Precise alignment with holes JINT SD28 Rotary drilling rig

Strong geological adaptability, efficient rock penetration from soft soil to moderately weathered rock

286 kN · m high torque+wide speed regulation: suitable for clay, sand, gravel layers and moderately weathered slate/limestone, with a rock penetration efficiency 10% -15% higher than ordinary models of the same level, and a high one-time porosity rate.
Power head with three motors/three reducers configuration: Strong impact resistance for hard rock drilling, reducing boring and stuck drilling, drilling verticality ≤ 1 ‰, meeting high-precision requirements for subways and bridges.
Engineering case verification: Dalian Financial District weathered rock, Kunming Dacheng Financial Center 64-68m deep hole (Φ 1.5m) daily average of 2 holes formed, leading in efficiency.

Solid and reliable structure, stable and low maintenance under heavy loads

JT80 expandable track chassis: track width of 800mm, telescopic width of 3.3-4.4m, three toothed track shoes, low center of gravity design, balancing stability and transportation convenience.
Three section foldable drilling mast+double boom structure: anti torsion and anti impact, no deformation during deep hole construction, good roundness of the aperture, reducing the difficulty of lowering the steel cage.
Single row rope main winch+centralized lubrication: The steel wire rope wears evenly and has a long service life; Maintenance free hinge points reduce manual maintenance, and the equipment attendance rate is ≥ 90%.
Lateral arrangement of engine: large maintenance space, convenient daily maintenance, and reduced downtime.

Intelligent control with precision, ensuring both safety and efficiency

Paifen automatic/manual leveling system: automatically adjusts the verticality of the mast, quickly positions on complex sites, and ensures safer and more efficient construction.
Timely control of hydraulic system for full power load: dynamically matching power output, reducing energy waste, and saving more than 15% energy compared to similar models.
Visual intelligent control: Real time display of hole depth, torque, fuel consumption, fault codes, supporting drilling parameter memory, even beginners can quickly get started.
Full dimensional safety protection: power head torque limit, automatic pressure limit, overload prevention, anti overturning, 360 ° panoramic monitoring, providing peace of mind for construction in urban core areas.

Multi method full coverage, one machine for multiple uses, reducing costs and increasing efficiency
Basic construction method

seamless switching between oil cylinder pressurization/winch pressurization, suitable for rapid construction in conventional geological formations.
Extended construction method: supports long casing, pipe rolling machine, CFA (Long Spiral Grouting), to cope with complex formations such as backfill soil, quicksand, karst, etc.
Full casing construction capability: The power head can directly drive the casing, which is suitable for strata with high risk of collapse, and the quality of pile formation is more stable.
Multiple drill pipe options: Friction resistant/self-locking drill pipes are available, suitable for different hole depths and geology, with flexible transition.
