Looking for a 90\' boom , Questions on Knuckelboom

Greetings,
I'm looking for a crane with a 90 boom.
Mike Poors Knuckelboom work is really something. What is the downside to a Knuckelboom vs. a standard boom? The upside seems obvious.

Thanks
 
Re: Looking for a 90\' boom , Questions on Knuckelboom

hey 1914, i posted some of the advantages/disadvantages (pros & cons) of knucklebooms vs. stiffboom cranes on pg.4 of "more fun with knucklebooms" but other pros are: less swing= more control when working between bldgs.(you can direct the pick to go with hinge or the todd k. step cut/shelf cut) and there is a about a gozillion attachments you can put on the end of the boom, etc. intial cost is the biggest obstacle. you need good credit and money to put down. tell me more about what you are looking in a crane, i might have some ideas that might help. my 1st crane was 92' w/82' side reach (840lbs.) it was o.k. but to light for most tree work (unless you could close)

Greetings Mike and thanks for the responce.
The reason I'm interested in a 90' stiffboom is many of the pines I work on are 120+ feet. Currently I have to climb and limb off much of the canopy or often leave 65'of trunk to keep it from flipping.
We live in Ecuador 9 months of the year and do secular work for three months here, mostly around hurricanes. I want to optimize my productivity while I'm here.
I've called Opdyke and others who see a lot of cranes, and most only had dealt with 40' to 50' knuckelbooms.
My credit is good and I've put $60,000.00 aside for the 90' crane whatever kind it is. I'm pretty sure that wouldn't even be a down payment on what you have.
If I could figure out a way to be comfortable, and utilize it while gone I'd consider it.
Any idea from Mike Poor would be greatly appriecated
Thanks

hey 1914, 60k is quite a bit more than i put down. my old crane sold for around 55k without bed & dump hoist. you might check around for a demonstrator model knuckleboom. mark chisholm is right though, it would be easier to find like 20-30 ton stiff boom (used but not abused!) this might be better since your only here 3mos. yr. personally i wouldn't want anyone else running my rig. i've heard too many stories about big shock loads w/ no visible damage.... then 2weeks later have major structural failure of some kind. i bought my crane out of necessity (too many lg. hazard rmvs.) but also for my love of trees and working in them. so for it to work out i end up working in the snow or like last week in the rain etc. would it work out for you to rent? when you figure crane maint., payments, fuel, lic. plates, parking/storage, etc. 3mos. rent might look pretty good. it's all tax deductable and alot fewer headaches!

Thanks again for the responce Mark and Mike,
120' would be great. Right now I use 3/4" plywood on ground to drive over and don't feel I've insulted the ground to bad. Could I still drive on residential driveways ect...
Where do I check for a demonstrator model?
Major structural failure doesn't appeal to me!
Do you think I could find a sound 120' for sixty?
I love trees also.
And belive it or not people also.
thanks much for your help

Greetings Mark,
Thanks for the sight. If I can ever do a favor for you sometime let me know.
There is no Hockey in Ecuador. My thirteen year old made bloody chicolets out of his front teeth in Wisconsin from Hockey so not having it isn't all that bad.
There still is "Dodge City" with Marshal Dillon and all down there.
You, Mike, and Tom D. have really been a great help.
Thanks again.
Am still looKing for the knuckelboom demo.
