Smooth combined movements SANY SR285 Rotary Drill Rig

Power and rock penetration performance

Rated torque of 285kN · m, medium tonnage high torque model, outstanding construction ability in hard soil, gravel, and moderately weathered rock layers
The power head is equipped with adaptive technology for rock penetration, with intelligent matching of torque and pressure, making rock drilling smoother
Professional rotary drilling chassis+large counterweight, widened tracks, strong stability under heavy load in deep holes, high verticality of hole formation

Drilling efficiency advantage

The sixth generation machine lock/friction resistance drill rod has an overall locking structure, reinforced drilling ring, and increased drilling efficiency by 10%
Step type main winch drum, single layer winding of steel wire rope, no compression wear, steel wire rope life extended by 35%
Full stroke pressurization system, fast pressurization speed, reduces repeated lifting and lowering of drill rods, and accelerates the pace of deep hole construction
The maximum drilling depth of the friction rod is 94m, the maximum machine lock rod is 61m, and the maximum pile diameter can reach 2.3m, suitable for deep pile large hole projects

Energy saving economy

Power optimization control system, real-time power allocation, smooth composite action, lower fuel consumption
Strong adaptability of engine oil, three-stage fuel filtration, and stable operation of low-quality diesel on construction sites, reducing the risk of failure

Multi working condition expansion capability

Multi functional standardized mast interface, which can quickly switch between various construction methods such as ordinary rotary excavation, long casing, low clearance, and long spiral. One equipment can undertake multiple pile foundation projects, improving equipment utilization
SR285RW10 long casing version, with strong casing lifting force, can achieve deep casing self pulling without the need for auxiliary crane construction
