High drilling torque, High pressuring, and high construction efficiency.
Simple installation and convenient construction.Hoisting and pressurizing, long stroke is suitable for the working
condition of lower guard tube and long spiral.
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.
