cummins

CUMMINS high-power engine with strong power, low fuel consumption and high reliability.

The system incorporates a large-bore hydraulic cylinder with an optimized linkage configuration, enhancing force transmission efficiency across critical joints. Its intelligent load-sensing mechanism automatically activates pressure compensation when external resistance increases, delivering progressive digging force amplification through closed-loop hydraulic regulation. This adaptive power optimization ensures consistent performance under varying operational conditions while maintaining system protection.

Large displacement slewing motor and slewing gear design with large speed ratio Higher starting torque, better slewing braking effect.

Intelligent electronic monitoring system, real-time monitoring, self-diagnostic fault alarm, maintenance information prompts.

Adopting safe and reliable new cab, brand-new injection molding interior parts, beautiful and generous, spacious and comfortable, equipped with full-automatic cold and warm air-conditioning.

Humanized centralized and remote ground maintenance design, lighter maintenance.
