When I see spools on a truck, they are over the back axles. About 3 chains through the loop, blocked front and back and another couple over the top.
And we've seen other broken flat beds here at HMT.net, those loads were between rears and the pin too. I can't see a reliable loader at a plant doing this; even if the trucker is clueless. Be interesting to know if this is owner/ operator or a company tractor.
Trailers vs heavy GVW flatbed, hmmmmm.
I probably won't haul coil, more likely bar stock and structurals and occasional machinery; this has talked me out of heavy trailers. Mine still camera shy [ugly, not presentable] but identical otherwise to this.
Speaking of which, how & where do I find replacement fuel tank caps. They are male 4-7/16" OD thread, what appear 8 TPI, about 5/8" of full thread. Originals were bronze, probably why they were stolen. Once I buy [or make aluminum ones] I'll fabricate a pad locking arrangement.
