In 1973, John Bruce, founder of Rock Systems, Inc., saw the long-term potential for a business catering to customers who needed a source for well-engineered equipment for handling raw materials, “The Crust of the Earth.” Our customers now include not only those who process rock, sand and gravel from commercially permitted material sources, but also contractors at construction sites who produce specific needs products, such as rip-rap, or process recycle materials, as well as contractors who simply need to move material as quickly, economically, and safely as possible.
