Product Description

Rotary Drilling Rig ZR280C-2 Piling Machinery Drilling Rig Adopts Big Flow Main Pump

• Rotary drive with three motors, which ensures large torque, high reserve coefficient and stronger construction capacity.

• High construction efficiency due to big flow main pump, multi-gear rotary drive, and two-speed crowd cylinder.

• More stable structure and stronger bearing capacity due to large supporting angle of the mast cylinder, lower center of gravity, and reinforced chassis.

• New generation cab with better vision, more comfortable operation, new electrical control panel. 360 degree full view monitoring.
