforcement might be necessary.
Frame body reinforcement recommendations (if applicable) will be provided, at the time of a finalized
truck or trailer analysis calculation(s).
The complete EZ Hitch
™
mounting system must be installed to provide proper mounting and to
retain full PIGGYBACK
®
warranty.
While installing the EZ Hitch
™
mounting system, the truck/trailer brakes must be applied and
wheels must be chocked so that no unwanted movement occurs.
All welding must be done by certified welder(s) with qualification in accordance with AWS D1.1.
Disconnect battery cables on the PIGGYBACK
®
forklift and the truck/trailer before welding or battery
explosion may occur. It is also advisable to disconnect the ECU on PIGGYBACK
®
model forklifts
with Tier 4 final engines.
Contact your local State Highway Patrol for information concerning local load limits, width limits, and
other limitations.
The Princeton EZ Hitch Mounting System incorporates three safety features for proper trans-
port of a PIGGYBACK
®
forklift. The frame hooks, safety chains and hitch pins. All three of
these items must be in proper working order and free of damage for proper and safe trans-
port of a PIGGYBACK
®
forklift.
