ZR300D rotary drilling rig is a high-performance, high-reliability piling product designed and developed by our company with years of technological achievements in design and manufacture of foundation construction machinery and in combination with international advanced technology, in order to adapt to market demand. This high-tech product with highly integrated mechanical, electric and hydraulic systems is widely used in all fields of China's infrastructure construction thanks to its excellent maneuverability, huge drilling & lifting capacity. It is applying to pile foundation projects of the construction such as railroads, highways and bridges.
Fixed mast support. Equipment can be transferred easily and quickly.
Rotary drive with three motors, which ensures large torque, high reserve coefficient and stronger construction capacity.
High construction efficiency thanks to big flow main pump, multi-gear rotary drive.
More stable structure and stronger bearing capacity thanks 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 controlpanel.360 full view monitoring.
Options: Auto-lubrication, spin-off.
