Wheel-crawler excavator is totally invented by our company; the transportation cost can be highly reduced with this design. High transportation efficiency, it is convenient to operate and easy to switch the crawler and wheels.
1. Adopting world famous brand YANMAR engine, with strong driving force, low noise, low oil consumption, and more reliable.
2. Mature hydraulic system, Easy to operate. High working efficiency. Main hydraulic parts are imported from Korea, Japan. Stable working performance.
3. Structural parts are all made by our company; main parts are all under nondestructive inspection treatment, which ensure the parts' strength and stiffness. Main structural parts are treated by shot blasting, which increase the adhesion of painting, prevent from corrosion, and finally prolong the service time of the excavator.
