Product Features & Core Strengths
Original Doosan Heavy-Duty Hydraulic System
- High-flow hydraulics reduce power loss and leaks; large radiator maintains steady temperature for all-day mining work.
High Torque Energy-Saving Turbo Diesel Engine
- Low-RPM high torque cuts fuel use by 18%. Reliable startup works for both cold mountain mines and hot tropical quarries.
Reinforced Heavy Chassis & Balanced Frame
- Wide tracks bear heavy loads on mud; adjustable steel tracks improve mobility over rocky quarry ground.
Wear-Resistant Reinforced Working Attachment
- Thick manganese steel welded boom, arm and bucket resist rock cracks. Standard mining bucket meets most heavy digging demands.
Humanized Sound-Isolated Operator Cabin
- Soundproof cabin with digital monitoring panel. Shock-absorbing seat eases fatigue during long shifts on rough sites.
