[SteveBullman]

anyone use this method?

I agree with Steve,Great idea.

I saw that as well and was amazed that I hadn't thought of it myself. I usually pound my brains out setting wedges. I actually grabbed my 12 ton bottle jack, made a piece of plate to go on top of the plunger, and threw it into my chiptruck for next time.
Great idea, methinks.

Their is a chapter in G. Beranek's book " The Fundamentals of General Tree Work " that deals with how to use a tree jack, good reading if you can get the book.

Husqvarna used to sell a tree jack but not the type we are talking about.

Ive seen the photo aswell...Who is it in the shot..

I have had a 1942 "twiler" jack for years, amazing bit of gear...

They were for lifting houses up ..It has a low foot and a high lift spot to, its about three feet high and lifts from an inch from the ground or the three foot mark, then by rotary handel you wind it up the whole thing can raise to 5 feet

I use to use it lot on the huge ironbarks. For post ripping and slabs( wedges wont move them to much) they just sit there...The stamp on it says 10 tons

I recon they did the same SWL as we do now with rope..seems unbreakable...AWSOMETOY..

there are more modern ones now , works on a straight handel pump up bar we call them "wallaby jacks" (still works on leverage)

That little 20 ton hydrulic would be great!

Hydraulic jacks with the cylinders connected to the pumping units via hoses are arguably better-suited to the task.

The Rural firefighters have one in the work shop in town.A porter power, Glens..AWSOME bit of gear there to..being remotely operated you can use the cylinder on any angle. the little 20 tonner wont work for example on its side..

Personaly, unless its changed conciderably I dont like it for trees at all, to long and thin for starters then theres the foot issue, i reailize they have many attachments for stability but to much messing around with all the attachments...and you might need two people to get it in position, one to hold one to pump!

Now for straightining out a car frame on a "may" rack or pushing Bushes or bearings into a rockcrusher , its the perfect tool
And finaly I could buy 5 Wallaby jacks for the same price over here...There about a grand for the basic set up..my0.2...

How ya going anyway Mate, proberly lots better when your elections over, christ even we can't escape the hype all the way over here....How do you all put up with it.....Derek M V P

 

[Derek]

Hmmmmm said all that then looked at the site...

It doesent show the bigger models , but wow there no where a grand are they...Ill have to go down to the station later and get more info on the one we have!

Then price that one in Austraila....Still think i prefer my others ..

I can't recall who that is, but I know they are a member here, and I think they are from Australia or New Zealand. Timber Mcpherson, maybe?

id say its timber,thats actually pretty dangerous,ive done it with truck jacks all they want do is spit out

 

[TheTreeSpyder]

Dent's "Proffessional Timber Felling"; doesn't go into jacking too much, mostly for back leaners. In fact, a jack is mentioned on the first page as part of safety equipment.

There are some high end Silvey's listed one of our sponosors -Bailey's (Catalog) under : FALLING AXES, WEDGES and TREE JACKS

Gonna have to try that myself!

Another reason I like the jack on the ground, and its not critical where you put the backcut the jack adjusts. I put a special cut in it to accomadate it just a lil notch realy.. did you try it on gums Aussie? they would want to come out ..The old ironbark wont split with a 20ton splitter got to take it off in pups..

Silvey makes a good jack they call it their treesaver, its a 45 ton no hoses, relatively light and works good up to about 4-4.5 foot trees. bottle jacks dont have the lift nor is the plate setup right for trees.

Here's another pic I found of that same tree...

 

[a_lopa]

climb up put a sling in and turfor away thats IMO jacks are asking for trouble

 

[MasterBlaster]

Jacks appear to be used mostly in non-climbing operations.

big elm swamp gum,or there abouts

The photo gallery over at http://www.madsens1.com/ has plenty of jack pics if my memory is working right.&nbsp; Seems you'll want to opt to "view image" in the right-click stuff if you want to see them a bit better.&nbsp; For some reason they opted to resize many of them via browser HTML directives and that usually doesn't work well at all.
