Several years ago I worked with BT-Prime Mover (before the buyout by Toyota) to get a special modification to the pallet clamp for the OE35 so that a standard center stringer or a 4" square center block (typicall of Euro pallet desgins) could be clamped. Basically, a set of arms that would secure the 4" center block were attached to the standard clamp arms via a pivot pin that would allow the arms to pivot out of the way when handling standaard GMA type pallets. If I recall correctly the design could be retrofitted to units in the field.

I feel confidenat that Crown would have something similar.
