How about a stronger version of these...
I'm just catching up on some posts......
Before you instruct your next rescue class you may want to check your history.
The first use of single rope technique with prusik and mechanical rope ascenders can be traced back to the exploration of the Dent de Crolles cave system in 1934. American...
I'd tend to agree with SRTsteve860.
Although I'm no crane expert, this thread got me thinking.... and reading. You're right, there is not much info on this. Probably because they use adjustable legs or shortening hooks/clutches when rigging with chain to shorten the length.
You can't do/win them all :)
You have a good attitude. I'm sure that's reflected with you're dealings with you're customers. It should serve you well.(y)

It shouldn't have to cost ya to be a "nice guy", but unfortunately that is the way our society is going.
I checked out getting a patent once on an item I came up with (not tree related) and was told that that it would cost me around $5,000 to do so. I was also advised not to waste my money due to the small market and the expected profit that could be made off the item. Protecting your patent can be...

I like to see the phases as:
1: Leaving it where it falls.
2: Manually removing it by hand.
3: Moving it by cart/dolly.
4: Skidsteer or other motorized equipment.
5. Crane.
6. Helicoptor.
7. Laser/Phaser.

Yes it did. It had some hollow sections at the union and it was a little out of his comfort level. He came up with this idea.
I was doing a couple of other trees and had the camera with me.
Very nice Tom.
Bryan definately captures the "essance" of tree work and workers in his drawings. I believe his illustrations in the Sherrill catelogs were one of the main forces of their early success.
I had a local graphic artist, who is an excellet illustrator do some artwork for me. Its...
