The 2024 SANY SR255 Rotary Drilling Rig is a high-performance piling machine designed for large-diameter bored pile construction. It combines powerful rotary torque, advanced hydraulic technology, and a reinforced crawler chassis to deliver excellent drilling efficiency in demanding foundation engineering projects.
This model belongs to SANY’s medium-to-large rotary drilling rig series and is widely used in infrastructure construction such as bridge foundations, high-rise buildings, metro lines, and highway projects. The machine supports both friction Kelly bar and interlocking Kelly bar configurations, allowing operators to adapt to different geological conditions including clay, sand, gravel, and weathered rock.
The SR255 piling rig features an intelligent control system that provides real-time monitoring of drilling parameters, improving operational precision and safety. Its heavy-duty mast structure and large-diameter slewing bearing enhance machine stability during deep pile drilling operations. Powerful engine output and high rotary torque enable the rig to drill large piles with high efficiency and consistent performance.

Why Choose Used Construction Machines?
1. Cost Savings
Used construction machines are significantly more affordable than new equipment, allowing contractors to reduce initial investment and improve return on investment. This is especially beneficial for short-term projects or companies with limited budgets.
2. Faster Availability
Used machines are usually available for immediate purchase and deployment, eliminating long manufacturing and delivery lead times. This helps contractors start projects quickly and avoid costly delays.
3. Proven Performance and Reliability
Many used construction machines have a well-documented service history and proven field performance. When properly inspected and maintained, they can deliver reliable operation comparable to new equipment at a much lower cost.
