Rotary Drilling Rig SWDM220-3

Overall height: 22.2m
Max. drilling diameter: 2.0m
Max. drilling depth: 69m

Suitable for civil construction and piling projects;

Main winch features high pull force and speed, the rotation speed of rotary head is high, providing excellent working efficiency;

Single-layer winding of steel rope for minimal rope wear, increasing 50% of rope life;

Heavy-duty retractable crawler undercarriage coupled with double cylinder luffing mechanism ensures the high stability and reliability;

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; Other assistance systems like audible / visible alarm and emergency stop button are available to assist operators in convenient and safe control for drilling process;

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;
