SANY SR275 Rotary Drilling Rig - Efficient & Stable Solution for Large-Diameter Pile Engineering

Application

The SANY SR275 has the advantages of strong power, strong stability, efficient construction capabilities, easy operation, convenient maintenance, high-quality manufacturing technology and reliability. It is an excellent tool widely used in earthwork projects.  

Features

1. Powerful Core Drilling Capacity
Equipped with a 275kN·m high-torque power head and a high-performance 260kW engine, it provides strong and consistent power output. The machine offers 240kN crowd force and 260kN pull-up force, enabling efficient and smooth drilling of deep and large-diameter piles, with outstanding adaptability to hard and complex geological layers.

2. High-Efficiency Construction Performance
Featuring a high-speed main winch with a maximum line speed of 75m/min and an optimized fast soil-dumping system, it significantly shortens single construction cycles. The adjustable power head rotation speed (4-30rpm) can be precisely matched to different geological conditions, maximizing drilling efficiency and reducing overall project duration.

3. Heavy-Duty & Ultra-Stable Structure
Built with a 90-ton heavy-duty operating weight and a reinforced telescopic crawler chassis, it has a low center of gravity and exceptional operational stability. The high-rigidity box-type mast and wear-resistant key components ensure long-term durability under high-intensity working conditions, minimizing equipment failure rates.

4. Intelligent & User-Friendly Operation
Configured with an advanced 10-inch HD intelligent touch control panel, it supports real-time working parameter monitoring, fault self-diagnosis and one-key precision operation. The ergonomic, sound-insulated cab with comfortable seating and flexible control handle reduces operator fatigue, suitable for long-hour continuous construction.

5. Flexible Mobility & Convenient Transportation
Adopting a retractable crawler chassis design, it offers flexible movement and steering on construction sites, adapting to narrow and confined working spaces. The compact whole-machine layout allows for integrated transportation without large-scale disassembly, simplifying site transfer and reducing transportation time and costs.
