CONDITIONS OF BEST EXCAVATOR AND DX340LCA Conditions of “Best excavator”
KEY SUMMARY of DX340LCA
• Unlike commercial commercial cars, cars, excavators excavators exist to CREA CRE ATE PRO PROFIT FITS S, not to please consumers • To create more revenue revenue of customers, –1) MAXIMIZE PRODUCTIVITY by enhancing working speed & power with qualified E/G and hydraulic parts –2) MINIMIZE DOWNTIME by enhancing durability of core components
• YOUR “GOLDEN GOOSE” AND “PATHFINDER”
• To reduce costs costs of customers, customers,
• INDUSTR INDUSTRY’S Y’S BEST PRODUCTIVITY –Overwhelming –Overwhelming capacity capacity of Doosan in-house mechanical mechanical E/G
–1) Not only provide provide reasonable reasonable complete complete machine price –2) but also provide provide BETTER FUEL EFFICIENCY & MAINTENANCE COSTS • Besides profits, profits, good excavators excavators provide provide BEST COMFORTS & CONVENIENCE of operation and maintenance
–Based on market-prove market-proven n productiv productivity ity (profitability (profitability)) of S340LC, enhanced durability to endure any severe working conditions `
–Industry’s –Industry’s best best machine machine power power / forces forces & Massive bucket • MINIMUM DOWNTIME –Much improved improved durability of front and undercarria undercarriage ge by adopting new-generation technologies & components • IMPROVED FUEL EFFICIENCY & BEST COMFORTS –5.5% improved improved fuel consumption consumption than previous previous model model –Top-tier –Top-tier level cabin cabin comforts comforts & operational operational convenience convenience 3
DIFFERENT APPROACH OF DOOSAN AND OTHER COMPANIES Product platform strategy

Why Mechanical Engine for Emerging Market Mechanical Engine and Electronic Engine Mechanical Principle controlled with a Mechanical system Merit
Demerit
Less trouble and can be corrected easily. Engine and parts prices are lower. Not environmentally friendly
Electronic controlled with an electronic system Environmentallyfriendly engine. (Meets EU Tier-3 Regulation) Engine and parts are expensive
• –Electronic – Electronic E/G has better performance and higher efficiency. (x)
• THE FACT –Electronic – Electronic E/G was developed to meet environmental regulations in developed countries such as EU, NA, not for *AP/E region –In – In emerging markets, mechanical E/G is more favorable in many ways –Most – Most of manufacturers use electronic E/G in their products for their production convenience, which makes the customers pay higher prices and costs. *AP/E: Asia Pacific and Emerging market

KEY SUMMARY of Doosan’s Mecha Mechanical nical Engine
• MORE RELIABLE THAN ELECTRONIC ENGINE –Inferior quality fuel can damage the injection injection system severely severely because electronic E/G is highly sensitive to dust & moisture • LOWER PARTS COST THAN ELECTRONIC ENGINE –Doosan’s injectors generally generally do not malfunction, malfunction, but competitors’ often break down(cost $2,000~3,000) –Electronic E/G uses hi h efficienc efficienc filters which are ex ensive –Electronic E/G needs needs electronic electronic controllers, controllers, as as well as many ` sensors and wire harness • EASY MAINTENANCE –Simple structures structures and with with fewer parts at lower lower prices, making troubleshooting much easier –Many mechanical mechanical E/G specialists available available
“It is difficult diffic ult to diagnose problems in electronic engines and harder to repair if spare parts are not available.”
