This is an early video (before final paint) of the pneumatic "super dolly" I designed and built. One small tank of Nitrogen will run the dolly for most of a soaring season with two "lifts" each day. It has two linear bearings to keep the frame parallel and four pneumatic cylinders to do the lifting. One of the castors is lockable so I can "steer" if needed. The "cradle" is separate from the frame so I could change the contour if I ever switched gliders.

I have a customer looking for hangar dolly for heavy

glider (Antares). Anything that works for Duo, Arcs,

DG-500/1000, or similar will probably work. Anybody

know of commercial fabricators of such things, or

a used one available ?

Thanks,
