Sufficient torque Sr235 Rotary Drill Rig

Efficient construction: sufficient torque, significant acceleration

The rated torque of the power head is 235 kN · m, and the speed is adjustable from 5-32 rpm, suitable for multiple layers ranging from soft soil to moderately weathered rock, with high efficiency in rock fragmentation and slag removal.

Full stroke 15000 mm pressurization system (some sub models have a short stroke of 5000 mm), with a pressurization force of 210 kN and a lifting force of 270 kN. Long stroke reduces the number of lifting rods and improves efficiency.

The EP control system distributes power in real-time, resulting in higher power utilization and an approximately 20% increase in soil construction efficiency.

The main hoist has a lifting force of 235 kN and a speed of 70 m/min, allowing for rapid drilling and soil throwing, reducing auxiliary time.

2. Reliable and durable: Strong structure, long lifespan

The sixth generation 445 new material drill rod+integral pressure platform improves drilling capacity by about 25%, with better fatigue and wear resistance.

The mast and amplitude are welded and heat-treated to high standards, and can work for 20000 hours without cracking, adapting to high-strength working conditions.

The single-layer winding and pre tensioning technology of the machine lock rod steel wire rope avoids tangled and twisted ropes, and extends the service life of the steel wire rope.

Centralized automatic lubrication system, scheduled maintenance of key parts, reducing manual maintenance and lowering the probability of failure.

3. Intelligent control: precise and convenient, lowering the threshold

The industry’s first RFID technology, automatic positioning of the power head pressure table, improves the efficiency of finding the table by about 50%, and reduces misoperation.

The floating pre tightening function automatically compensates for the clearance between drill rods, resulting in better verticality of the pile, making it suitable for high-precision foundation construction.

The intelligent display screen integrates data monitoring and fault diagnosis, with an intuitive operation interface that is easy for beginners to learn and reduces training costs.

4. Wide adaptability: multiple construction methods, multiple scenarios

The maximum drilling diameter is 2000 mm (without casing)/1500 mm (with casing), and the maximum depth is 68 m (friction rod)/54 m (machine lock rod), covering most of the needs of industrial and civil construction as well as small and medium-sized bridges.

The mast has a tilt angle of 5 °/90 ° in the front and back, and ± 3 ° in the left and right, which is suitable for construction on slopes and narrow sites, and improves the adaptability of working conditions.

Support special construction methods such as CFA and casing follow-up, and can customize low clearance attachments to meet the needs of complex urban environments.

National III/Euro V dual versions are available, with Euro V version (SR235M) having a power of 265 kW and adapting to the international high-end market emission standard S.

5. Economic energy saving and convenient maintenance

Isuzu/Volvo engines have strong power and optimized fuel consumption, combined with power distribution technology, reducing fuel costs by about 15%.

Modular design+universal accessories, easy maintenance, mature Sany global service network and second-hand equipment supply chain, easy procurement of accessories, and short downtime.
