Product Description

High Efficiency ZOOMLION Rotary Drilling Rig ZR280C in Good Quality

• Zoomlion’s specific-use in house undercarriage perfectly matches power systems with hydraulic systems, using the world’s leading load-sensing proportionally controlled hydraulic systems, which helps to achieve higher efficiency;
• The mast’s leveling monitors verticality accuracy of the Kelly bar to ensure verticality of the borehole.
• World-class components are used to achieve excellent performance;
• Optimized structures such as luffing mechanism, etc. allow the machine to be easier for removal or maintenance;
• The mast uses large-arc bending-forming structure with high strength, light weight and good stiffness. The unique separate lubrication path and anti-seize mechanism of the mast turntable allow the machine operation to be more stable and extend the machine life.
