#Man saver post pounder driver

Hydro is usually much more expensive than equivalent pneumatic, but the power source can be a lot cheaper. We have hydro or pneumatic post drivers, I run hydro tools off my buggy power steering, and I'm a big fan of hydro tools, but pneumatic is a lot more popular in the US. The other, the Rhino, I'm not very familiar with, but it looks like it's more competitive with what I work on (the link ultimately goes back to Crowder Supply, one of our dealers I work for Atlas Copco).

It looks inexpensive and effective, but slow.

So I just clicked the links, the Rohrer driver you linked, it looks like the body is the piston.

Extrapolate from that what you could do if you could swing a 30 pound sledge, or a 60 pound sledge. As a general concept, you can think of the pound rating relative to a sledgehammer, you can swing a 5 pound sledge. A post driver will probably be in the 30-60 pound range, a jackhammer might be up to 90 pounds. These are typically rated in pounds, which is an industry standard, but it's hard to precisely measure, similar to horsepower. So the tool itself doesn't jump up and down, it more just vibrates, as the piston runs up and down, transferring its momentum into the driven post, driving it into the ground. In a jackhammer, the anvil is right sitting on, or is itself, the chisel or point. It retracts (up), then runs down at speed, smacking into the anvil, which in a post driver, is sitting on top of the post you want to drive. So no harm as long as I stay out of it with the yellow star police (reminder: I can't sell anything, can't get you a deal on anything, can't even quote you a price, I'm in support, not sales).Īnyway, the air and hydro tools work basically the same way, the power supply fluid is used to move a piston up and down in the housing of the tool. If you call me at work I'll explain this same stuff without verifying who you are, no amazing trade secrets.

I don't mind posting stuff here, I'm in tech support, specifically on air compressors, but I play with pneumatic and hydraulic tools a fair bit.
