Product Description

zoomlion Rotary Drilling Rig ZR280C-2

• Version 2.0 power matching and limit load control technology, working efficiency increased by 10%.

• 2 speeds push/pull crowd cylinder, efficiency increased by 20%.

• One button for soil-discharge, one button for hole-cleaning to ease the operations.

• Equipped 22 self auto-check , safety and performance monitoring.

• The supporting Angle of the mast cylinder increased 2 times, and the center of gravity of the whole machine is reduced by 60mm, which greatly improves the working stability.

• VI generation rotary head, three-stage buffer device, three-stage shock absorption measures, greatly reduce the vibration of the whole machine when working.

• 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.
