Good Control: Doosan excavators feature improved joysticks for high-precision control, and new oil seals and durable materials have been adopted to reduce joystick leakage. Furthermore, the hydraulic system enables precise motion control, allowing operators to easily control digging direction and depth.

High Comfort: Doosan excavators feature user-friendly cab designs. For example, the DX420LC is equipped with a shock-absorbing suspension seat that can be adjusted fore and aft, side to side, and features high-strength suspension and lumbar support. It also features a large-capacity, fully automatic air conditioning system and a high-tech color LCD monitoring system, providing a comfortable working environment and reducing fatigue.

Durability: Doosan excavators utilize high-strength steel structural components. For example, the DX420LC's boom and arm are constructed of thickened steel plates, with large reinforcement ribs at the base and stress-bearing areas. The boom base is cast steel. Furthermore, the hydraulic cylinders utilize new oil seals and heat treatment technology, significantly improving the cylinder's rigidity and strength, enabling it to withstand harsh working environments and extend the equipment's service life. Easy Maintenance: Doosan excavators are designed to facilitate routine maintenance and component replacement. For example, the DX200-9C features an optimized accessory layout, making service and maintenance more convenient, and daily inspections can be easily performed from the ground. Furthermore, its oil filtration system boasts high filtration efficiency and strong adaptability to low-quality oil, reducing equipment failures and lowering maintenance costs.
