Features
  • Stable Drive System The bulldozer adopts a closed hydrostatic system equipped with Linde/Rexroth components, specifically optimized for pressure balance in the 120HP class. The system ensures fast and stable power response without performance drop even under extreme heavy-load conditions.

  • All-Terrain Load Adaptation The intelligent control system detects dozing resistance in real time and automatically adjusts engine speed accordingly. The system provides precise torque distribution when handling high-capacity bulk materials with a 3.0 m³ blade, significantly improving overall working efficiency.

  • Versatile Control & Stepless Speed Operation The bulldozer combines electro-hydraulic single-lever control with a 0-10 km/h stepless speed system. This configuration allows smoother switching between forward and reverse movements, effectively reducing cycle time and improving productivity on large construction sites.

  • Reliability for Demanding Environments The bulldozer is built with a reinforced chassis and high-standard waterproof braided wiring harnesses for enhanced durability. LED lights come as standard, ensuring stable continuous operation in harsh environments such as mines, ports, and heavy-duty construction sites.
