Auxiliary machinery saves lives. Submarines, tanks, elevators, construction equipment and other large industrial machines come equipped with auxiliary machinery in case a part of the machine breaks or fails. Auxiliary machinery is the last line of defense.

Backup Plan

Auxiliary machinery operates only after primary machinery fails. For example, submarines often feature two engines. If the primary engine fails, the auxiliary engine begins to operate. The second engine is a type of auxiliary machinery. The auxiliary machinery is a kind of backup plan.

Use

Auxiliary machinery can be very expensive and it takes up space. Small, cheap or unimportant machinery like a can opener does not come equipped with auxiliary machinery. Auxiliary machinery is usually only present if machinery malfunction would cost lives or a great deal of money.

 

Variations

Auxiliary machinery comes in many shapes and sizes. Not all auxiliary machinery is large and heavy like submarine engines. The Navy outfits all ships and submarines with auxiliary refrigeration machinery. This auxiliary machinery keeps engines and food cold in the event that the primary cooling machinery breaks down.
