I wanted to update, been doing it for a little time now.
If I could go back in time and answer rookie me’s questions, i’d say this.
Get 5 chains and 5 binders, don’t skimp and buy the 12’ chain at 5k lbs. Get the 20’ chains. Also, get ratchet binders. They work the best.
Straps get 15 if you have a 30’ trailer. No, you won’t need a strap every 2 feet, but you will get some odd shaped loads that will leave you scratching your head. Also, sometimes the load you strapped down perfectly will move. God knows why. Either case, you’ll be surprised how many straps you could end up using. I had one 12’ cylinder that was 1,500 lbs. putting on 3 straps, 2 belly wrapped , I thought was overkill as I left the shipper. By the time I reached the receiver I had a chain, one broken strap, and 6 straps on this demonically possessed load. Moral, you really can’t have enough straps. They don’t weigh that much.
As far as tarps is concerned, try to avoid it. If they want it tarped, make them pay. If your broker is giving away tarping like a free extra service, fire him/her immediately.
As far as size, a 25’x20’ tarp will be fine. If you need more than that, then maybe consider getting a different load.
