I really like Brians way of going about things
We had a 10 ton " Yale " chain block come back off a job. It was cleaned down and put back on the rack waiting for the next job. The insurance inspector comes along and finds that some idiot had been careless with the oxy-acetylene cutting torch and had cut half way through one of the links in the load chain ! Least I hope it was only carelessness !
Tyrone, what is the prefered way to rig a decent sized radial like this?

I don't care if it was carelessness, malevolence, AoG, or a micrometeorite, the person who held that torch handle would have been fired with great gusto if s/he was in my employ. That's manslaughter at best, mass murder at worst...
A few weeks had gone by before the inspector spotted the damaged link. We had our suspicions as to which welder was responsible but we never did manage to prove it.
Regards Tyrone.
I don't know if there would have been less machine damage lifting from the base on the tslots per Tyrone's method or the sling how he had it. The sudden stop caused all the damage..., perhaps if the arm had been up a bit and allowed it to expend some energy turning down it could have been lessened but I have seen books showing rigging radials more or less how Brian had his. Tyron's method would be a bit more adjustable for better balance and level hang.
My only experience moving radials we jacked em up and forked under- with a gentle touch on the controls . Last month we rearranged 2 radial drills, a little Carlton and a 20k lb Fosdick Hydraulic- both forked.
In the end it all moves way faster when it goes wrong than you can move, only thing I would have done different in his setup was get it on the floor as fast as possible, seemed like it hung quite a while off the trailer edge.
What does that drill weigh? Around 8 - 10 tone?
The main take away for me I think is that its not always possible to properly inspect a wire from the outside. What does that drill weigh? Around 8 - 10 ton odd? His hoist is running 6 lines of what looks to be bigger than 1/2 cable. I think im right in saying each line will see around 1/6th of the total load which shows how much capacity has been lost to internal corrosion. Will be buying a new bit of wire for mi winch thats for sure
I got a feeling those bent rods and broken motor mount wont be the only bits that need fixing, reckon there might be the odd crack and broken out bolt holes thatll be needing attention to, at least . Saying that, after watching the video again, goto agree that it failed at probably one of the best times, and Brian being Brian, hes only gona learn from it. Best day at the shop ever!
Interesting pdf on wire rope, theres a bit on internal corrosion the end of page 8.
