Because Of This Jack

Did you even see a house being moved?  I have seen houses moved on trucks, but have wondered how they lift them off their foundations.  That is where I learned about screw jacks.  Screw Jacks are basically meant to lift heavy objects, such as houses. large machinery and vehicles.  Also I learned that you can by screw jacks online.  Can you think of industries that may use jack screws?  I was thinking that shipyards would have a need for them.  Screw Jacks can support very heavy weights, so I would feel perfectly safe walking under any thing properly supported by a screw jack.
