Re: TCI\'s Effer 655 Knuckle Boom
The main reason we couldn't go BIG is the wind. A thunderstorm rolled through right before we started the job, it brought high winds. So, instead of shutting it down we went smaller on some picks. It was basically 5 trees grown together. We filled the whole landing almost every time.
Q1. what were you good for at that distance?
At that distance I am good for around 4000 lbs. Its when I get to the LZ that it changes. I can't set the picks down like a crane with a cable can. I have to go horizontal to set them down. So, what I can pick in the tree has to work when I lay it on the ground. BIG would work if I was just holding in the air and never going to take it to the LZ.
Q2. did you utilize the log truck to feed the chipper or do you bring all debris back to the shop for some tub grinding?
We don't use chippers. We haul the brush and wood in same truck. We have pup trailers that go with the grapples. Everything goes to the shop for tub grinding.
Q3. why no rope bag for the climber?
He has one. He stayed in the tree most of the time and didn't really run into a problem. I personally always use a rope bag. That was not me in the tree.
Q4. what was the most amount of slings used on any given pick of that tree, most i saw on a 1200 or so pound branch was 3 so i was just curious.
We mainly use one sling, we use two slings a lot and if we feel the need to throw a third one on we do. We did three on some. Due to the wind, we had to rotate the picks over a structure in order to get it to the LZ, so had to keep the load low and steady and the third leg worked great.
Q5. about how long per se does the average pick take from climber contact of the ball to untying of the last sling by the ground guy on that particular setup?
We don't have an average. It takes about 30 seconds to untie 3 spider legs on the ground by two ground guys and about 10 to 15 seconds to stuff em' back in the bag.
