The triple crusher cannon is a weapon from the Generation One continuity family.

On the rare occasions when Nautilator isn't lost or slowly rusting to death, he carries a triple crusher cannon into battle. This weapon (which sounds too cool to belong to Nautilator, really) generates bands of energon, which wrap around a target and tighten until it's been crushed into scrap. When combined with Nautilator in Targetmaster mode, it somehow becomes a torpedo cannon.
