1. The machine is equipped with turbocharged engine, which is characterized with strong power and stable performance, oil consumption being 10%-20% lower than other engines.
2. It is equipped with Germany Rexroth or Germany Linde open & close circuit hydraulic system, with large flow, being good at anti-pollution, long lifespan and reliability.
3. Equipped with imported electric proportional motor, the machine contains simple gear transmission structure, reliable performance, and push-pull infinitely variable speed, top rank in working efficiency. The power head is reserved with reinforcement device(push-pull), and the push-pull force can reach 1750KN.
4. It is equipped with imported electric proportional motor, and the rotation is infinitely variable speed, which can improve working efficiency greatly.
5. Korea Jesung excavator contains double speed, its max. walking speed can reach 5km/h.
6. Low clamping center protects the drill rod effectively, and takes up small construction space. Front and back clamps are separated, and the clamping can change block according to drill rod specification.
7. It is equipped with φ114×6000mm or φ127×6000mm drill pipe. Floating spindle can further protect the drill pipe thread.
8. Four bar luffing mechanism is adopted, with big angle (10°-18°). The low gravity center makes the machine stable.
9. Wire-control ensures the safety of rig and people during walking, and the convenience of transition, loading and uploading.
10. Fully open mechanical hand makes drill rod slip automatically, and there is no need to unload drill rod with people, which saves labor charges.
11. Enlarged cab, with warm/cool AC, can be lifted up and down.
12. Liquid crystal man and rig exchange system can monitor rig condition at any time, which can adjust rig work, making operation simpler and more comfortable.
13. Intelligent program control system comfort makes the machine be with able operation, stable performance, and strong function extension.
