Re: Trailer safety Q\'s
Bill, if you mean the car haulers that carry many new cars to the dealerships they use chain. The tie down points on the cars are specifically designed in by the manufacturers and tested! Most of the haulers have short lengths of chain attached to an axle going across the truck (actually, several of these). Once they chain to the car, the driver turns the axle with a pipe and it tightens both sides at once. There is a ratchet/pawl to keep it tight.
Same sort of thing in the rail cars. There is even a test called a "rail simulator". Apparently, the rail cars can impose some vibrations and bumps that are not normally seen during driving /w3tcompact/icons/smile.gif
