hey mark chisholm, effer's owner retired last year and sold the co. but it's still going strong: they have new models and i've been getting my parts o.k. hey mr. ed, to answer your question about pros & cons of articulating cranes to stiffboom cranes: i researched this for yrs. before i bought my 1st radio control crane eight yrs. ago. and again with experience when i bought my new crane 3yrs. ago. i found knucklebooms "won" in every situation you come across in arboriculture (and general tree mangling) if you have a fly jib (they have an optional jib winch but i've never really needed one) some big advantages of knucklebooms are unfolding in tight areas, boom angle (horozontal= no prob.), side reach, work radius any angle, work across, in under, over, or through obstacles. with 3 elbows & 12 extensions you can manuever through canopy like nothing you've ever seen, no counter wght. safety is equal. no boom in the way of dump box, power to weight to reach ratio! etc. etc. cost and parts availability is a con. initial cost too! either type could break or flip if you push the limits!!!

err......parts?

hey mangoes, how've you been? in response to you saying err...parts, yeah these things are far from maintenance free! but mostly things like: high pressure filters, o-rings, the steel pipes that run along the jib cyls. etc. here's a platanus from today. it had been topped yrs. ago and had the deck built around it. it also overhung the secondaries in the back.

One Comment, Our normal crane service here is smith crane we call him skippy. The man has a 1975 tele crane no computer remote or anything. He feels the way the crane reacts, with the remote in the tree you can't feel it. you dont know if your pushing to hard.
By the way me and skip have been on some hairy jobs toghether, some only radios as communication not sight. He has never hit or have come close to knocking me outta a tree. Great guy to have behind the controls.

My crane is a 1979. I to can feel alot but the load charts are important. When picking loads from height the feel method doesnt help unless you can set the load back down(if it is too heavy. The planning is more important.Although I dont have a remote I know I can direct the tip of the crane better from the atree than on the ground quite often because I dont have obtacles or sun in the way.

When doing tree work with cranes its better to act instead of reacting as allmark has said.
The remote on a crane like that should have a overload protection system, and a LMI system aint too hard to incorparate into the remote.
Knot to mention the feel method doesnt give you feedback to know if your 1k over or under what the chart says. After enough time twiggling the controls on the remote the operator can adapt the similar feeling for eyeing the boom, deflection and how the chassis is reacting.
The best option (IMO) is to have and use an LMI system. Eyeballing the weight of wood that your picking can be done with reasonable accuracy, I have had one pick that the LMI said was off by more than 10% of the weight. On that pick he reported a weight of 3750lbs when I though 2500lbs. However the LMI was caught up in a neighboring tree back at the crane (just realizing this now) so the LMI was off by 10' of radius (135' indicated 125' actual).

hey demo, i appreciate your coment about running the crane on feel. but if you use slings that don't stretch then all you have to do is make the sling taut. any more tension than taut is too much and YOU WILL FEEL IT IN THE TREE! i can also see the tension on the boom from the tree. like allmark said without careful use of a loadchart and log wght. calculation, you'll be in trouble. my remote has a load sensing system similar to an lmi that lumberjack mentioned. it lets me know when i'm at 90% and automatically switches to (F.P.I.) mode. this slows hyd. flow and allows the crane to lift about 20% percent more. unfortunately tree dismantle is the hardest application for crane use. there isn't much crane engineers can do to protect against a massive overload! the thing is going to flip or break! but demo i tip my forestry helmet to guys like skippy (and all good oprtrs.) who can keep a climber comfortable in the tree. i'm sure he does great but i wouldn't want everybody running on feel.

Hello Michael Poor,
I have been reading all of the information regarding your sucess with the Effer model 550 with jib.
You are a real testament to the Effer brand. As a factory rep for Effer, and an old tree man myself from California ( now Washington State) I can apprecaite the diffuculty removing trees where ther is no "drop zone" underneath. Keep up the good work.

Yes, the machine will let you know when you reach 90% of the load chart by beeping, no restrictions yet. When you reach 100% it is another type of beep, and you must retract the load or let it down, for safety purposes.
The Effer machine is the best solution whe you want to lift and haul on the same truck.

Remotes sound cool , When they make a remote controlled groundman let me know . A white one with a turbo option. with an open close on the lips.

local forest preserve had this q. alba uproot and fall into another. held up only by a 4" limb, it was over a house bordering the woods. (you think the homowner was a little nervous!) i had to brush it out 1st (tied to the other oak of course) once the 46'log was within load chart, i was able to crane out.

I have one question, why cut it at 4'? Why not cut it at the ground and load it long? Did it have to be cut at that height for the client?

Trying to shave some weight maybe? That is one hell of a big toothpick at that reach. Very impressed. Does the crane have scales? and how close were you on your guess for weight?
