Special Mounting
Box Truck/Trailer, Softside or Curtainside
Special consideration must be given to transport vehicles that have enclosures built around
the beds of truck or trailers. These types of enclosures are called ‘Box Truck/Trailers’, ‘Soft Sides’ or
‘Curtainsides’. Items such as the rear door, lock rods and rear door hardware, can cause interfer-
ence with the PIGGYBACK
®
, during the mounting process. The rear sill and possibly the frame of
the transport vehicle must be built out to allow for mast clearance.
The rear sill build-out can be accomplished using structural tubing, ASTM A500 Gr. B, welded to
existing rear sill. Strengthen surrounding structure as needed with frame extensions and gussets.
The dimensions below are intended as a guideline, which can also vary based on forklift model,
mast forward tilt and mast height.
