Strapping lumber
« on: Yesterday at 09:59:58 AM »
Hello,

I was wondering if anyone have had experience transporting boules of live edge lumber and best way to strap them? When we are talking about stacked 4-5' wide and 15' long slabs what would be the ideal strap to use, as in steel, woven cord, nylon/polyester/plastic? Width and thickness?

Also, any particular wrapping I can use for protection?

Thank you
Larry

I don't know about what your asking about but that pack size I would be inclined to add a headache rack to the back of the trailer So anything that rattled loose inside the pack will not walk out and land in someones windshield.

The trucking company next door to me always has boards sticking out after transport. kinda scary.

Thanks for the advise but this is for shipping purposes, as in shipping container. These are large and heavy slabs and I just need them to be as snug as possible. I have spoken to a few strapping companies but still wanted to get a professional opinion.

There are quite few people on here with strapping experience. Theyíll be weighing in given a little time, no doubt.

I wouldn't call my opinion professional, but I've been using 3/4" poly cord strap for the last few years around the mill. It works good for bundles of waste slabs, lumber, and anything else I've had a mind to put it on (palletized bundled firewood is another use). I've never had any break, it has a nice elastic effect so it stays tight on irregular loads. I have both the ratcheting took and the pry bar, they both work fine.

For over the road shipping, even in a container, I use only AAR (American Association of Railroad) green poly lumber strapping with serrated crimps.  I have never had it break of come loose and the tensioning tools will pull a pack tight and hold it there.  You can get the stuff different places, but I get mine from ULine.  

I use the Kubinbec style around the house.  I've had it break several times and spill loads here at the mill, so I wouldn't use it where it mattered.

I've used other lower strength "package" strapping and had it break under load way too many times.  The owner of one of the local mills buys and only uses AAR strapping for my loads but use the standard lower strength stuff for theirs.  He got pulled over and got a hefty ticket (Improperly Secured Load) because, unknown to him, a load of boards in his shipping truck had come loose when the low strength bands had broken, and one of the boards had speared through and was sticking out the side of the metal truck wall and could have killed someone.  He didn't even know it had happed unto he got pulled over.  They only use AAR rated strapping now.  The letters will be inked or embossed on the strapping material.

Metal strapping works too, and is legal for over the road transport, but is a pain to handle and dispose.

Here is the result of the orange Kubinec 1/2" strapping failing under load. I was moving this pack of wood and it started to shift.  I tried some corrective action and instead of holding the lumber, the two straps literally exploded off the pack, one of them flying by my head.  If you look close to the rear end of the forklift, you can see one of the broken orange straps laying on the ground, which was how far it flew through the air after it failed.  You can see the other broken orange strap still under the pile of wood.

Thank you for that, very insightful. I will most certainly look into the AAR strapping. Not looking to loose any lumber throughout any part of the transit. By any chance would you know the break strength for the strap?
Thank you

Metal banding will stain lumber.  I haul lumber and brick thats banded all the time, ill hafta look closer for labeling on it.  The brick has no pallet or shrinkwrap, just a few hundred bricks with a few loops of plastic.  I hate those.  Triangle brick has a machine make the packs.  At Statesville brick ive seen hand banding and those suck. 

Im not impressed with my metal bander personally.  I think id be tempted to look for a low cost fabric strapping solution.  Think ratchet strap bulk spool with no hardware.  Cinch with ratchet strap and screw to sacrificial dunnage.  Or build low grade crates.

For most stuff I use 3/4 ton green.

The true test is an actual drop.  The bands should be sized so that if your load of wood is dropped, it wonít come apart.  Iíve done that, inadvertently, and had a whole pack of wood dropped off a forklift that was moving too fast in a turn.  The pack remained intact, although completely on its side and the bands held.  I was able to flip it upright with another machine and reload it into the truck.

So depending of your situation, you may be better off with even stronger material, up to 1 inch wide.  

Now that Iím thinking about, I had a situation last year where I had a pack of mahogany lumber shipped to me from another mill on the Gulf Coast, maybe 350 miles, to my place in a standard LTL panel freight truck. When the driver opened the door, the bands on the lumber pack had broken, and pieces of 2 inch thick, 10 foot long, heavy, mahogany had been playing demolition derby with other peopleís cargo in the back of the truck for a hundred miles or so.  It was a mess.  Iím glad I didnít have to pay for the damage, because I didnít originate the shipment.  

Use enough strap.

YH, fwiw I think the 1/2" strap has only about 1/3 the break strength of the 3/4". I've never broke it but I don't handle anywhere near as much lumber as you.

Interesting comment about liability. Is it still the vendor's responsibility or does it become the shipper's once the load is accepted?
