circuit to provide strong push/pull force?

I'm looking to build a device that will need to exert a fairly significant
pushing and pulling force- it will need to pull up the hasp of a
combination lock(once it's unlocked). I've seen schematics online for a
device that uses some massive solenoids- does anyone know of a more
compact way to deliver a large force using a circuit? If solenoids are the
only way to go, recommendations would be appreciated. I'm not sure how
much push force I need yet, i'll need to hang weights on the lock hasp to
find out. Are there any reasons for getting just one push/pull solenoid
vs. two push or two pull solenoids? thanks for any advice.

How about a low speed gear motor with an arm on the output gear? The gear motor
can provide appreciable torque.

A small motor turning a threaded rod through a nut?

What's that Lassie? You say that ben bitdiddle fell down the old
sci.electronics.basics mine and will die if we don't mount a rescue by
