Flexible operability is at the heart of the job. The NDI320 excavator utilizes the best Korean hydraulic system. The driver can distribute the oil evenly according to the operation requirements, so that the power arm, the stick and the bucket can be operated flexibly, quickly and efficiently. Realize what you really want.
The NDI320 is the “fuel-saving star” in the 30-ton class. And the power is strong, and the excavation work is solid and powerful. It is currently one of the best-selling models on the market. This type of excavator is often used in common earthwork construction, such as foundation excavation, road and railway subgrade construction.

1. Strengthening of main frame structure
The section is enlarged, the material is optimized andadjusted, the plate thickness is thickened, and the servicelife is increased;
2. X-shaped support, one-time formingnon splicingThe upper plate, the lower plate and the connecting rodof the chassis are all designed as a whole, effectivelyimproving the cracking problem caused by poor weldingin the field.
