• Zoomlion’s specific-use in-house telescopic-crawler undercarriage is
used to achieve superior stability and transport convenience.
• The over-loading proof device of the crowding system can protect the Kelly bar effectively and fully make use of capacity of the machine to ensure verticality of the borehole.
• Pilot and proportionally controlled hydraulic systems, load-sensing or negative-flow controlled main pump or auxiliary pump systems with high control accuracy help to achieve high efficiency and less energy loss;
• Zoomlion's patented high-accuracy depth measurement device whose accuracy is several times better than domestic or international competitions is used for automatic measurement;
• Drilling tools for different purposes with different specifications such as long or short augers, generic-use drilling buckets and core barrels, etc, are equipped to satisfy construction requirements in different geological conditions.
