Abstract
A portable ice crusher assembly to be mounted on the bow of an icebreaker. The main sections are a deck support assembly, a deck power assembly and a front support assembly with a hanging container with weights within, and sharp pointed spikes at its bottom. The ice crusher assembly breaks up the ice in front of the icebreaker by dropping the container onto it. Instead of breaking the ice with a ship's hull an ice crusher assembly can be used.
