Fast dynamic response SANY SR285 Rotary Drill Rig

Core construction performance

Abundant torque and strong rock penetration ability
Rated torque of 285kN · m, power headband with adaptive rock entry technology, intelligent matching of torque and pressure; Soil layers, pebbles, and moderately weathered rock layers can all be efficiently drilled, and the versatility of soft and hard strata is strong.
Large aperture deep hole construction
The maximum pile diameter is 2.2-2.3m; the maximum drilling depth of the friction rod is 94m, and the machine lock rod is 61m, suitable for bridge, housing construction, and municipal deep pile projects
The sixth generation integrated lock rod drill rod
Strengthening the locking ring and high-strength pipe materials can increase drilling efficiency by about 10%; Visual display with drill rod locking, reducing the risk of drill rod accidents and wear
Step type main winch drum
Single layer winding of steel wire rope, no compression wear, and a 35% increase in steel wire rope lifespan; The main winch has high lifting force, fast lifting speed, and high drilling efficiency

Power and energy-saving advantages

Power optimization control system
Intelligent dynamic distribution of engine hydraulic power, smooth compound action, high power utilization, and lower fuel consumption; Fast response of heavy-duty construction power and good economic efficiency for long-term continuous operation
Long term durability capability
Can support daily high-intensity construction for long periods of time, with a continuous monthly average working hour of over 19 hours on the construction site, suitable for projects with tight deadlines

Reliability and structural characteristics

Anti vibration heavy load structure
The key components such as mast, variable amplitude, and power head are designed with rock penetrating impact and fatigue resistance; The hydraulic system is equipped with buffer protection, which reduces rock construction vibration and prolongs the overall lifespan of the machine.
Sany special widened chassis
Adequate counterweight, high stability of the whole machine, good verticality of deep hole and large pile diameter construction holes, and strong anti rollover ability.
Ultra long warranty, early industry 3000 hour warranty, large inventory of accessories, easy maintenance in the later stage, high resale value
