SR150C Rotary drilling rig Contents Rotary drilling rig is widely used in urban high-rise buildings, railways, highways, bridges, airports, ports and other bored pile foundation construction, features wide application range, high working efficiency, stable performance perfect customer support, energy saving and environment- friendly, which now has became the most famous brand in China. Electrical system Integrated circuits Integrated circuits eliminate wire connecting failures, and also bring convenient maintenance. SYS Monitor machine working conditions and improve operation safety. GPS Remote Monitoring Realize remote customer support with wireless transmission of data. 3G communication technology greatly increases the transmission speed and transmission capacity. Realize remote recording and fault diagnosis with complex fault diagnosis algorithm. M2M fleet service. GPS, wireless networks, mobile link. Hydraulic system Sophisticated hydraulic system Save energy and realize accurate action control. Main loop adopts sophisticated negative hydraulic control system and assistant loop adopts advanced load-sensitive control system, which saves energy and ensures accurate action control. Negative hydraulic control system Ground touching protection Prevent the wire rope from disordering when the main winch is rapidly releasing. When the drilling bucket is released to the pile hole bottom, controller of the hydraulic system automatically cuts oil supply to the main winch motor, avoids wire rope disordering caused by over-releasing. Load sensitive control system Main winch automatic releasing control Releasing speed increased by 50%. Main winch wire rope releasing adopts hydraulic confluence technology, which doubles the releasing speed and decrease ineffective working time. Main winch floating function Easy operation and manual controlled Floating function enables the drilling to be done without the hoisting of the main winch, which simplifies operation and saves energy. Mechanical system Wide application range, high reliability Considering the high gravity center and heavy weight, undercarriage adopts reinforced slew bearing to ensure stability while mast standing and lowering. Machine welded and high strength steel, undercarriage frame fulfils complicated rotary drilling requirements. Reasonable designing makes the best of robust Isuzu diesel engines output. Pumps like Kawasaki guarantee plenteous power supply at all the time Large box construction and imported material, the mast can effectively avoid crack and provide with expected service life. Kelly bar is made with high strength structural steel tube, and stress concentration area takes special structure, effectively prolongs service life. Brevini, Bonfiglioli rotary drive reducers and famous motors like Rexroth and so on, can adjust speed and torque output automatically according to the real geological condition, perform excellent working efficiency at any working condition. Sany provides on-site drilling tools modification and customized drilling tools developing to ensure high efficient drilling. High Reliability Safety equipments Various safety equipments provide comprehensive protection Cab anti-collision function: Avoids possible collision between mast and cab. Main winch monitoring system: Provides lighting and monitors the main winch real timely with a camera Radar slew protection: Camera and radar sensor eliminate the invisible zone, assure back off and slew safety. Caution light: Indicate the machine position and height. Anemometer: Measure the wind speed, avoid possible accidents caused by strong wind. Inclinometer TY-60: Measure the mast angle and ensure mast verticality. Gradienter SC0-3: Display undercarriage angle and ensure that the machine works at level position. Cord switch FD676: Limit auxiliary winch hoisting height and avoid the pulley yoke from collision. Unit Parameters Max. Drilling Dia. mm 1500 Max.
