hey jazak the phone # is: 330 916 6461 ask for tim or udo. if your on the west coast try 916 996 3503 ask for patrick. these cranes are really handy for our application. some of the advantages over standard cranes are: power to weight to reach ratio, manueverability, more control (when used without the optional winch), you can work with boom completely horizontal, etc., etc. i've got a pin on man basket which transforms the thing into a bucket trk. with 100 feet of side reach, 3 elbows, 12 extensions. so it not only can get you up the tree, but lifts out huge chunks and then hauls them too! it's just like every other piece of equip. though, if you abuse it (overload it etc.) something is going to break or someone is going to get hurt!!!
