The engineering tables state that the size I-beam (and span) will support 4000#, although my chain hoist is only rated for 2200#.
Horizontal 'foot' beams & vertical beam are 4x4x .250"
Angle braces are 3x3x .125"
Gusset plates are 12x12x .250"
I-beam is 5"x5" (25#/foot)
Casters are 8", all four locking, 800# capacity per caster.
Probably have $250 to $300 in mine (the casters cost about $120 of that
)
Just make sure the width between the uprights is as wide as your trailer or truck plus 12" more on each side.
For height, if you select your trolley & hoist first, you'll know how much headroom they need. Mine are Ross brand from http://hoistsdirect.com/ .
Good luck & post some photos!
