Product Advantages

1. Power & Efficiency Advantage

Adopts internationally renowned upgraded Isuzu 6HK1XQP engine, featuring higher power, lower noise, lower fuel consumption and stronger reliability. The advanced full hydraulic control system realizes precise control of the power head and winch, improving drilling efficiency by 23% compared with similar products in the same class, effectively reducing the comprehensive operation cost for customers. The engine adopts upgraded turbocharged intercooling and electronic injection technology, ensuring stable power output even in high temperature, high altitude and other harsh working conditions.

2. Structural Stability Advantage

SANY self-developed SY480Rs upgraded chassis is made of high-strength alloy steel, with optimized structural design and stronger bearing capacity. The 800 mm wide track shoe increases the contact area with the ground, effectively preventing the machine from sinking in soft soil and muddy construction sites. The 4600 mm extended track span further enhances the overall stability of the equipment during high-altitude operation and deep drilling, avoiding tilting risks and ensuring construction safety, which is more stable than the base SR235 model.

3. Drilling Adaptability Advantage

With max drilling diameter of 2500 mm and max drilling depth of 72 m (friction kelly bar) / 58 m (interlocking kelly bar), it can flexibly meet the construction needs of different large-scale foundation projects. It can efficiently cope with various complex strata such as clay, sand, weathered rock and hard rock, eliminating the need for additional equipment transformation, reducing construction difficulty and improving construction quality and efficiency, with better adaptability than the base model.

4. Reliability & Durability Advantage

All key components (engine, hydraulic system, winch, kelly bar) are selected from well-known international brands and upgraded for better performance, with mature technology and strict quality control. The whole machine undergoes rigorous fatigue testing and environmental adaptability testing before leaving the factory, with strong wear resistance and corrosion resistance. It can operate stably for a long time in harsh working environments, reducing the frequency of maintenance and downtime loss, and improving equipment utilization rate.

5. Operational Convenience Advantage

The humanized operation cab is equipped with a comfortable adjustable seat, air conditioning and an intuitive digital operation interface, which is easy to learn and operate, reducing the labor intensity of operators. The key maintenance parts (engine, hydraulic oil tank, filter) are designed with easy access, simplifying the maintenance process, shortening maintenance time, and reducing maintenance costs. The whole machine adopts flexible walking and leveling system, which is convenient for moving and positioning on complex construction sites, with optimized operation smoothness.

6. Environmental Protection & Compliance Advantage

Complies with EU Stage III / EPA Tier 3 emission standards, which is environmentally friendly and energy-saving, avoiding environmental protection risks for customers in international projects. The drilling process adopts mud recycling technology, reducing environmental pollution and keeping the construction site clean. At the same time, the low-noise design of the engine and hydraulic system meets the noise control requirements of urban construction and other scenarios, with further optimized noise reduction effect compared with the base model.
