You maybe correct about it being easier to build new portable ramps and I'm considering that. My intentions are not for highway towing but local rural roads, between near by farms.
I do know that the Tall Mast Hyster's are still towed because they are too tall on low-boy equipment trailer. The come equipt. with surge brakes on the tow bar and are pulled behind a heavy truck.

I can load here at my shop since I have loading dock however would have to do some concrete work due to the weight.

Driving would be too slow since these manual tranny models can only make 8-9 mph.

BTW. The farmers like to rent my Yale three section mast 6000# when putting those large round bales of hay in the barn or in their outside stacks. Normal farm equipment can't reach that high. Almost 20ft with the right attachment.
