| WA380-7 wheel loader  Komatsu America introduced the WA380-7 wheel loader. With a net horsepower of 142 kW, the WA380-7 is powered by a Komatsu SAA6D107E-2 engine and is EPA Tier 4 Interim and EU Stage 3B emission certified. Built upon a proven Tier 3 engine platform, Komatsu has leveraged its leadership in technology and innovation to design an environmentally friendly engine that increases power while decreasing fuel consumption by approximately 10 percent, compared to the WA380-6. Weighing in at 18,100 kg, the WA380-7 features improved efficiency, lower fuel consumption, improved operator comfort, and enhanced serviceability to maximize productivity while lowering operating costs.The WA380-7 is equipped with the latest KOMTRAX technology, which sends machine operating information to a secure website utilizing wireless technology. Data such as operating hours, fuel consumption, location, cautions and maintenance alerts are relayed to the web application for analysis. The KOMTRAX fleet monitoring system increases machine availability, reduces the risk of machine theft, allows for remote diagnosis by the distributor, and provides a wealth of other information to drive business efficiency and productivity. New features of the WA380-7 include: • EPA Tier 4 Interim and EU Stage 3B Emission Certified Engine Built upon proven Tier 3 technology, the SAA6D107-2 engine provides lower emissions while also lowering fuel consumption. The Komatsu Tier 4 Interim engine uses an advanced electronic control system to manage air flow rate, fuel injection, combustion parameters and aftertreatment functions to optimize performance, reduce emissions, reduce fuel consumption and provide advanced diagnostic capability. Komatsu has also developed a hydraulically actuated Komatsu Variable Geometry Turbocharger (KVGT) and an Exhaust Gas Recirculation (EGR) valve, resulting in better precision and air management as well as longer component life. The Komatsu Diesel Particulate Filter (KDPF) has an integrated design that will not interfere with daily operation but will keep the operator aware of its status. The WA380-7 also features Komatsu SmartLoader Logic, which provides optimal engine torque for the job required. Komatsu SmartLoader Logic helps to save fuel by automatically decreasing engine torque when the loader isn't working hard, such as when it is driving with an empty bucket. Komatsu SmartLoader Logic functions automatically and doesn't interfere with operation, saving fuel without decreasing production. • Large Capacity Torque Converter with Lock-Up The WA380-7 has a newly designed Komatsu Large Capacity Torque Converter with Lock-Up as a standard feature. This provides improved acceleration, improved hill climb ability, a higher top speed and lower fuel consumption. The Lock-Up function activates in 2nd, 3rd and 4th gears and gives the machine a maximum ground speed of 40 kph. The wheel loader has greater productivity in V-cycle applications because of the increased tractive effort. The improved hill climbing ability allows the WA380-7 to up-shift gears faster because of improved acceleration. The wheel loader can also achieve higher gear ranges and maintain higher ground speeds when working in load-and-carry applications. In most applications, production is increased and fuel consumption reduced, resulting in improved fuel efficiency (tons/gal). • Enhanced Operator Environment The new cab provides a comfortable and quiet work environment so operators can maximize their productivity. The front glass has been lowered and the dashboard has been redesigned to improve visibility. Electronic Pilot Control (EPC) levers and an F-N-R switch are part of a redesigned seat-mounted right hand console. An auxiliary input has also been added to connect an MP3 player or other device along with two 12-volt ports that have been incorporated into the cab. A new high resolution 7" LCD monitor features enhanced capabilities and displays information in 25 languages for global support. Using the monitor, the operator can easily modify settings for items such as the Auto Idle Shutdown or the auto-reversing fan. Operators can also check operational records, such as working hours or fuel consumption; monitor the KDPF; or check how much time is required before the next maintenance interval. The monitor also offers the operator the option of using the ECO Guidance function, which will provide operational tips to reduce fuel consumption. A separate high-resolution back-up camera is standard with every machine and is mounted on the right hand side of the console for operator convenience. • Convenient Maintenance and Serviceability The WA380-7 provides easy service access in order to reduce costly downtime. The new model has increased cooling capacity, wider cooling fin spacing and a standard auto-reversing fan to help keep the radiator clean. The machine is equipped with the exclusive Komatsu EMMS (Equipment Management Monitoring System), which has enhanced diagnostic features that give the operator and technicians greater monitoring and troubleshooting capabilities. EMMS also continuously monitors all critical systems, preventative maintenance, and provides troubleshooting assistance to minimize diagnosis and repair time. write your comments about the article :: © 2011 Construction News :: home page |
