if you're terribly afraid about a buildcraft device exploding while powering a QUARRY...then just use a cluster of redstone engines wired up through some conductive pipes. It takes, what, 15 of them in all to max the quarry speed?

you can always go to creative/nei and spawn yourself the stuff to test the setup.
