Working from a Manbasket

Interesting that they are making you use the manbasket. Perhaps you should show them this:

Is the lack of respone on this thread because no one's used a manbasket doing tree work?
Anyone?

That would be my guess.
See this article about tieing in to the crane:

beginning on p. 43. This will eventually be put in the Articles section here on TBzz.

I dont see any problem with a man basket.They need to be used as they are designed for. Not near wires. I prefer a radio remote control so it can be operated from the basket. The link from TMW only shows the company did not have equipment in proper working order...not that it was wrong to do as long as the Z and crane manual is followed.
Are you referring to a man basket attatched to the boom or the load line. This would make a difference as to the efficiency of it?

Recently I did a job from a man basket off a 50 ton crane with the jib fully extended. It had been many years since I was in one. I found it difficult and frustrating. The job was conversion of a big hemlock to a snag to make a work site safer for another crane lift.
I finally had to lanyard the basket to the tree for some cuts because when I pushed the basket would move. This did not feel safe.
The crane company that we were working with won't allow work off the hook or a boom tie in.

I've never had anyone insist I work from a man basket. And I wouldn't. Its easy to come off the hook if the cage rests on the tree at all and the chains go slack. Tieing in off a rope and sit harness/bosuns is safer, and more ergonomic when it comes to handling heavy equipment like chains and chainsaws. Also, as maybe Scott was saying, using a pushing chain (top side of saw bar) of a chainsaw pushes you away from the work.
The only reason I can see for it is preventing a crush injury. But I've never had a crane driver swing me like a wrecking ball.
Man baskets are not part of my risk assessment controls when it comes to generl tree work with cranes. There are safer options that general health and safety inspectors don't always appreciate.

If the crane has the proper safety on the hook this shouldnt be the case (apin on the latch). I would not insist on a man basket as an employer but it could be useful at times. What about one attatched directly to the boom? It wouldnt shift as you cut.

Attachments
As Scott mentioned the basket moves alot. Hadn't thought about lanyarding into the tree to minimize movement. the possibility of taglines were mentioned but not employed.
Allmark, there was no possibility of attachment to the boom. There was 197' of boom to the work area and too many obstacles to work the boom low.
As Laz mentioned, there is concern for the basket attachment. There was no means to lock/pin the latch, a clear OSHA violation.

Heres a good article that takes you thru some of the basics.

When working from a load line attatched platform you could still tie in with a climbing system attatched to a friction saver/shackle set up like normal crane removals. This would provide decent in emergency situations and act as a safety if the basket became detatched from the hook.

You should use Western Crane Inc. if you haven't already. They have some real good operators.

Mikes looks great - similar to a bucket truck/MEWP. I prefer hanging from a crane as a false TIP rather than have all the restriction of a MEWP. Plus I don't have to worry about damaging a truck/outrigger (because they are usually well out of the drop zone). If the tree is unstable and does actually collapse, it won't take the boom with it. Then you can use the crane to shift everything road side after.
The hooks we have over here, are just a hinged latch. These are often stiff or too easy to open.

I've only been in a manbasket on one job and personally enjoyed it quite a bit. Basically I was using it as an elevator and not working out of it. I was taking down five 100 foot Douglas Fir logs that had already been stripped out. We were using a 85 ton crane. I would get in the basket and he would pull me all the way to the top at full speed, swing me over to the log and I would tie in and then step out. I was up there so fast I thought I was going to be sick a few times. The crane company has a policy of no tying into the hook so that was my only option if I didn't want to spur up those huge logs.

It's funny that this subject came up today. I haven't used mine for 2 weeks. Then today, I used it all day pruning trees at university of IL research sites. I just use mine to convert my crane into a "bucket truck" The manuverablity with a lg. knuckleboom w/ man basket is unbelieveable. Mine pins to either side of the boom w/ 2 lg pins. Don't forget to wrap a boom strap w/ "d" ring around to clip into! Lumberjack had a cool post where he used one crane w/ 2 winches! (one line held the basket & the other line held picks!)
