The reliability of an item of plant contributes to its overall lifetime operating costs.

DOOSAN uses computer-assisted design techniques, highly durable materials and structures then test these under extreme conditions.

Durability of materials and longevity of structures are our first priorities.

Reliability

Strengthened boom

The shape of the boom has been optimized by finite elements design, allowing the loads to be better distributed throughout the structure. This combined with increased material thickness means improved durability and reliability by limiting element fatigue.

Arm assembly

In the arm assembly greater strength has been gained by using cast elements and reinforcement around the bosses to give it an increased lifetime.

The D-type frame and chassis frame add strength and minimize distortion due to shocks.

cooler help demonstrate the best cooling efficiency and have also drastically improved the pressure resistance, vibration resistance and thermal strength.

lubricated metal is used for the boom pivot in order to increase the lifetime and extend the greasing intervals to 250 hours. a rolled bushing with very fine grooves has been added to the arm to bucket pivot, so that greasing is only required every 50 hours.

new materials have been used in order to increase the wear resistance and to increase the service intervals. The longevity is greatly increased by the addition of wear plates on the inside and the outside of the bucket lugs.
