Tight machining tolerances of the housings, bearing brackets, and the conduit box provide the explosion-proof integrity required by international agencies. Cast iron conduit box parts along with packing glands and protective hose connectors meet the requirements of ATEX, IEC, MSHA and other certifying agencies. The motor line meets or exceeds global high efficiency standards, provides up to 1,100 volt capability, and offers optional features such as special shaft configurations, double shaft extensions and flange mounting configurations. www.abb.com for improved digging performance. Automatic SmartLoader Logic helps save fuel by automatically decreasing engine torque when the loader isn't working hard, such as when it is driving with an empty bucket. An electronically controlled HST drivetrain features the Komatsu Traction Control System, which enhances operation on soft or slippery ground. The machine is equipped with the exclusive Komatsu EMMS (Equipment Management Monitoring System), which provides enhanced diagnostic features that give the operator and technicians greater monitoring and troubleshooting capabilities. EMMS also continuously monitors all critical systems, as well as the planned maintenance schedule, and provides troubleshooting assistance to minimize diagnosis and repair time. www.komatsuamerica.com New Motor Management System Brings Higher Functionality Siemens' Industry Automation Division has expanded its Simocode Pro motor management system to include a basic unit with Profinet interface. Linking up Simocode Pro via Ethernet to higher-level automation systems allows new functions to be provided for motor diagnostics, control and protection. The additional integration of PROFIenergy Komatsu Loader is Tier 4i Certified Komatsu America's new WA320-7 wheel loader—replacing the WA320-6 and WA320PZ-6 models—is powered by a SAA6D107E-2 165-hp (123 kW) engine that is EPA Tier 4 Interim and EU Stage IIIB emission certified. Komatsu says the 33,731-lb (15,300-kg) loader features improved efficiency, lower fuel consumption, more operator comfort, and enhanced serviceability to maximize productivity while lowering operating costs. It uses the company's Parallel Z-bar (PZ) loader linkage to provide the benefits of parallel lifting for pallet moving and high tilt forces to handle large attachments. The PZ linkage also offers large break-out forces to make bucket filling easy and quick. Its lift force is increased by up to 10% compared with the WA320PZ-6 www.e-mj.com APRIL 2013 • E&MJ; 155
