New Arborist tool

Rupe

It is designed to push. The bar however does lift very well as you can see.

M.B

Its appeal is subjective to the observer/operator I suppose. Its main value is the mechanical advantage, like a winch. Obviously for situations where notch cuts on longer sections are not preferable, or possible, due to confinement perhaps.

I was advised that 'acceptible manual effort' for such a tool should not exceed 25 KGF. I designed it at a 15:1 ratio. So to push a 300kg section requires only 6 KGF of effort, finger tip stuff really. To push/slide these sections manually, while strapped to a tree, would require far more effort and discomfort than if you used this tool. At 25 KGF you'd be pushing a section of around 1200kg! Point being, there is a limit to what a person can physically push. However, if you like pushing big logs then good on you.

This tool is a luxury, not a neccesity. There are plenty of ways to get the chunks off ie bars, wedges, pull lines ect, I'm not going to knock these methods because people have used them effectively for years. What I will say though is that the blockdriver method is very safe and incredibly easy. I wont use the term ergonomic because I'm sick of hearing it, lets call it labour-saving.

I dont really want to get into a big debate about whether or not its needed or who's strong enough push off the biggest sections without using it ect, that wasn't why I posted. However, I personally believe that by providing climbers with mechanical advantages (which this does)can only be a good thing. The feed back from users so far has all been very good, so what more can I say. We'll see what other feed back comes in after its been launched. Thanks
 
The culture across the pond is different too, we have a bit more space to play with over here and don't quite as often have to chunk down a spar, nor for as long for the duration of the removal.

Day in day out it might be a tool to provide a bit of a welcome break.

This is a civil rebutle of Butch, who isn't wrong in his observation, but is neither right. Maybe less anger and hate for the TB cafe AK?
 
AK is just a passionate man with little tolerance for fools. Please excuse his outburst but it came from the heart IMO.

ContractClimber there is no doubt about the tool, at all. Just power on, feed the thread thru the needle and continue to sew the scene. Your ingenuity will be recognised and rewarded. We need to get your real name out there ot the company name etc. Do you have names for the company, product etc? Are they rock solid and protected? Like what's to stop anyone just copying it and calling it the same? What's to stop a texan oil baron making them in Etheopia for nicks and buttering up Stihl for sales exposure and branding?

Also jump into bed with the arb associations, ISA etc, get advertorials written in the trade mags if you can.

Is there a comprehensive website for it? That's an area I can help in, you'll be extremely surprised what I can do in the SEO dept. I have taken sites from nowhere to front page on Google in less than 2 months. You want exposure and success? This area you have to think 2 months ahead, if you want a top ranking site by Easter start work now. I can help screen the chit from clay, been around long enough, and have some pro's backing me up who get results so I get my advice from the source. It aint free though, coz we all know you get what you pay for. But it is around half price of what you will pay elsewhere and the results will be better.

The making of this device is the easy part. Like a great businessman once said ... "who can make a better burger than McDonalds? Anyone, but who can build a better business? not many."

Love to help anyway I can, no-one would ever know either just like a ghost in the machine.

PSST: have a look at this link http://www.google.com.au/search?hl=en&am...=cr%3DcountryAU

I am third now on Google, a few of the sites behind me have pros working on them to try and beat me, had you have run this search in October2005 I wouldn't have even been in the top 100 pages. The sites above me have been there for years. I'm a competative bastid with a brain like a sponge, new tricks just slip in, and the guys I work with HATE being second best, they are winners.
 
CC Dont forget to think outside the box. You may find another market for it for added sales. Any ideas to help him out. Show it to as many as you can

Thanks for the encouragement. The copying issue is sorted. Patent law is international, a breach would have implications not only for a manufacturer but also the retailers down to the end user of the copy. Not something you want to be on the wrong side of.

The marketing is mostly down to the retailers, I have an agreement with some very respectible ones which will hopefully give us an advantage.

Whilst I really appreciate all the views and comments, the main purpose was to hopefully get some direction on the certification process for America,(if it is infact applicable). I am suprised that after 300 views, I'm no further foward. If knowone can actually advise me on this sticking point then please just let the thread die for now, at least until they're on the market.

I'm sure you will all agree that an opinion based on something you see on screen or grasp in principle may differ from one formed after actually using it in reality. No offence meant, but please try to reserve judgement until we get afew out there. It makes sense. Sincerely, Reg

But that's what trolls do.
 
MB, he's just a passionate man expressing himself, they are just words, did you not hear of sticks and stones?

Also, did you not see the mans history shows a behavior of hit and run, then he comes back and edits or deletes his posts. Now would a genuine troll do that? Why don't you go ask Doc what that type of behavior is? I see it as just a guy jumping up and having his say ... then reading and feeling different about it later and making some amends.

No harm done, if you had kids you'd be used to that behavior and certainly still love them.... bear no grudge the man is behaving that way for the right reasons.

I wonder if it has an application in structural collapse. I have a connection with our regional structural collapse team and this may be an items it can be used for. Please forward me everything you've got on this and I may be able to pass along the marketing!!!

