SPECIFICATION
1. The main pumps are from world famous brand. Redesigned Hydraulic circuit makes the operating more easily, and the faliure rate decreased sharply.
2. The most mature hydraulic walking system is selected for its strong driving force and easy and fast to operate.
3. Big horse power could guarantee good pulling capacity. Double-pipeline four calipers brake is stable and safe.
4. Wide operation space has good vision and comfortable seat.
5. Reasonable dynamic match and excellent overall performance with superior operation efficiency.
6. Comfortable operation environment: omni bearing adjusted seat, monitor with an adjusted visual angel, high-performance air-conditioners, optimized arranged pipe ports.
7. Optimized design of Power, electric, hydraulic and laminate system. Easy to maintain and repair.
8. We could add gyrator and broken quartering hammer etc. according to customers’ requirements.
9. Some of the main structure parts adopt robot welding, such as the chassis and boom and arm. The endurance and safety are better.
10. Each rear support bracket is cased according tress analysis and fatigue testing, it is better to unit-break, then the service time is longer.
11. The key parts of Bucket bar is reforced, the surrounding of shaft housing are cast parts, which prolong the strength and the life span.
12. Connecting hole of the bucket also experience hardening treatment.
