Some things moving

I have often pondered the need or rationale for 3 axles on a 3.5t trailer, surely 2 more widely spaced axles with suitably rated tyres would be just as stable, and with lighter unladen weight?

So does IW build them purely on demand based on ill-informed folk-story/hearsay  opinions? or because of some specific attribute the 3rd axle provides that I fail to recognise?

Or is it simply a case of being able to loose one tyre(or even 2 ) to neglect/underinflation/misuse/damage/punctures and still be able to drive on?

In theory harder to load badly. I’d say only on the longer trailers. I’ve a ten foot triaxle tipper and it’s almost impossible to load it so it tows well!

 

Three axles also allows you to have smaller tyres and wheels for the same weight capacity overall, and therefore a lower trailer. My Bateson 18’ tri axle does tow well.

Jacking over a backing leaning spruce.

I can tell that i have been spending too much time in my machinery,  there is a definite belly overhang.

Didn't know you had a thread or did videos... 

 

Can you send a link for that jack? It looks class. 
 

Am I right in saying you've cut your jack seat before you've even gobbed the tree out? Never seen it done like that before!

 

Sweet overhang

yep have always put the jack seat in first ,  it has always always made sense to support the tree first before putting in the mouth.

You've deep pockets. Haha. 
 

I just use a 20T off of eBay and does fine but how much heavier is this 30T? Would be good to have knowing you'll put just about anything over. Sometimes have to use 2 20 Tons to get some of our trees over.

What you are paying for is a certified jack designed specifically for tree felling. If it goes wrong you will still be covered by your insurance.

The only tree i haven't jacked over the wood of the tree failed not the jack.

Non tree specific jacks have been used for felling for ages and have finally been recognised by the powers that be.  Provided certain criteria are met the jack falls within the allowed scope - you can't modify the jack but it must have a removable top plate which can't deform and must have a collar attached.

Insurance... I don't have any but I only really fell in big forests etc for one big contractor so I'd guess we are covered from them....

 

 

Maybe I'll push the boat out and buy one of those jacks in a few months.

It's a shame you are the wrong end of the country, otherwise you could borrow it and see how it compares.
