Product Feature
Rotary Drilling Rig ZR280A-1
• 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.
