[Effective Excavation Method for Parts of Liugong Excavator]

When the bucket cylinder and connecting rod, bucket cylinder and bucket rod are hundreds and 90 degrees each other, the digging force is great.

When the bucket teeth and the ground are kept at an Angle of 30 degrees, the digging force is the least resistance to soil cutting.

When excavating with bucket rod, the Angle range of bucket rod should be guaranteed from 45 degrees in the front to 30 degrees in the back.
