circuit to provide strong push/pull force?

  1. 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.
