You know, after all the comments here, etc, I think that ramps and
winches are probaly a safer way to go.

Iggy, I think the concept is safer, just not their execution. I'd rather
hand-truck a heavy item onto a ground-level platform than up a ramp.

Certainly, a trailer could be built that didn't have an 80:1 advantage
over the cylinders, and had a more positive means of locking the
assembly.

(It also appears that the trailer has no decent suspension, although it
might have those chewing gum torsion springs in the axle mounts).
