Power head is connected using pin connection method for easy mounting and dismantling; Power box is 6-time sealed to prevent dirt and sand from entering;

Optimized hydraulic circuit arrangement contributes in reduced pressure loss and expanded space for easy maintenance;

Patented uppercarriage rotation brake technology, high strength mast material, double cylinder luffing mechanism and heavy-duty retractable crawler undercarriage, ensuring high anti-fatigue effect and extended service life;

Single-layer winding of steel rope on a large-diameter drum for minimal rope wear, increasing 50% of rope life;

Hidden type outrigger leg is located at bottom part of the mast, not only can enhance the stability during drilling but also facilitate daily maintenance of undercarriage;

Fault self-diagnosis and alarm, real-time display of drilling parameters, control unit with one-button locking, providing guaranteed operation safety;

Through mobile phone APP (cloud platform), operating data can be synchronously transmitted and the equipment status can be monitored via monitoring camera at any time;

Wireless remote control is optional to achieve remote control of travelling and luffing, keeping operator safe while giving a wider visibility for special working conditions;

Wide functional expansibility, can achieve multiple functions in one machine, e.g. continuous flight auger (CFA) pile construction, belled pile construction, large-diameter variable-section pile construction; Can be retrofitted to a DTH drilling rig with swivel joint to execute ultra large diameter deep hole reverse circulation drilling;
