They're called binders. They are a steel cable with chain on the ends and a (I don't know the name of the parts)with a ratchety thing on the end of one. They use a cheater bar on the end of the ratchety thing. If the driver is wise, he/she will drive a ways and stop and tighten up the binders because the logs will settle. They usually run 3 per load and have to have all logs secured or covered by one binder.
They'll coil up the cable and throw them over the load, so you want to be out of the way when in the loading area. There is a difference, in the Okanogan area, they loader operator would pick up the binders with his machine and place them over the load. They all said this helped lessen injuries.
I'd guess you can purchase them from places that sell rigging or even trucking equipment places. And no, the stacks at mills are not bound by anything.
If he is gonna load that high...why take off the slip on bunk extensions. We get away with ALOT of stuff here but that load would not be unloaded on Weyerhauser property. no higher than the front bunks.
