Galvanised v, Stainless

Good hunting on the ex-navy gear, they usually like spending piles of our money on the best /forums/images/graemlins/smile.gif

Punching the ends is a good idea.

I doubt you'll be coming to me for bits. Go to Saville, Spain and drill just about straight through the world, you'll find me when you come out the other end. Out with the Altas's all /forums/images/graemlins/smile.gif

We do use Italian Maggi made chain which is available in the EU (surprise) and the UK. Eyeco Ltd or similar name is the UK people. Don't know them apart from knowing they do Maggi.

If you are looking for good quality chain look here and here

I used to work designing chain hoists and lived close but and would go and watch the chain being made by them.

If I wished to get some low cost chain I would go to a chain hoist /crane service company like craneaid buy the old chain and get it galvernised.

There was a thread about galvernising and heat treatment with cliff and it seems that the temperature that the chain gets to when galvernising would temper the high tensile chain and make it more ductile.

Interesting site but some strange numbers.

Are you sure they still actually make it there?

8mm tested to 1650kg. That means it a G30 not a G40 as listed. A G40 should be 2050kg minimum.

8mm tested to 1300kg means a 2600kg break. The same numbers china uses. A G30 should be 3200kg break.

7mm G40 listed but with only G30 loads.

7mm and 1/4" being the same..... nope they are not.

Wierd.

I must admit I have'nt been there for quite a while and it was a long time ago I was in design of hoists and cranes.

The company I worked in the UK found all kindes of test results but would aways test both breaking loads and calibrations of samples before usage.

Yeap we do the same. Test and suss very well before believing the marketing.

We have been using mostly Maggi chains (italian) for 20 odd years but still take 6 or so random samples from each container and bust them. Never once has any been below what it said and I suspect it could be the boys love of 200 tonne test beds that make this happen these days. We also bust many other chains and bits.... It is bloody great fun unless it goes well below load and you're not ready for it /forums/images/graemlins/smile.gif

Just don't know about Bradney. They have a well respected name in the game but some of those numbers just don't seem to stack up. Could just be a simple case of the web builder entering the wrong ones, there are so bloody many it can make your head spin without much effort.

Worth a sus though.

There is also a manufacturer in South Africa called McKinnon Chain that manifacture for the mining industry.

Can't find a web site but lots of referances on Google.

Yeah a big outfit it is. They also own PWB, an aussie chain maker. I think they have one in Canada as well and could be more, it's part of a big group, Atlas Steel I think it is.

There is a monster a couple of hours south of Moscow that is humougous. They make OK gear especially big stuff.

Serifini Chains in Aussie does a basic range but bloody well made.

Just thinking about it, India?? Never heard of one there but there must be something surely. What weird things pop into your head at times /forums/images/graemlins/smile.gif

There are many out there if you hunt around. Go to china and you'll find a few hundred more /forums/images/graemlins/smile.gif

Just don't buy based on price alone, it will bite you on the bum more times than not.
