Here's a couple of less-conventional ways to do a crusher (excuse the fag packet scribbles, couldn't be bothered with Flash.
The first one, I think, is how katnip works. Each jaw works a bit like a bell crank (such as an accelerator linkage in a flat front van/truck). A single ram/linac moves one end of each jaw, such that each jaw pivots part way along its length. The main problem with this is that the initial force has to be a pulling force, rather than a pushing force, so it doesn't work well with most pneumatic cylinders, which tend to be less efficient used this way.
The second one is how the Belgian bot TAN works, basically, it's a pair of pliers, the force pushes the "handles" apart, pushing the business end closed.
Just food for thought...
