Steel rolls roll off truck bed - GIF

[Toolmaker51]

Never seen rolls or spools carried on their sides; only the periphery. Material handling equipment partly due, loaded by cranes/ forklifts equipped with a spike, of course standing is how the factories use them. Can't even recall seeing a flat un-coiler; maybe for wire but presses need sheet fed flat.
Who knows what happened to tie-downs. Would have been at least 2 or 3 through the middle tending flat [least effective] 1 each tending forward and to the rear. Some use lever binders, others ratcheting and specified load chain. Is it possible tractor-trailer left a depot unsecured, or just the tie-downs worked loose?

A second look reveals that both trucks look like they are carrying the same load and the left oneshows no restraints like the right. maybe just left warehouse as cant see any clear traffic lanes . Wouldn't like to be in any car/vehicle in place of the right one or any vehicle behind the left one if starting up an incline.
Here, it is the drivers responsibility to check the load: including its weight & bet same where that accident occurred.scarey how an oversight can cause havic/death.
