Thread: Worst Shop Day Ever

Thought I would share this YouTube video I came across, it was linked on the Jimmy Diresta channel, I'm not sure if this could have been prevented, he says in the video comments that the cable had a fibre core that had absorbed moisture and rusted the cable from the inside out, maybe careful storage and periodic replacement could have prevented this, otherwise, just an unlucky accident

Pants staining stuff - thanks for posting.

at least Brian wasnt hurt

A lesson for us all, particularly in respect to those who have home lifting gear.
Regular qualified inspection and replacement of lifting gear is mandatory at an industrial level,but at home some of us at home might be tempted to avoid an otherwise expensive process.

I have a relatively light lathe to move ( Chinese 12 x 36 ) but will be using a brand new 1 ton sling when I move it from garage to shed.
After 3 years the paint on the floor has cured enough.

I saw that video the other day, pretty scary.We have to daily checks on our gantry cranes at work and they get a major 3rd party inspection every 12 months. All the crane cables i have ever dealt with have been heavily greased with moly disufide grease for lubrication and to prevent corrosion, that cable must not have been greased for it to corrode from the inside out.

You are absolutely correct, Snapatap.

Its not bad luck and we should not be sorry for him. Its a highly dangerous operation and he had not even observed the basics. He is an amateur and never took the trouble to understand the potentially dangerous equipment he was dealing with. Its only sheer luck that we were not watching someone seriously injured.Just look at where the man is standing tells me he does not have a clue.

If you watch the video he uses an endless chain which powers the overhead pulley set. To me, that indicates a really old set up. It is blatantly obvious he who was never properly trained in lifting gear safety and understanding the need for inspection / maintenance.

I went back and watched the video in its entirety. There is a close up of the break. I have a some steel slings which are never used for lifting and the failed cable is the same rust colour as my slings which have not seen oil in 20 years or more.The fibre he speaks is used between layers to avoid friction between strand layers and the failure has nothing to do with the fibre holding moisture and again that alone points to the age of cables as I think the current ones have a plastic of some sort.

See this about how cable is made https://www.youtube.com/watch?v=eDVf71xd2cQ

That cable has not seen grease in decades.

Coming from a crane operator and rigger background I can see why that hoist rope broke. Wire rope for hoists/cranes in my experience do not have fibre cores. Fibre cored wire ropes are used for slings, NOT hoisting. No doubt at some stage of the crane's life the original hoist rope was replaced with a much cheaper fibre cored one.

It is somewhere around 12.5 tonne that drill. So not exactly Hercus 9A weight.

I watched the video before reading everyones comments, so didn't really know what was going to happen or when. I needed to change my undies after that!

Crickey!

Anyone watch the preceding video of where the drill was picked up? Listen to the trailer groan as the drill is loaded onto it. I wondered if the moving setup was really up to spec.

I have watched a few of Brians videos. He has some huge machines to move into that workshop. He mentioned 3ft thick concrete at the rear of the shop where one of the biggest is to go.

I would not have said he was lacking in knowledge etc, but that cable obviously should have been replaced. It is a very old hoist and the condition of the cable was unknown. I did see a video where he tests the hoist by lifting the rear of a tractor.

What you posted has been backed up on another forum. Never use fibre core rope for those applications.

Probably one other thing is I am not sure I would want to meet someone on the highway pulling that weight with such a lightweight vehicle. In Australia I think it would be go direct to jail, do not pass go, do not collect $200. He is probably pulling 15 tonne.

It was a pretty dodgy operation for sure. Blind Freddy could see it was pushing everything way past what it was intended for.

I fully agree with you.

Just dead lucky he wasn't hurt.

I hadn't actually watched the video from the beginning, scary stuff all right, he's lucky it let go when it did and not when he was working the endless chain at ground level and under the thing
