Having a truss yard for 34 years I have seen many people use trusses to hoist loads. If you copy the truss and take the drawing to a truss yard they can run in computor and tell you how much trusses can hold. They can put point loads on bottom cord and tell how the truss stresses. Take lenght of bottom cord, height at center from bottom of bottom cord to top of top cord. Draw size of gang nails on your picture so they can tell if gang nails are big enought. We oversize plates and underspan truss designs so ours are ok most of time, most truss yards do same.
