XCM Excavator XE470C
1. Bucket capacity: 1.9m3
2. Max. Digging force: 271KN
3. Operating Weight: 461000
1. Top equipment: All hydraulic parts: Hydraulic pump, main valve, rotary motor, travel motor, oil cylinder, pilot control valve and other components are world famous brands, ensured the product with very good quality
2. Adopting the latest advanced technology, lower energy consumption, high working speed and high efficiency
3. The arm and boom locking function, which prevent the boon and arm sinking, extending the medium position riding time.
4. The boom oil return and regeneration: The boom drawing back speed is much fast and stably
5. Strong and precise slewing control: The vibration absorbing character is improved; Assuring the slewing stop action has more accuracy and stability. Increasing the torque reserve to supply the machine with much powerful slewing ability.
6. The cylinder has a buffering function: The boom cylinder and bucket cylinder is designed with the buffer, reducing the machine vibration and shock, reduce noise and prolong oil tank life:
7. Double-pump concourse technology: Increase the main valve flow supply to the boom and the bucket cylinder, increase operating speed
8. The walking pilot valve is equipped with hydraulic vibration damper device: Machine startup, travel, and stop is much smoother.
