This is old fashioned... There are now telescopic grippers without a chainsaw in the bottom. Instead there is a hydraulic cutter blade that sheers off any tree trunk upto 14 inches in diameter with a 16 inch semi circular knife.
I would think that it could be far too easy with this machine to cut off more weight than it could control at extended reaches. With a regular modern crane, the weight can be known or tested before actually taking control and a decision can be made about the lift. This seems to have the potential to be left holding an unknown weight with no plan B if that weight is found to be too much.
This is where experience and common sense kicks in... You could get in serious trouble with heavy equipment, if you don't know what your machine is capable of...
@@oldretireddude For sure, but that's sort of true with all power equipment. They all carry huge danger because they create a false sense of power. I'll even notice this sometimes with my battery powered drill. I'll get so used to easily drilling in screws that on occasion when the screw hits something solid it can't go through my limp wrist will be twisted by the torque of the drill lol. User error of course. I imagine these larger machines carry some kind of license and permit to operate. I wonder if the boom itself can detect how much tension is being put on it and if that information is revealed to the operator in the cab.
Think these wheeled sennebogens are great at roadside tree removal, but not so great off road.
Agreed.

Probably why when doing tall tree's the operator is taking it down in smaller chunks.
@@heckyes Agreed, but if you guess wrong, all you can do is let go and hope.

@@heckyes There are strain gauges all over the machine and booms. Plus an accelerometer on the counter weight to detect tipping and rocking.
who need a chainsaw buy a 817E tree handler
