Product Feature
Rotary Drilling Rig ZR220A
• The main winch is located underneath the mast,making it very convenient to observe the walking rope;
•
The over-loading proof device of the crowding system can protect the
Kelly bar effectively and make full use of capacity of the machine to
ensure verticality of the borehole;
• Zoomlion’s specific-use
in-house telescopic-crawler undercarriage is used to achieve superior
stability and transport convenience;
• The automatic engine power
control system jointly controls engine speed, hydraulic system pressure
and main pump displacement to protect the engine to the most extent,
making the engine more economic, efficient, reliable and keeping the
machine in the optimum operating status;
• Drilling tools for
different purposes with 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.
