1. Engine: Feed by hydraulic cylinder,the drilling efficiency is higher and it can save labor. 2. Drill rod: 53x59 drilling rod adopted,high rigidity and strong delivery torque. 3. Spindle: Vertical spindle are fixed by four groups of bearing to ensure that the rotary machine is rigid enough for gravel layer and other complex geological conditions. 4. Mud pump:Equip mud pump with flow 160L/min,save cost and also make the structure compact. 5. Concentrated handle, small footprint,light weight, strong decomposition, easy to move.
