highly adaptable SANY Sr155 Rotary drilling rig

Efficient and flexible, fast construction

The torque and speed of the power head are matched reasonably, and the main hoist speed is fast (80m/min), with a hole forming efficiency about 15% higher than that of the same level
Compact body, small tail turning radius (3715mm), strong adaptability to narrow urban construction sites
Crawler telescopic chassis, easy to transition, no need for frequent disassembly and assembly, with obvious advantages in frequent movement of projects

Economically energy-efficient and cost-effective

The engine and hydraulic system adopt power optimization control, and the comprehensive fuel consumption is 10% -15% lower than that of the same level
Single row rope main winch, with minimal wear and long service life of the steel wire rope; Centralized lubrication, with fewer maintenance points and lower maintenance costs
Medium sized machines are positioned with lower purchase and production costs compared to large machines, resulting in a shorter payback period

High reliability and strong durability

The mast adopts a box structure with strong resistance to torsion and fatigue
The sixth generation drill pipe has upgraded its material and retaining ring, resulting in a 25% increase in overall strength and outstanding drilling ability in highly weathered rocks
Key hydraulic and electrical components are sourced from international brands, with low failure rates and stable continuous construction

Intelligent upgrade, user-friendly operation

Equipped with Sany intelligent control system as standard, it integrates automatic vertical adjustment, drilling depth monitoring, and fault diagnosis
Comfortable cab, suspended seats+large screen, easy to operate, reducing labor intensity
Support remote monitoring and data management, facilitating equipment scheduling and after-sales diagnosis

Multi functional and widely adaptable

Supports multiple configurations such as friction rod, machine lock rod, long spiral, sleeve, and tube rolling machine, making it versatile for one machine
Suitable for various strata such as clay, sand, gravel, and strongly weathered rock
Applicable scenarios: building pile foundation, municipal pipeline network, subway enclosure, small and medium-sized bridges, photovoltaic foundation, etc
