I need some heavy haul reference materials for securement.

Ignore the number of tiedowns per length. It does not apply to machinery.

For heavy machinery over 10,000 lbs you need a minimum of 4 tiedowns along with a tiedown on all parts that can raise or lower by hydraulics. Beyond those minimums you must meet 50% of the items weight in WLL.

Your math of 8 x G80 1/2" chains is otherwise correct for the 87,000lb excavator. Probably call it 9 for the one over the bucket/stick. Technically that one counts toward the aggregate WLL but some cops will argue otherwise.

 

Says Gross Weight LEGAL right on it. So what ever the max in Nevada for axles and gross is what you can run with that permit. It does not allow overweight.

 

To question 2; No, you still need to meet the requirement. It all has to do with the number of axles on the ground. If your truck is registered for 80k gross on 5 axles you can’t go over that. You need to look at the state regulations for maximum weights per axle or multi axle, then look at what your cargo load would be.
As mentioned previously, your state trucking association could help you. They will want your company to join. They should have people knowledgeable in the state’s regulations. That’s what they are supposed to do as part of their charter.

 

This’ll be a bit winded but, I hope informational….
Here’s my 2 cents. 1: Nevada O/S permits cost 60 or 70 bucks for weight, width and height. Get it for max weight and 12’ wide (you can run during hours of darkness up to that width), 15’ 6” tall ( over that you need a pilot car in the Vegas Metro area). 14’wide only allows daylight movement
2 let’s say you are moving an articulated piece of equipment that weighs 73K (run of the mill 623G and older) You technically need 8 tie downs because it needs to betied down like it is two pieces. Grade 70 transport 1/2” chain @ 13’ lengths out 10’ and have a few “shorties” 3’ ish made (if you’re in Vegas I suggest Silver State wire and rope, great dudes I shop there often). You’ll need 1/2-5/8” binders you get the full WLL out of your chain with these.
3. If you aren’t going to pull anything that heavy. 3/8” chain (grade 70) is also super acceptable. These dudes that run around with 5/16” are looking to kill themselves or someone else.
3/8-1/2” binders for the 3/8” chain.
Rule of thumb, if it articulates and you have a lock bar, treat it like one piece and four corner it(weight does play a roll in number/size of chains!) over 50K use 1/2”, under? Use either 3/8 or 1/2, whickever tickles your fancy.
On a 140 blade, I put 6- 3/8” chains on them. (I’m a rebel I don’t secure the ripper)
A 966H, I’ll lock bar it, 4 halfies and throw a 3/8” on the bucket.
A 336 (roughly 82K)I will four corners the tracks with short hellfires and binders and put a long chain in the middle on both sides and. 3/8th on the boom.
Hope this helps.