I don't see the appeal. Just push the chunks off! Why pack extra stuff around that isn't needed?
I must be missing something here...

PEOPLE! may I draw your attention to the above quote by MasterBlaster?

He is an anti-progressive/anti-safety treeworker.
This person runs his own treework related forum.(The Treehouse)

He is doing nothing whatsoever to improve safety in our industry and openly advocates the use of a chainsaw one-handed as well as lowering branches using the tail end of his climbing line.

ContractClimber has invented an ingenious labour saving device that is designed to make our job not only easier but safer by reducing stress loading on our spine.

Now this MasterBlaster person who is in a self appointed position of responsibility has decided for all of us that it would be a lot better to just, "Just push the chunks off" 200/400kg chunks!

If MasterBlaster could pull his head out of his navel for one second he might actually have something constructive to add to our discussions.

As a teacher - he is a failure
As a mentor - he is a failure
As a pseudo Luddite he is an outstanding success.
 
Flippin heck Reg, thats a bloody marvelous gadgit. I actually liked your modified felling bar best of all.

Not a tool I would use much myself, but on occasions It would be invaluable.

Are you sorted for manufacturing?
 
Thanks Edd.

The first order is actually late, hopefully will be complete this week, but should have been ready before xmas.
Early teething problems perhaps, you've got to expect that sort of thing.

Nothing is set in stone though, If, after this order, I suspect they are not reliable, I'll go elsewhere. Meeting the deadlines is obviously imperative. You wouldn't believe how many companies Ive been to that just dont want to know, or dont want to work perhaps.

In the first year I had a couple of prototypes made by some local companies, the problem was they would always take short cuts as opposed to following the instructions on my drawings. This was done without crediting me for actually drawing things a certain way for a reason, so in fact they were flawed upon completion. Really f----- anoying.

In the end I kitted out a small workshop at home and learn't the skills needed to fabricate a prototype myself.
This also gave me the freedom to experiment and make changes as and when they were needed. The point is, (and was my argument with all the engineers)If I can make them at home, surely its a sinch to a proffesional. Its just a hand tool afterall!

I realise Ive gone overboard slightly in answering your question, but there is a lesson for anyone considering a similar venture. Patience and perseverance, pleanty of them, question all the fees, as your no longer dealing with your own kind. Thanks
 
Reg, I know exactly what you mean by things not coming back the way you want them!
If you need help, We use several several guys round here who do that sort of thing.
My cousin is the chief Exec at DMM carabiners, and one of my suppliers does a lot of their cutting (high pressure waterjet), a distant relation does all their coatings and finishing, and another cousin has a precision engineering works.
Have you done the drawings by hand? if so, I suggest going over to CAD or Solidworks. If a supplier does not meet the spec you laid down, send it back and refuse to pay for it.

Try to have 3 different companies making the components, so no one company can pinch your design.
 
Edd

Thanks, that might be usefull. The drawings are on CAD although Ive since been told INVENTOR would have been better. The copying issue is covered under the Patent and Design Rights and Copyright, so I'm as safe as I can be in that respect. I may PM you about the other stuff after I get this first batch out. Thanks again. Reg
 
Autodesk inventor is what I use. Its CAD design for idiots. It has a function whereby you can print an engineering drawing straight off.
 
Ed

The software I refer to was in 3D, with the abiliy to rotate the object, remove and even look inside components. A designer gave me a demo of an engine he'd made, for future reference. It was impressive, I'm sure he called it INVENTOR. Does that sound like the same thing that your refering to?

Re. Your earlier comment on the lever bar, in case your wondering how its odd shape came to be.

It is obviously as important as the Blockdriver because with out it you have no method. At first we tried the traditional style shape and action of the felling/pry bar type. Being that I am not a big fella I could not lean back far enough to gain sufficient leverage to raise the load to the required gap. Nor could it offer stability or the 'hands free' option of the locking pin.

Sure you manage, just about. But for anyone who doesn't know, you're legally obliged to make provisions for 'potential hazzards' and 'forseeable misuse'. This must all be reflected in a 'risk assessment'. Failure to make these provisions could have dire consequenses for a designer should an operator ever get injured. These things must be idiot proof.

The lever bar on the footage provides the operator with the most economical method to aquire:
Leverage - (torque, comfortable work positioning/posture, two handed operation),

Stability - (the lever plate actually has two points to dig into the wood).

Safety - (the locking pin secures the load and enables the user to safely insert the Bdriver with two hands).

Just in case anyone was wondering. Reg.
 
600? I'll continue to use a pull line, or a crane, or even a wedge. It is techy though. AxeNot, come on, old school does have its place. MB doesn't promote doing anything stupid. Improv is the name of the game sometimes, and really how often do you push 400lb chunks? Don't start a fight because one's opinion differs from another. It looks like a cool idea but I doubt it becomes standard on everyone harness. Oh yeah, dont assume since I surf the treehouse I'm a cronie of MB. His site is valuable as well. Maybe you should temper the BS a bit.
