trewhella winch

[elicokiz]

hi folks ..trying to assertain the pulling capacity of our monkey winch ..always assumed it was 10t ..but there is no rating plate on the machine...should I measure the diameter of the wire rope to assertain this obviously the rope wears through use and gets thinner, so rather stuck with what to do for an accurate rating ..other than contact Trewhella directly? any ideas folks??

 

cheers

Dave

if you can get the model number, or just google trewhella winch and see if you can find an image that matches yours then find info on that.

Blimey!! is that thing still going??

 

Id suggest measuring diameter is a bad idea. it has also had a lot of use so yeah id suggest contact them directly for an answer.

 

you could try and get hold of an old manual?

 

You never know, you might be able to wangle a new one!!

[Arborist]

Cant help you with the info you need but the only info that i have on them is and I can still rember James Boyd saying it at college is if two men put the strain on two men MUST take it off!!!

you could ask monkey d as he has a trewhella and i'm pretty sure he'll know the swl for it. Although as a rule of thumb the statement about two men put it on and two men must take it off is pretty much on the mark. These things bite and can be very unforgiving.

Had a look yesterday, but no plate on ours regarding loading. Some info on the cable hook, but covered over with years of paint. So now unreadable.

 

Will try & recover any paper work from the dusty vaults of scary filing cabinet.

 

Think there may will be a half eaten mouldy eccles cake in there, that's now taken on a life of it's own.

Thanks Monkey-D , i'll be very appreciative of any help, the Trewhella web site does not look too promising but i'll give that a shot too.

I currently have four of the things of various ages and am slowly refurbishing them. I have also been in contact with Trewhella in Birmingham about spares and found them to be generally very helpful - they supplied a operators' manual on request and entirely FOC (although it is a rather "third world" manual - small and photocopied). They still makes the winches and can supply as far as I understand it all spares.

 

However I have never seen any mention on a formal SWL or limit on the pull. I have often heard them referred to as 10 ton capacity, and I think that this is probably a reasonable estimate for a single line pull. The basic design dates from a time when common sense prevailed rather than legislation, and you are unlikely to break a Trewhella that is in good condition unless you are excessively stupid! The manual does IIRC suggest that two men on the handle is usually enough (but I am sure that I have also seen a reference to having more men on a rope attached either side of the handle)! None of mine have any form of marking that states the max load.

 

I am fairly sure that the reason the winches are no longer sold new in the EU is because they don't come with test certificates, CE marks, and all the rest of the things that have superseded common sense now.

 

The most important thing to remember is that however many men are needed to apply the load must be used to release it. This is because the principle of operation is exactly the same as a Hi-Lift or farm jack, and as with the jack the handle can 'run free' if allowed to get out of control while releasing.

Mine is long gone. I'm sorry now, most people here wouldn't even know what one was these days.

 

A four foot pipe extention gave it a bit extra power, unbreakable IMO and we did some big stuff with it.

 

I have a picture I stole from here, but I can't find it now. It was one Monkey-D posted once.
