I can help
I have a few questions:
1. So the two outside beams are approx. 7' apart with the 3rd beam splitting the outside beams?
2. Can you get me the exact depth, flange width and flange thickness to the nearest 1/8" so I can look up your beams in the AISC tables?
3. Do you know the axle spacing and axle loads for your truck?
Do you have a picture of the crane that you can share with me?
How about my questions #1 and #2?
