Rock Jaw?

[RNeumann]

Anyone used this thing or something like it for rocks? I'd assume I would take my bucket off so I could lift more.

Nice work! Do have the measurements for above and below the pivot point? That would be much appreciated.
I'm in a similar situation- lots of rock to move! Plus some of mine is down a steep hill and it would be impossible to lift it up with a grapple of forks.

If you will reply again tomorrow that will remind me to go out and measure them.

Luke - and as I remember you were able to move some pretty big rocks.

You can actually find pretty much all the measurements for the commercial one in it's patent: Patent US223986 - Apparatus for manipulating landscaping and other similar materials - Google Patents

I'm looking on my phone so it's a small screen but all I'm seeing is numbers-not dimensions.

Luke- this is a bump reminder

Ok. Posted the dimensions here :

Hope it helps.

Thank you! Looks like 9" above the pivot point and 28" below. I'm assuming the ratio is important but the scale can change?

No mathematics involved in my design. I actually doubt the ratio matters much as long as it is above a certain point (above the pivot is long enough). Longer just makes them harder to open while hanging.

Also the length of the chain connecting the sides should be as short as possible.

If I were making them to be put on laying on their side (rather than lifting straight up), I would have four legs rather than 3.
