Joy Mining Machinery finds happiness underground. The company manufactures and distributes underground mining equipment and bulk material conveyor systems from multiple service locations located near major mining regions throughout the world. The foundation for Joy Mining Machinery was laid when inventor Joseph F. Joy received a patent for his mechanical gathering arm loader in 1919. Products include bolting systems (used in coal mining), haulage systems, and longwall systems (consisting of shearers, roof supports, face conveyors, stageloaders, crushers, and mobile belt tail pieces). The company is a subsidiary of Joy Global. Sister company P&H Mining Equipment produces surface mining machinery.
