Rotary Drilling Rig

Features:
1) The series of SANY rotary drilling rig are hi-efficiency pore-creating drilling equipment 
    for pile foundation construction, suitable for base foundation construction such as 
    high-rise buildings, bridges and hydraulic construction
2) With the advantages of famous brand drills at home and broad in design and 
    technique, it has the same performance parameters as the international-level 
    products of its kind. And the international brand-name products are employed for its 
    key components. The machine is convenient and efficient in operation, helpful for 
    environmental protection and energy saving, and beneficial to comfortable and safe 
    operations
3) The main body structure is designed rationally and has high hardness, which 
    effectively ensures the durability and firmness, and impact and vibration resistance, 
    especially the dynamic head can provide enormous torque, thus promoting the 
    operation efficiency
4) With multi-choice of drill rods, it can use various drilling bits and tools, resulting in 
    broad construction choice. It is suitable for construction in clay, gravel, pebble, 
    middle weathered stone and plateau frozen soil strata and can provide solution of 
    construction in the pebble bed which cannot be carried out by ordinary drills.   
5) Due to the adoption of CAT C-9 electrojet turbine engine with supercharged 
    intercooler, it has high reliability and economical fuel consumption
6) Auto acceleration/deceleration functions, resulting in 5-10% fuel costs reduction
7) Once operation stoppage, the speed of engines will automatically decelerate to 
    save fuels, and when restarting, the speed of engine could automatically resume to 
    its setting value
8) Reliable system assurance: the international brand-name Rerxroth hydraulic system 
    and electro-hydraulic pilot control can automatically adjust the verticality of mast, 
    EMC e-module real-time monitoring, 16 alarm functions, PLC program controlling 
    working state of drills and newly-designed safety cooling system can satisfy 
    working conditions and environment, also reliable Grade 3 alarm monitoring system 
    can guarantee normal operation of drills
9) The specially-recommended SR300 and SR250 SANY rotary drilling rigs with 
    enormous power can be widely applied in enormous and excessive deep piling 
    construction of foundation works, bridging the gap in rotary drilling rigs with 
    enormous power and excessive large caliber
10) Product models: SR128, SR168, SR220C, SR250, SR300
