This new seal is suitable for water/ wastewater treatment, and provides an easy upgrade from the use of tradi- tional packing and component seals. Ure further stated that, "Through its slew of benefits such as low operating cost, contamination-free installation and water leakage savings, this seal will provide our customers the ability to bolster water conservation efforts and adhere to emissions regulations." www.johncrane.com Metso Introduces New Truck Body at bauma 2019 by carly leonida, european editor One of the more interesting product launches at the bauma 2019 trade- show in April was the Metso Truck Body (MTB). The company has pro- vided rubber liners for truck boxes for decades and, having listened to customer requests for a product that combined the durability of a rubber liner with the capacity and strength of a lightweight steel body, it decided to develop its own solution. "Hauling is one of the most cost-intensive components of a typ- ical mining or quarrying operation. In addition to fuel and labor, there's plenty of maintenance involved, too," said Lars Skoog, vice president of Mining Wear Lining and Screening, who led the MTB launch event. "To ensure cost efficiency, a haul truck should carry as much payload as possible on every round," he added. "At Metso, we set out to tackle this chal- lenge and designed a truck body that requires minimal maintenance while maximizing payload. The result is a lower operating cost per hauled ton." The MTB is currently available for off-highway trucks in the 100-plus- ton class, although Skoog said Metso will be looking to extend the range to smaller truck models in the future. The rubber that lines the tray ab- sorbs the energy created through material impacts, preventing it from reaching the frame and thus allowing a lightweight, high-strength steel struc- ture to be used, instead of a traditional steel frame. The benefits include up to six times more wear life compared to bodies fitted with a steel liner, half the noise and 97% less vibration. Skoog explained, "Many mines pre- fer lightweight truck bodies because they enable them to carry more pay- load. However, the problem with these traditional lightweight bodies is their lack of durability — they often have to be replaced in every one or two years, or repaired, which gets expensive. "The rubber lining and high-struc- tural strength steel frame [of the MTB] have been engineered in a seamless process, utilizing the best qualities of both materials."
