Good day folks. I thought it would be interesting to strike up a conversation regarding DOT legal equipment. What I mean by this is in
regards to load Securement Devices.
I ran into a situation where I was hauling a tank on its side and I needed to secure this tank to the trailer. The tank would not roll side to side
because it had feet on it, but, of course I still needed to secure. At the time I didn't have any shackles and I wished I did, but, later on, after thinking about it, I wondered if Screw shackles were legal.
Can anyone find or know what is legal regarding these types of devices. I wish I could find Pin shackles where a Cotter pin secured the pin, but, I have not seen these in larger sizes.
What do you think..
Please add other devices you can think of as well. Thanks

Yes shackles are a legal load security device, as long as they have WLL (Working Load Limit) markings on them and are not exceeded. I use wire to tie the "screw" from backing out.
I also use some short soft crane lifting slings, again they have WLL tags. I use these when hauling large cranes & excavators to go around the pins where the booms mount so I don't damage the pins. I basket them, attach a shackle, and use a chain on the shackle to to binder. All within the WLL ratings, therefore legal. -
Yep, like Heavy Hammer stated. Shackles are legal. Just make sure the ratings are stamped on them
I use them on certain rig pieces I move. Makes tie down alot easierMudguppy Thanks this. -
Your farm stores will carry the 6.5 ton screw type shackles with the WLL stamped. Be mindful, not all the clevises will have the WLL stamped on. The problem with the .5s is the opening is only like an 1 1/4 inch. You will need bigger clevises. I picked up 6 9 1/2 ton clevises from that trailer place on Mines Rd in Laredo (they also carry your big machine hooks for 1/2 inch chain with the WLL stamped on ).

You can get shackles with a nut bolt and a split pin that are rated if you are worried about it coming undone

Spot on. I use two 20 ton shackles attached to the rear of my Fontaine RGN (where the 4th axle would normally pin on) to secure the rear chains on our 53-ton track grinders and 50-ton chippers. I don't need the pin-on points since we use a spreader bar for the forth axle, but the holes are too small by themselves to fit my 1/2" chains thru.....I can probably dig up a pic if anyone would like.... -
I agree regarding the WLL. When ever possible, I try to get load securement devices that have a higher WLL than what I will need. This way, 1, they won't wear out, and 2. better safe than sorry. I also noticed some of the shackles are stamped china and not a mfg name. Sometime kinda scary. Any difference between stainless steel vs Galvanized other than the higher price?? Still obtaining the proper WLL??
Mudguppy, any pics?? -
Stainless steel has very poor tensile and shear characteristics. i would personally rate any SS load security equipment at precisely the same rating as my dog's non-welded links on her choker chain collar!

I was asking because I thought the Galvanizing process also weakened the metal.
Thanks. -
I don't know the degradation factor, or even if there is one, of galvanization. I know that galvanizing uses an electro-plating process in a chemical solution, similar to chrome plating or anodizing. I don't imagine it's very much, as I know of at least one trailer manufacturer that used to (maybe still does) galvanize the frames on their flat & step decks as it would stand up better than paint in harsh climate and salt covered road conditions. If it weakened the material too much, the frames would fail, and they don't seem to be
