I would like to build a bridge crane and would like your suggestions or thoughts.
For the runways I am thinking about using two W10x22 beams to span 24'
Columns 5" Box tubing - 10' tall - Beam bolted to top and gusseted about 2' x 2' back to columns.
The span between the beams will be about 15'
As for connecting the two beams together, I plan on using 8" channel near the ends of the beams and x-bracing the columns with 2"x2"x1/4" angle.
My thoughts are to build a bridge that rides between the W10x22's.
What are the effects of the bridge cars riding inside the beam on the flange itself?
What kind of weight can I safely lift with my chosen beams this way?
(Goal is 1 1/2 ton - heaviest lifts will be about 8' from the columns)
How much strength is lost and is there anything that can be done to minimize any twisting effects on the top beam flange?
(ie. cap with channel or tie them together on top?)
Would I be better off lowering the whole system and making a bridge that runs on top of the beams?
