Hi, Gonna start on a pole barn in a few weeks so Im going to build a 20 foot gin pole A-frame hoist for the back of my 85 chevy ex-military K30 4x4. I will need to lift 600 pound poles. I would like to be able to lift 900 or 1000lbs. Im thinking round 4 inch dia .120 wall thickness, And then weld a 3/16 thick by 2.5in strap lengthwise along the top of each of the 20 foot tubes to add more resistance to bowing. Will have some cross bars between the poles too.
Will use a 12V winch mounted in the truck bed , cable and pulley over the top, Gin pole hung from the truck with chains. Truck will handle it fine, it is a diesel 5/4 ton former airforce truck, 14 bolt full floater rear and dana 60 front and its a heavy Biotch!!
What do you guys think about the gin pole size? Trying to get the needed strength without the Pole A frame weighing a thousand pounds. Will also use this rig for installing the roof trusses.
Thanks, Dave
