Advantage introduction

Optimizing the center of gravity of the entire machine,reducing the height of the center of gravity, increasing effective pressure,and improving the efficiency of rock entry.
The new generation rotary drive has added a two-stage buffer,which has a higher structural strength and makes the equipment more stable when entering the rock;Extended guidance for higher rock penetration accuracy.
