It introduces the back-inclination large triangle structure with stationary luffing support, which is suitable for working conditions of low-tonnage drilling rig, improving the rigidity of working mechanism and enhancing the stability of whole drilling rig while achieving easy transportation;

The imported Kawasaki hydraulic parts can achieve reasonable powertrain matching and high construction efficiency;

The imported Cummins engine can minimize fuel consumption with the help of two optional accelerator control modes;

The working amplitude of auxiliary winch is increased, which can hoist light and small objects and save cost as well;

The main winch is designed with a high displacement motor, achieving more sensitive response and more reliable working and also getting rid of the difficulty in earth dumping for pile holes of small diameter;

The standard reducer joint can adjust drill rod combination according to actual conditions, thus effectively reducing fuel consumption and improving construction efficiency;

It introduces the proprietary intelligent control system, CAN bus and PLC, including automatic/manual adjustment of drilling mast verticality, depth automatic detection and display, intelligent fault diagnosis and control.
