NOTE: 

 Manufacturers of frameless trailers may want to consider extending their axle 

rails far enough forward that a frameless drive unit can be installed (extend 2.87m for 
255mm stroke, 2.77m for 150mm stroke). 
 
Chapter 4 discusses the drive unit installation process in more detail. 
 

2.2 Trailer alignment 

 

 
1.  Adjust the trailer to meet these conditions: 
 

A)  The trailer must be 

straight 

to allow for proper parallel movement of the 

slats/planks.  Determine straightness by sighting down a floor slat/plank 
positioned in the trailer.    

 

B)  The cross-members on which the sub-deck mounts must be level, because 

the friction based principle of the 

WALKING FLOOR

 system requires a flat
