52 • ROCK products • November 2018 EQUIPMENT & TECHNOLOGY CRUSHING & BREAKING Okada breakers are designed to be the best match to the appropriate class of carrier. Nitrogen gas in the top of the piston provides a cushioning effect during the piston ascending stroke, minimizing vibration, which in turn reduces operator fatigue and wear and tear on the equipment. The square-shaped main body is cre- ated using a special alloy and subjected to advanced heat treatment processing, making the hammer body extremely durable. In addition, Okada hammers use fewer parts than competing brands of hydraulic breakers, so there is far less chance of problems developing. New special alloy steels and an advanced heat treatment system enhance main component durability. Medium and heavy class TOP series breakers are compatible with auto lube systems. By adding greasing points, both the shank bushing and front cap bushing are lubricated individually, resulting in longer service life. Stringent quality control and testing From material selection and machining to hardening and final assembly, every step of production is controlled by an exhaustive quality control system. To ensure the absolute best quality possible, each unit is fully tested in a specially equipped room dedicated to performance inspection. Okada America, Metso Launches a More Efficient Lokotrack LT200HP The Metso Lokotrack LT200HP mobile cone crushing plant is designed for secondary and tertiary crushing oper- ations, such as producing aggregates for railway ballast, road construction, asphalt, and concrete fractions. Thanks to its direct v-belt drive from the gearbox, the renewed solution delivers fuel consumption savings of at least 15 percent compared to hydrau- lic-driven cone crushers. Furthermore, the LT200HP complies with European Stage V emission regulations. "Fuel consumption and efficiency are always at the top of our customers' priority lists, and reducing emissions levels has become an increasingly important issue in recent years," said Kimmo Anttila, vice president, Lokotrack Solutions, Metso. "In this respect, the LT200HP delivers on all counts with a fuel consumption savings of 15 percent or more." In addition to being more efficient, the renewed LT200HP also features several safety and maintenance improvements. These include elevated service plat- forms to ensure safe, easy access to service and maintenance points, and improvements that make daily mainte- nance quicker and easier. The LT200HP is also available with the Metso ICr wireless information and con- trol system, which allows customers to monitor and control the crushing plant from an excavator cabin. The entire line of Metso primary Lokotrack plants or Metso mobile screens can be controlled with Metso ICr for a complete crushing and screening solution. "The compact transportation dimen- sions of the Lokotrack LT200HP combined with its powerful Nordberg HP200 cone crusher make it a win- ning solution for mobile crushing and screening," Product Manager Jouni Hulttinen concluded. Metso, New Stedman VSI Anvil Ring Design Stedman offers an externally adjustable and visually indi- cated anvil ring for Stedman vertical shaft impactors. The new, patent-pending VSI Anvil Ring is easily adjustable by an external threaded jack bolt. Anvil ring position is verified externally by an integral posi- tion indicator. Internal access to the crusher is not required for anvil ring adjustment, increasing safety and lessening downtime. Adjusting the anvil ring position up and down, allows for even wear, nearly doubling the life of the anvil ring in many cases. The anvil ring can be re-positioned with common hand tools in half the time previ- ously required. Stedman Machine Co., Okada Offers 12,000-15,000 Ft.-Lb. Class Hydraulic Breakers
