Reitnouer coil racks

For years we only used 2 regardless of the coil weight. But they were a lot heavier duty than the truck stop specials. Then guys started using three if the coil was 60" wide and over 40000lbs. Now l use 4 if the coils over 50000lbs. That's for suicide coils and the coil bucks are on the frame rail. I've only seen one break. We made some out of leaf spring material and it broke beside the weld. We figured the weld made the steel brittle right at that point.

 

The concept is subjective. Some carriers have their own rules regarding the number and such. As far as I know, and could find regarding regulations, you're looking at minimum of 2, just to keep the timbers in place at each end, and that's basically their whole purpose. As with all securement, more is better as long as it's not in OOS condition. More is probably better as special k mentions. Figure whatever the coil weighs, it is pushing down and outward on beveled coil racks. Do you really want a coil weighing say 30,000 pounds being pushed down into that timber, which displaces that weight by spreading it down the timber and away from the coil to be under secured? I used to use minimum of 3, just to make sure the two ends stayed in position, but on the off chance that one or the other shifted during transport either through emergency manuevers or some such, if one of the coil racks came loose while the coil shifted, that there would be one more at least to take it's place holding the timber together.

As far as I know, there's no federal regulation requiring a certain number, or a certain rating, but if those are rated by the manufacturer, then you should figure how much is needed at 2 minimum and refer to the manufacturer's recommendations. The interesting thing, though, is like belly wraps, rated coil bunk WLL is useless as regards aggregate WLL for holding the freight as it's more of a safety aspect, than a rated restraining tool. If they are rated, then I'd refer to the weight of the freight in the timbers and add accordingly, since that weight will be bearing down on that timber/coil rack and pushing outward. Start with 3 sets of coil racks or your J-Track version (meaning 6 total) to start and use as many as YOU feel comfortable using to keep the timber or coil in position.

 

Not claiming I ever did it right, but I’d use 2 on each side sometimes I’d use three. Never had a problem. I also quite often put these blocks in the j track and use 5x5 beveled lumber. Works really good for big coils and the coil will set further inside the rack.
