When US company Canyon Rock in North California, acquired a second quarry this year, the business found it required a primary crusher that would be able to handle heavy duty quarrying applications easily. The solution was provided in the form of a Sandvik Construction UJ440i tracked jaw crusher. In 2014 Canyon Rock acquired its second quarry. This provided material for rip rap, and stone, for the Sonoma-Marin Area Rail Transit project - a 70 mile (113 km) rail and bikeway which crosses the region. The family owned company's reputation for operating with optimal efficiency was at stake, so it was essential the business chose the right primary crusher - one that could handle heavy duty quarrying applications easily. Canyon Rock co-owner Jonathan Trappe said, "The UJ440i is a step-up. The chassis, the frame, the belt - everything is sturdier. We were looking for something that would last a lot longer than a regular contractor's primary jaw, something that would run well and last for 15-20 years."
