The birth of these products will lead wheel full circle swinging excavator to a new era. It will be sure to get your favor by means of its superior performance and cheap price. In addition, it will bring your more benefit reciprocations due to the convenient and fast operation.

The main characteristics are as follows:

1. Reliable and flexible mechanic movable performance, fast rotation could save your much more time.
2. Accessories are selected the world famous brands, which could combine with domestic hydraulic parts to assure the reliability of main machine and reduce products' cost.
3. Structural parts are made by our own company and the whole production is under monitor to be reliable and long-lasting. Main stressed parts are verified by finite element analysis and the snubbing unit adopts the optimized design. Key welding lines of overall machine are passed the undamaged flaw detection.
4. Comfortable operation environment: omnibearing adjusted seat, monitor with an adjusted visual angel, high-performance air-conditioners, optimized arranged pipe ports.
5. Optimized design of Power, electric, hydraulic and laminate system. Easy to maintain and repair.
6. We could add gyrator and broken quartering hammer etc. according to customers' requirements.
7. Some of the main structure parts adopt robot welding, such as the chassis and boom and arm. The endurance and safty are more better.
8. Each rear support bracket is cased according tress analysis and fatigue testing, it is better to unti-break, then the service time is longer.
9. The key parts of Bucket bar is reforced, the surrounding of shaft housing are cast parts, which prolong the strenght and the life span.
10. Connecting hole of the bucket also experience hardening treatment.
