DOOSAN'S NEW DX340LCA EXCAVATOR WITH ADVANCED SPECIFICATIONS

include an increased maximum bucket size of 2,35 m³, a side lifting capacity of 9,33 T at 6 m reach and 3 m height and a maximum digging force of 24,8 T. Traction has been improved with an 8% increased drawbar pull of 27 T. Advanced independent electronics has increased reliability of these machines and simplified maintenance procedures. Doosan uses high performance materials, combined with advanced computer assisted design techniques, including Finite Element Analysis (FEA) to improve design features of every new series. All materials and components are tested under the most extreme conditions. The shape of the boom has been re-designed for improved load distribution throughout the structure. For greater strength, material thickness has been increased to limit element fatigue, increase reliability and extend component life. A highly lubricated metal is used for the boom pivot to extend greasing intervals to 250 hours. Cast elements are used in the arm assembly and reinforcement is added around the bosses for additional strength and extended service life. High wear resistant materials are used for susceptible elements of the bucket, including the blades, teeth, rear and lateral reinforcement plates and corners of the bucket.

H eavy duty Doosan DX340LCA hy- draulic excavators, designed for efficient operation and high produc- tivity in demanding work environments, are gaining popularity locally in diverse sectors, including quarrying, mining and in heavy construction. “There are currently over 2 500 Doosan machines in operation locally and we expect to further consolidate Doosan’s market position and soon reach the 3 000 unit mark,” says Chris Whitehead, managing director, DISA Equipment, trading as Doosan Construction Equipment, part of the Capital Equipment Group (CEG) of Invicta Holdings Limited. “Doosan makes a substantial investment in an ongoing development programme to upgrade machines with advanced design features and high performance materials, for optimum productivity, reduced running costs and low emissions. “Users worldwide have the assurance that all Doosan machines offer efficient output power, low fuel consumption, minimal

maintenance requirements and extended service life. Features for precise control and enhanced operator comfort, are key to product advancement.” Doosan DX340LCA hydraulic excavators have new technologies that deliver effective control over each machine’s power and also simplify maintenance procedures. As a result, efficiency and machine durability are increased, productivity is improved and operational costs are lowered. These high strength excavators have a new 6-cylinder water cooled engine that is optimised and electronically controlled to boost production, maximise fuel efficiency and ensure harmful emissions remain well below the values required for Tier II engines. Rated engine power is 185 kW (247 HP) at 1 800 rpm and maximum torque is 114 kgf.m at 1 400 rpm. Improved cooling performances reduce fuel consumption and minimise noise levels in heavy duty and hot working conditions.
