Product Overview
The SM280 Hydraulic Crawler Water Well Drilling Rig is a seamless upgrade from the SM260 model, designed for contractors who need greater drilling depth, stronger lifting capacity, and higher torque without sacrificing mobility or operating cost control.
Positioned in the 250–300m water well drilling segment, SM280 is ideal for users who have already worked with 200–260m rigs and are now facing more complex geological conditions, thicker overburden layers, or projects requiring deeper and more stable boreholes.
Built on the proven SM260 platform, SM280 delivers enhanced structural strength, optimized hydraulic performance, and wider configuration compatibility, making it a reliable solution for agricultural irrigation, rural water supply, municipal projects, and contractor-based drilling services.
Why Upgrade from SM260 to SM280
Compared with SM260, the SM280 drilling rig offers:
Extended drilling depth: from 260m to 280m, covering a wider range of groundwater projects
Higher lifting force: improved main rig lifting capacity for deeper casing operations
Stronger rotary torque: better performance in gravel, weathered rock, and mixed formations
Longer one-time feed stroke: improved drilling efficiency and reduced pipe handling time
Better adaptability to medium and high air pressure DTH drilling systems
This makes SM280 the preferred choice for contractors seeking higher productivity and future-proof capability while maintaining a familiar operating experience.
