Hi people,

I need to be able to lift stuff on and off a flatbed car hauling
trailer.

I want to build a gantry with an I-beam across the top with a wheeled
trolly for a chain hoist. I need a 3 ton dead lift, the clearance
under the beam is about 10 feet, and the width it can straddle will
also be about 10 feet.

I do NOT need it to have casters for moving but it does need to be
free-standing so I can push it around the shop with the fork lift when
NOT loaded.

Anyone have some plans or can point me in the direction of where I
might get info on the desing and building one?

Basically, the sizes of the support columns (pipe or UC) and the main
beam would be all I really need. I can wing it from there.

Here's one but I don't need it to telescope but I do need 3 ton lift.
