175 Ton Knuckleboom

MikePoor · May 16, 2009

Yeah 6t56 It's 1 of only 2 in the u.s. Ranger posted photos of the other one. It's owned by a crane service in NY. I've heard that crane is driving his competition in the ground. Because of all the knuckles he can do jobs that crane services can't do or would need a much larger crane and set up further from the bldg! In fact he's doing so well with it He (Mr. Pinkus) just bought an EFFER model 2200!!! Hey Jamin! I've always wondered about that too! I can see the homeowners point of view, but does the pilot of a 747 call you at home to ask if he can fly abig hunk of metal over your house?

all The logs from this Celtis in 1 pick

used a hook on the end of a sling to drop down through the trees to the log bed

Great point. I'll use that if someone ever gives me a hard time.

And what was the diameter of the Hackberry?

And does your K-boom have a scale on it? I can't remember if that was communicated...

Hey mike,I was looking at the chart for your k boom and if im reading it right your capacity is the same at 0 degrees as it is at 80 degrees.And the only thing that dictates your capacity is boom lenght?Is this correct?

MikePoor · May 18, 2009

Yes that's correct 6t56. unless you have the jib knuckle over center (then you only have to deduct a small percentage) This is another plus for K-BOOMS

Awesome picture Mike!!! What's the side reach like on that beast!

classictruckman · May 18, 2009

I see it as a down side because you can't boomup to put yourself in a better position.

MikePoor · May 19, 2009

Hey Classictruckman, how's it going? I think you misunderstood? you can still boom up with a very large load when the jib is overcenter. (somewhere in this post there is a photo of the main boom flat, the jib 20 degrees over center & picking a 6000lb log at a 100 foot radius- the post says "playing with the jib" Hey Ranger! It's 130 feet. It will pick 3000lb plus at 120 foot radius.

Spiderlegs & little Platanus stem = no movement

MikePoor · May 19, 2009

Dunk in the chipper

MikePoor · May 19, 2009

One of the top leads

Great pics Mike!!! The in tree perceptive is great!!

Looks like you're liking the Tachyon!! I remember Wagnaw over at tree house posting a couple of pics of the tachyon splice he did for you. Same one you're flying in the pics I think.

Jamin_Mayer · May 19, 2009

Hey Mike. When you are setting the slings do you use a slippery running bowline to take up slack? I tried to guess what you used on that Sycamore photo.

rangerdanger · May 19, 2009

Hey Mike, are you expanding?? I noticed 4 ground guys in your second pic. Just curious.

Mark Chisholm · May 20, 2009

Real nice Mike. BTW, we need to get you a Rope Guide and a single sliding ring attachment for the harness. Then you'll be really loving it!

classictruckman · May 21, 2009

This opinion is coming from a stick boom operator, but the fact booming up doesn't improve your capacity is a down side to me because if you are out near the limit with a stick boom you can notch the pick towards the crane and make it vertical by booming up and improving your capacity.

BTW 3000lbs at 120' is very awesome.

Think of it the other way. A knuckleboom doesnt loose capacity as you boom down. That is the advantage over a stick crane.

I pulled a stick to me the way you describe yesterday(although not near capacity) to make it come off smooth. We can still do that.

classictruckman · May 23, 2009

Can knuckle booms stand the added wear on the booms to retact under load to perform the same notching and lifting to improve the capacity like a stick boom?(retracting instead of booming up to bring it closer)
