Product Feature
Rotary Drilling Rig ZR220C
• 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.
