Giant truck dumping ramp - photo

Jon, The trailer looks like maybe an open top 40' container, possibly even on a skel chassis. No lifting capability. The sawdust/grain fires are because of static electricity caused from rapid movement of particles or high friction, not something that would happen (probably) in an open air dumping....and the volume difference per truck movement would be in the order of 6x based on 14 cu yd truck...just my 2 cents, cheers
