Adapt to complex strata SANY SR285 Rotary Drill Rig

Power and construction efficiency

Strong rock penetration ability: high torque power head, full stroke pressurization system, adaptive matching of torque and speed, outstanding performance in construction of hard soil, gravel, and moderately weathered rock layers, balancing deep pile and large-diameter operations
The sixth generation machine lock drill rod: with an overall locking structure and reinforced ring body, the drilling efficiency is improved by about 10%; Supporting optional locking rods and friction rods, with a maximum pile diameter of 2.2-2.3m and a maximum drilling depth of 94m
Step type main winch: The steel wire rope is arranged in a single layer to avoid compression wear, and the service life of the steel wire rope is increased by 35%. The lifting and lowering speed is also improved
Smooth compound action: power optimization allocation technology, multi action coordination without lag, good stability under high working hours, suitable for projects with tight deadlines

economy

Intelligent power matching: Engine power is distributed according to demand, with no fatigue under heavy loads and reduced fuel consumption under light loads. The actual fuel performance on the construction site is better than that of competitors in the same level
Good adaptability to oil products: The three-stage fuel filtration system can work stably even with low-quality diesel on construction sites, reducing filter element loss and failure rates
Multi method expansion: Standardized mast interface, which can quickly switch between rotary excavation, long spiral CFA, long casing, and low clearance construction. One equipment can undertake multiple pile foundation activities, improving equipment utilization
