Komatsu Introduces WA320-5 Wheel Loader with Hydrostatic Transmission

o Advanced Technology Hydrostatic Transmission increases power and performance o New cab layout and size for improved comfort o Easy maintenance VERNON HILLS, Ill.-December 1, 2003-Adding to its line of hydrostatically driven wheel loaders, Komatsu America Corp. (KAC) introduces the new WA320-5. Outfitted with Komatsu's electronically controlled Advanced Technology Hydrostatic Transmission (HST), the WA320-5 is designed to handle a wide variety of applications in government, utility, construction, sewer, waste and agricultural markets. This machine includes significant product improvements resulting in increased production, operator comfort, versatility and reliability. Powered by a turbocharged Komatsu SAA6D102E-2-A air-to-air aftercooled engine, the WA320-5 has a net output of 166 hp and fully complies with Tier II regulations. The WA320-5 reduces emissions, lowers fuel consumption by 15 percent and increases productivity, while lowering engine speed to 2,000 rpm. Increased Power and Performance The WA320-5 incorporates an electronically controlled HST with a Variable Shift Control System. The HST allocates only as much power as is needed for a given application, ensuring accurate and powerful operations. The variable shift control switch lets the operator set his maximum speed anywhere from 0 to 8.1 mph for a better match to hydraulic speed in applications such as tight v-cycle truck loading. The HST makes the WA320-5 a very powerful, efficient machine that responds quickly to varying conditions. Traction Control System The traction control system is designed to reduce tire slippage in certain applications where the loader may be working in sandy or wet conditions. Turning the traction control switch on automatically reduces tractive effort by 50 percent, thus reducing tire slippage. Hydraulic Braking System The fully-hydraulic braking system eliminates problems such as freezing and rusting caused by water condensation encountered in air-operated systems. Daily, time-consuming air tank draining is also eliminated. The wet disc service and parking brakes are fully sealed to lock out contaminants. Improved Operator Comfort The WA320-5's new, spacious operator's cab provides a comfortable work environment designed to maintain high operator productivity. The cab is five percent larger than previous models, which provides more leg room and storage space. The viscous damping mount system helps to minimize noise, shock and vibration in rough working conditions. The pressurized cab reduces noise levels to a low 70db (A) and keeps dust and other particles from the cab's interior. Additional features include new sloped entry steps and improved handrails, new doors and platforms for easy maneuvering in and out of the machine and a low effort, mono-lever PPC hydraulic system with a F/N/R control switch for smooth operation and easy usage. Serviceability Komatsu has designed the WA320-5 to include its Equipment Management Monitoring System (EMMS) that keeps the operator informed of 28 machine functions and helps prevent costly breakdowns and failures before they happen. Located behind the steering wheel in the operator's field of view, EMMS is just one of several new maintenance and service features on the WA320-5 that include: o Full side opening gull-wing engine doors for easy engine access o Improved drive shaft seals for extended greasing intervals o 500-hour oil and filter service intervals o Sealed DT connectors resistant to dust and corrosion o Fewer moving parts and service points About Komatsu Komatsu America Corp. (KAC) is the second-largest manufacturer and supplier of construction, mining and utility equipment and parts and services in North America.
