Load Securement / Rubrails

Machinery securement is the only thing that I have some experience with on a flatbed. Will pickup from rental places for use on jobsites. Usually at or under 10000 lbs. we do smaller tight spaces usually in the city core.
All small truck stuff though, still use four chains/binders on them, lots of city stops and starts and idiots cutting in and out

 

So, you have the general idea of a proper 4 point securement. The bigger machines operate on the same principle. You will have your 4 point to prevent shifting, but the rear pull WLL has to cover 80%, not 50. Another 2 points of the machine articulates, and every attachment (booms, buckets, blades, rippers…etc) requires its own tie down. Can you draw a securement diagram securing this?

 

It’s on the way, finished feeding the kids

 

Something articulated like this, I would tend to treat it almost as two vehicles. Once in place on deck would need to get the lockout bars in on the articulation point to keep it straight. Bucket down and flat to the deck. Starting at the back counter weight two chains two to the right (one more angled than the other) usually a hoist lift point after the counter weight piece. That gets two chains as well, one to forward edge, one to rearward edge. A chain each direction at the axle. At the pivot point it gets a little busy, 2 chains from rear of pivot one forward to side, the other back to side.
As stated earlier the articulation bar is secured to lockout the pivot.
For the front half, starting at the pivot 2 chains 1 forward to side the other backwards to side. Usually a hoist point ahead of the pivot for 2 more chains, again forward to side and rearward to side. 2 chains the front axle in the same fashion ( one forward and one backward).
For the bucket arms I would try to go from the large cast piece that dumps the bucket rather than the arms themselves to avoid racking the arms.
I would secure the bucket with a chain from front of bucket, over the top and back down to the side near the edge wear it won’t bend. And then after all that, that’s just one side, start the other side.
I am no artist, here’s a very rudimentary drawing of my thoughts on this

 

Forgot to mention, thanks again

 

You’re doing well.

What if you had a bowl (like a cereal bowl) that’s 8ft diameter, 3 ft tall, 11000lbs, stainless steel? How would you secure it?

 

If I can get upside down it is sturdier due to the shape. Would have to block underneath to protect the lip. Many blocks to distribute the force evenly. Would try to use widest strap available to me to spread out the pressure.
One strap just each side of the centre to snug it to the deck, not too tight yet. Then in turn one over the mid point of the curve finishing forward ( the other backward) of the first two straps. Then in turn the last section by the lip pulling away from the edge and pulling the edge down and forward. The front one doing the opposite. Tighten them fully in sequence after they are all in place.

 

If It had to ship open side up, I would need to get to work with some carpentry tools to build a crib for the front and back of the curve with smaller sections for the sides. Would really prefer it turned over, much stronger for a bowll

 

I’m no engineer so I have no idea what this scribble scrabble in the last few post means. . Just busting your b*^ls @Carpenter Scotty .
