Portable Expandable Bombing Cart

When you're 80 feet up on a spar chunking down wood, how big a target pad below you can you reliably hit with each chunk? 10x10, 20x20?

How deep would an airbag wood catching platform need to be to catch a plummeting 300 lb log? 6 feet, 10 feet?

I know I can hit an open trash can with palm fruit pretty consistently from fifty feet up.

I think I could reliably nail a 6x6 foot airbag trailer from 80 feet with 3 foot sections.

I see a towable expandable airbag cart with its own built in air compressor as a handy enough removal aid to warrant building a prototype. It would need to be able to sit down off its axles and distribute its weight out to its perimeter. Dimensions roughly equivalent to an airbag in a standard pickup truck bed, once expanded.

The idea has probably floated through every removal climber's mind at some point, but SoftBankHawk's thread bout his challenging job in Japan has churned the idea up in my over active imagination again.

The next logical step is to anchor a speedline to it so you can nail it reliably from a fair lateral distance.

Brilliant! This would also be a good tool for dropping spars over fragile terrain like driveways. Inflate two small air bags under spar once dropped, then deflate large air bag remove and start cutting.

Gymnasts, divers and pole vaulters use various crash pads to practice dismounts.

Rather than inflatable why not make a big onion sack and fill it with chunks of old foam from beds and sofas? cheap but if it gets wet there are other things to deal with.
 
I suspect a single fan and generator, along with a 12x12 foot vented airbag would all fold up and fit into a trailer capable of fitting through a 3 foot gate.

Much like a children's jump house when deflated.

Made rugged enough it should catch logs up to 300 lbs with no problem.

The bag has to be vented in order to absorb the logs velocity, rather than bounce it.

It should work great on any level surface.

Jomoco - That looks like a much better idea - Throw a heavy duty canvas cover or two over it to help protect the bag itself and you're off to the racaes!
 
I actually have a drawing of this thing somewhere. I designed it about 7 yrs ago, just never did anything with it. My idea was to have the top made of woven kevlar for bullet proof durability. My air came from a backpack blower. Pretty expensive to build but it would be the bomb in many situations. Lots of uses. Sheilding glass doors when stump grinding was one I thought of.
 
One of my friends recently did a removal where they were butt hitching big walnut logs and letting them run to the ground and hit a hot tub cover that was on a patio. He said that worked really well. The diameter was too large to butt hitch and hold the pieces off the ground so the rope was basically to controll the piece when it hit the ground.

The air bag idea would be nice because it would hold the piece somewhat and keep it from bouncing around.
 
didn't Foamboy here try this kind of thing a few years back?

Foamboy found away of absorbing the impact energy of sections of palm trees near swimming pools from what I remember. Someone here must have pics or a link to vid Foamboy made which displays his cunning plan to change the face of urban treecare.
