EQUIPMENT GALLERY tube component, also has been eliminated in the DH500 shank concept. An innovative design reduces the num- ber of hammer components, thus reducing the amount of component wear points, making hammer service simpler and less expensive. Lead threads on the top sub and driver sub ensure easy coupling and uncoupling of the hammer. www.rockmore-intl.com Mining Valve Selection Guide Red Valve designed its first pinch valve for the mining industry in 1953, and in the fol- lowing decades, has built on that heritage by producing various types of valves to han- dle many of the tough applications in the mining industry. The company's recently released, full-color Valve Selection Guide for the Mining Industry highlights Red Valve's extensive product offering, including control pinch valves, slurry knife gate valves and Tideflex air diffusers. The brochure includes application photos of installations ranging from South American copper mines to Midwestern U.S. taconite mines. www.redvalve.com October 2012, and an intrinsically safe ver- sion approved for use in coal mines is also in the product pipeline. www.nltinc.com Snubber Reduces Stress on Shovel Dipper Parts L&H; Industrial, located in Wyoming, USA, has designed a hydraulic snubber that the company claims improves mining shovel dipper performance by enabling smooth opening and closing of the dipper door. This system, according to the vendor, has been proven to reduce maintenance costs for the dipper, dipper door and even for haul trucks. Tests have shown cracking to be drastically reduced in the dipper and dipper door because the door is hydrauli- cally closed rather than slammed by weight and gravity. Less damage to haul trucks is incurred because the door does not slam against the side of the bed when opening. Due to the smooth closing action, the dip- per latch bar and dutchman insert also benefit by providing longer service life. www.lnh.com Software Builds Geological Shapes from Drillhole Data MineSight Implicit Modeling (MSIM), soon to enter the market, will "revolutionize" the generation of geological surfaces and solids in a general mine planning system, accord- ing to software developer Mintec, which Miner Cap Lamp Works with Tracking Tags NLT recently introduced its second-genera- tion all-in-one mining cap lamp, the Genesis. The lamp's design includes the ability to integrate tracking tags while keep- ing the battery and light source in a single enclosure. Mine operators can choose from a number of standard RFID or Wi-Fi tags, powered by the cap lamp's high-capacity battery. Using the same contemporary design as NLT's Polaris lamp (shown here), the Genesis provides a light pattern that's consistent with all NLT lamps, providing a focused spot. The Genesis is currently being field-tested and will be available in www.e-mj.com SEPTEMBER 2012 • E&MJ; 167
