5ton Used Komatsu PC56-7 Excavators For Sales

Intelligent energy-saving start-stop system: Equipped with advanced automatic idle control technology, when the control lever remains stationary for only 4 seconds, the engine immediately switches to idle operation mode automatically. Once the operation resumes, the rotational speed instantly rises back to the working state. This design significantly reduces the fuel consumption of the equipment when it is unloaded, and effectively minimizes the wear of mechanical components, achieving dual benefits of energy conservation and extended service life.
Optimized intelligent cooling system: The hydraulic oil radiator adopts an innovative, efficient and clean structural design, and is combined with a precise back pressure valve (precisely controlling the pressure to 0.25MPa) to form an intelligent temperature control mechanism. This system significantly reduces the alarm frequency under high-temperature conditions in summer. Even in the face of long-term heavy-load operations, it can ensure that the equipment always maintains a stable operating temperature.
Integrated control upgrade: The walking speed change switch has been innovatively integrated into the bulldozer scraper control lever, achieving synchronous operation of bulldozer operation and walking speed adjustment. This integrated design effectively simplifies the operation process and significantly enhances the smoothness of continuous work and construction efficiency.
