The hydraulic excavator mount: for when you absolutely, positively have to break big s%$# into little s%$#.  Sometimes we run across a tool and just have to write about it, regardless of practicality, and this one hits all the high points:  Noise — check.  Big — check.  Earth-shattering (literally) power — check.  This is a 12” auger that mounts to an excavator and drills into solid rock.  Sweet! 

These are actually used to split and drill boulders and sides of mountains. HEM’s can be found on large contruction projects and highway construction sites — we even saw a few clearing out rubble in the subways of New York for the new tunnel. 

They require a boom lift capacity of 3,000 LBS with a hydraulic flow minimum 40 GPM @ 2250 PSI, and they must be mounted to an excavator that’s around 20 – 25 tons.  If that doesn’t get you going we don’t know if anything will.

I wonder how fast you could destroy a car with one?

    Pretty sweet! On the subject of hydraulic-driven stuff you do with end loaders, folks reading this post might be fascinated by the subject of “helical pier foundations”, a construction technique that’s finding its niche in tricky building sites.

    Picture the foot-or-larger earth auger used to excavate a big post hole. Now imagine screwing it into the ground, not with the purpose of removing material from the hole, but of burying the auger. Run it down until the hydraulic motor stalls, adding extra sections of drive shaft to run it deeper if necessary. When you’re done, that thing is wedged pretty firmly into the ground. That’s a helical pier.

    Do that a dozen times in a rectangle, cut off all the shanks level with each other, and bolt beams to them. Build a structure atop the beams. Ta-daa! Helical pier foundation. No digging, no concrete pouring, and it works in sandy and muddy places where other techniques fail. Neat stuff.

    I’m sure there are downsides too, like “where do you go for a tornado?”, but I was fascinated by the technique when I read about it in the Journal of Light Construction a few years back. Looking at the HEM stuck on the machine up there reminded me of the drive technique used for HPFs, so I figured I’d post. (But then, the sky could be blue and I’d post about it.)
