Rotary Drilling Rig SANY Sr285 Construction complex terrain

Superb Power and Rock Drilling Capability

Equipped with an Isuzu 6WG1 engine with a high power of 300kW and a rated torque of 285kN·m, improving hard rock construction efficiency by approximately 10%.
With a crowd force of 260kN, pulling force of 335kN, and main winch lifting force of 330kN, it delivers outstanding rock drilling and rod extraction performance.
The 6th-generation drill pipe + integrated pressurized platform ensures strong penetration in hard rock and pebble layers with low failure rate.

Large Drilling Depth and Diameter, Covering Mainstream Large Pile Projects

Maximum drilling diameter of 2300mm, maximum depth of 94m for friction kelly bar and 61m for interlocking kelly bar, suitable for large pile projects such as high-speed railways, cross-sea bridges, and super high-rise buildings.
15m ultra-long pressurized stroke, compatible with long casing construction, and adaptable to complex formations such as beaches, pebbles, and backfill soil.

High Efficiency and Energy Saving, Low Comprehensive Cost

SYMC controller + EP power distribution ensure smooth combined movements and fast soil unloading, reducing overall fuel consumption by 10%–15%.
The floating pre-tightening function protects the wire rope and extends its service life; centralized automatic lubrication reduces maintenance time.

Adaptability to Multiple Construction Methods and Working Conditions

Supports mainstream construction methods including rotary drilling, continuous flight auger (CFA), secant pile, and deep mixing.
Low-headroom mode enables operation under bridges and indoors; drill pipe visualization prevents damage to drilling tools caused by misoperation.

Intelligence, Safety and Reliability

High-definition intelligent touch screen with real-time parameter monitoring, 3ms refresh rate, and smooth operation .
Overload protection, tilt alarm, turntable locking, and remote diagnosis reduce downtime risks SANY.
100-tonne heavy-duty chassis with 4500mm expanded track width and 4600mm tail turning radius, providing strong anti-overturning performance.
