Low-boy trailer vertical curve design
Low-boy trailer vertical curve design
(OP)
We need to design an access ramp into a site with a 15.5' vertical drop to accomodate a 63' long lowboy trailer. We need some dimensions of tractor/trailer combinations depicting ground clearance, vertical transition and turning radii.

It will make a difference whether you are talking about a true lowboy trailer (used for heavy equipment hauling) or a drop center trailer (also used for equipment hauling, but can be used for container transport). A drop center trailer actually separates into two pieces and is driven onto from the front; whereas, a lowboy is accessed by rear drive on ramps.
A 63-foot trailer is a long trailer. Probably requires a special permit.

Did you try contacting the manufacturer for a simple CAD profile of the trailer? I am sure most companies are pretty willing to do that.
I know we were designing a steeper than normal access road for golf carts and a particular manufacturer was very willing to help.
