Palfinger Kboom Improvements

You betcha! I've literally spent hours talking with Kboom owners (over the phone, emails, and even texting).

I've talked to both stick boom owners and Kboom owners. Some have also been kind enough to let me see their fiancials. That has been helpful as well.

I was sold on the idea, the first time I saw them being used for tree work. I only saw the idea about 8 years ago. But, instantly knew Kbooms would change the way tree work will be done.

And seeing the new purchases, with some of the Tree Buzzers, is encouraging and confirming that this will indeed get people to rethink tree work. (Similar to the SRT revolution).

But, I do think Palfinger has put a lot of R&D to a technology other Kboom manufactures aren't doing (yet). And I'm impressed with them taking that step in doing so.

And their system confirms the another advantage of a Kboom over a stick boom.
 
I feel Effer has put more effort into the strength and capabilities of their crane itself. Their steel is lighter and stronger, and hydraulics are powerful and operate smoothly.

The SCS, on a Palfinger, I'm sure is an expensive luxury and a substitute for common sense. Most pics in tree work are between 500 and 1500, so if I have to short jack an outrigger, I will make a note to take smaller pieces.

I do not agree and will give personal story later when not using a cell phone in bed.
 
A job a few years ago.

took down a big pine with the k-boom.

the main trunk was large and heavy.

I wanted to just take about a 20 ft log and place it on the bed.

from where the truck was, that looked a little too heavy, so after dismantling the whole tree except the lower trunk, I decided to pull up the outriggers and move truck closer to the tree trunk for the last pick.

The far away outtiggers, weren't going to "be used" so I thought.

Full outreach would have put them in the grass, so I left them short, just on the driveway crushed stone with NO PAD.

I picked the trunk log. It had one limb attached to it.

As I went to lay it on the truck bed, the log rotated and the limb was being a problem. I didn't want the groundperson climbing the truck and slipping. I motioned for him just to wait and I proceeded to set the log off on the outrigger side with short outriggers and no pads. forgot. (so he could cut off the limb).

main outrigger starting sinking to China, suprizingly FAST! I quickly set the butt of the log down and stopped the sinking and possibly the flipping of the truck. The opposite front tire at the cab was off the ground!

I messed up, but luckily saved it.

If my palfinger had this new system, it would have warned me ahead of time and not allowed me to do that.

We all make mistakes at times.

Any program that can step in for those times is worth a LOT!

A system I opted for that our k-boom has is AOS, if i remember correctly. Active Oscillation System or something like that. anyway, if there is a shockload and the crane gets pulled down, the computer immediately picks up the load.

If you watch the manual controls when this kicks in, it looks like a ghost is running them.

This might have "saved me", maybe in the past.

I took an odd shaped pick, had the boom too far out, was pushing the capacity.

the pick, once cut, dropped down a bit and swung out into a further zone, I heard the AOS kick in and pick up, taking the downward bounce out of my mistake. The alarm chimed and showed 100% capacity. It may have kept our truck from going over.... I don't know for sure. All I know is that I was glad for the software and glad I had choose Palfinger.

It was a very hot humid day and I was just trying to get things done.

yeah, it is seldom, but I can make mistakes.

For those times, why not have equipment that can help you out?
 
Yep. We're all human. Well, some are mutants with special powers...

Thanks for that story. It shows that the Palfinger stabilization control system will be something to consider when purchasing a Kboom.

Yes, Effer has a very similar system. I'm glad we don't have it on ours!!

We put two sets of pads under every outrigger... the botten pad bigger than the top. There is no excuse for not putting the correct cribbing/pads under the outriggers. We make it a point to have the biggest footprint possible.
 
My understanding of this system both on Effer and Palfinger is as follows:

When you short jack the outriggers the computer calculates that in the short jacked quadrant maximum reach is "x". The computer then limits boom extension to "x" in all quadrants. This would not be optimum for our work. Today the Kboom was short jacked on the street side and used as a TIP. With this system we would have been limited to our reach on the non-short jacked side. It would have made using the Kboom as a TIP not an option. There is the option of overriding this system, but (in my understanding) when you do so you override all the computer safety features.

If someone has a different understanding I am open to your interpretation?
 
My crane has an anti tip system. Doesn't matter where the riggers are,full or half or in between. The only time the rest of the crane is limited is if a pad lightens up then it slows the crane down until two lighten up. Then you can only move toward a position which will put weight back on the outrigger which is light.

Ours had the same system, if two out rigger go unstable, an alarm goes off on the crane and it automatically stop the crane from extending any further out, but we can still bring the load in or set it down.

I was told that the system that effer has does basically the same thing as what we saw in the video from palfinger. Basically an infinitely variable LMAP, calculating the capacity and limits of the crane at any working area, changing as you rotate, calculated based on the outrigger position. Sounds like a great system, I have never worked with anything that has it on it, but look like this could be the LMAP of the future. I talked with an engineer from Altec about this a few years ago, of the many challenges of implementing this in a production unit, one that seemed noteworthy, was how to control a load, on a glide swing crane, which was rotating fast, when it reached its limit. In many cases stopping the boom instantly could lead to bigger problems. On most cranes the LMI would stop you from going into an overload situation by limiting your ability to increase your radius, but in these new systems they need to control your ability to rotate over the short jacked area. I am looking forward to seeing how they made it all work.

What does dunnage, an ensuring stable ground under your outriggers have to do with a LMAP system, no computer could protect against a sinking outrigger.
Why wouldn’t you want a computer which automatically adjusts your capacity’s no matter how far you extend your outriggers?

I was telling a story and mentioned two components.

One: the outrigger was not put out to the full extension.

Two: a good base was not put under the outrigger foot.

Number one has to do with what we were talking about.

Bite me.

That's cool. Sounds like Effer is one up to date mutha effer.

Do they have a similar AOS too then?

I guess so???
 
Active Oscillation Suppression System (AOS) Palfinger has a patent on this feature and is the only K boom company that offers the operator to operate their crane at full speed IN BOTH DIRECTIONS while having AOS turned on.

AOS equalizes vertical oscillations caused by crane operation and sudden load changes to reduce shock load to the crane and truck. This is not an expensive feature at all it's well worth the money.

Most other crane manufactures have something that is similar but when it is engaged the crane operates slow all the time.

Another new feature we offer is Super High Pressure Lifting System (SHPLS) This new feature allows the crane to go into it's heavy lifting mode and back out on it's own. In the past and still on a lot of Palfinger's cranes you have to manually turn on the HPLS on and off by the push of a button when you need extra lifting power.
 
Very nice of you to join us and add something else to this effin thread.

Welcome new user.

New input is always welcome.
 
My 2004 Ef' 1750 has anti tilt.....now can Palfinger and the others lose some of the unnecessary bulk, get decagonal extensions, improve the welds on the extensions....that's just to start! Then I would have to give them a look. :)
