DIY GRCS

The winches for  £700 will be for sailing and not industrial use are they not ? Although I am not actually sure the GRCS is CE marked so void in the UK should the shit hit the fan so you might as well crack on . Out of interest where do you get the winch for £700 as I could do with one . 

The winches are the same. They don't have specialist ones made up. They do ones that are CE marked and EN specified as some are used for winching dingies onto yachts etc so become lifting equipment. The winches used on the grcs are just harken 2 speed self tailing winches. Up to you about which one you get spec wise. Have a look on their site. Most of there range is sub £700

Heres mine was using it to raise timber away from a clay tile roof, made the job far too easy groundy loved how easy it was for everyone involved. 

Only had one ratchet on as what was lifted wasnt huge and no negative rigging 

 

 

He easily winched and tailed the rope, i have designed a mk2 which when i build i will convert the winch to self tailing. And when im happy with my pair I'll get them shot blasted and galvanised 

 

 

I do also have a company in mind to load test it all

This is spot on as an observation. One of the first thing taught me in economics was the financial benefit benefit of a monopoly and how in the absence of this to create a false monopoly.

 

It also makes me think back to the time of guilds and how that they suppressed innovation.

 

I experienced some of this from the 70s when I could approach a landowner, get a felling licence, buy timber and sell it to a sawmill, then Forest thinnings came along and negotiated exclusive rights to supply mills, then H&SaW bit and we had to pay money to the into the NPTC pyramid scheme, then FSC...

 

Just layers of middlemen feasting at the table whilst contractors grovelled at their feet licking up the crumbs they dropped.

and thats why we used to knock oor pans in for £7.50 a ton.

Do they not have to be destruction tested first? I was advised this years ago and it’s what always put me off making my own.

Well, actually no, it should be tested to working capacity and then to its max test capacity dependent on its specification. 

 

 

 

 

 

Something like this i believe. And Leibherr should know what THEY  are doing.........  ?    K
