Strange looking boom. I ran a 1066, saw a 1266 in Trenton Mich once. But that 1466 looks like they had it all made up for the extreme length for sure.The 1266 boom was so heavy, the bucket was downsized as to get any cycle time on deep digs. We had a 3500 Insley that had a main boom with a standard stick that they had some company make a long stick out of it. 11 foot was added to a 15 foot original stick. Made the machine freaky looking and the bucket was really downsized to even get it out of a cut. I've never see a stick and boom like that 1466. The only thing that I have ever seen close to that is a Priestman. They have one here in South East Michigan that has 75 feet of reach with a 1 yard bucket. The stick has a cable winch like a drag line that gives it super power in the muck.
