Crawler Excavator ZE550EK-10
  • Strong power

ž   The Stage III CUMMINS engine is powerful, robust and durable.

ž   Three-stage automatic idling control, intelligent control and reasonable matching keep the engine RPM near the maximum torque working point to reduce fuel consumption.

  • Reliable and Precise Hydraulic System

ž   Professionally tailored hydraulic system meticulous matching with the power system guarantees reduced oil consumption and improved efficiency, thus providing precise and sensitive operation experience.

ž   Excellent slewing force and more sensitive simultaneous movements can be provided thanks to the large-torque slewing motor equipped on the machine.

ž   Procedural electrical control of hydraulic pump and refined control valve spool bring smoother operation, higher efficiency and more excellent energy-saving performance.

ž   Key hydraulic parts from world-known brands boasts high reliability and quality.

  • Reliable & Durable Machine Structure

ž   By adopting integrated large-profile design of structural parts, and heavy-duty design of slewing table and lower frame, strengthened key locations enjoys high durability.

ž   Integrated manufacturing of boom and stick reduces the risk of open weld.

ž   Refined D-ARCS bucket offers a better cutting angle and a more user-friendly digging experience. Wear resistance of the back board is strengthened by 40%.

ž   Durability design optimization of track rollers brings enhanced adaptability to harsh working conditions.

  • Comfortable & Intelligent Operation

ž   Spacious operation cab, 8% larger than the industry.

ž   Suspended seat provides a high level of operator comfort.

ž   The large-screen monitor is equipped with a brand-new human-computer interaction operating system. All recreational functions such as CANBus radio, USB and Bluetooth are available.

ž   The newly developed IPCS (intelligent power control) system, a controller for professional construction machinery, adopts the CANBus technology to achieve compound control of the engine, pump and hydraulic control valve, so that the power of engine and main pump can be brought into full play.

  • Convenient Maintenance

ž   All maintenance parts in centralized distribution are easily accessible, realizing one-stop maintenance to guarantee short maintenance times.
