I have to say I'm really impressed with how some of the European companies are adapting miniexes for taller building demo; using them to bring tight structures down from the inside out, one floor at a time (kinda like we used to in the old days with sledges and wheel barrows).

That is a great question. I don’t know if we have lost touch in a sense. It is just the way things and technology is going. With buildings getting built closer and closer together, the industry has to come up with new ways to combat these things.

I think some of it is that XYZ Company has one so now for me to compete I need one also. I have only seen a couple of projects that used them and they were effective, but I think that was mainly the operator. Like demobud I have seen them used on a couple of projects and thought what the heck are they doing.

Just to play devils advocate I suppose you could say that the technology creates a new skillset that must be learned. That being said, I see where you are coming from; I guess it has a lot to do with a company's bottom line. I know I can't afford one so I tend to stick to what I can reach, so to speak. I have used high reach equipmenet in the past and am ambivalent. I have seen them used correctly and seen them used where they were absolutely unecessary.

I have seen many high reach excavators. For the life of me I can't see the cost justification versus the dependabilty and usage. I saw 1 that crashed like a computer, 1 that had a rotating shear that was being fixed more than used and 1 that took an Einstien to get the proper angle because the rotation would free swing.
I've wrecked 2-8 story buildings with a 400 Komatsu and a bucket, both in Hospital environs. I demo'd a 9-story hotel the same way. Are we losing touch with true demolition techniques? Does this loss justify the high $$$$ for high reach vs. crane?
