High verticality of hole‑forming SANY SR360 Rotary Drilling Rig

1. Strong rock drilling capacity

360kN·m high torque and 290kN crowd force, it can steadily drill into hard rock above 60MPa. The power head features multi-speed gear and adaptive rock control, automatically matching torque and crowd force. It performs well in sandstone and granite strata, serving as the main model for medium & large diameter rock drilling. Max pile diameter 2.5m, friction rod max depth 100m, interlock rod max depth 65m, suitable for building, bridge and high-speed railway foundation pile works.

2. High efficiency with excellent winch performance

The main winch adopts dual motors and dual reducers with a maximum rope speed of 75m/min for fast lifting and soil unloading. The stepped single-layer drum arranges steel wire rope in a single layer under interlock rod working conditions without extrusion and abrasion, extending wire rope service life by about 35% and reducing downtime for rope replacement.

3. Stable and reliable with robust structure

Box-type mast and luffing mechanism feature vibration resistance and anti-fatigue performance. Wide retractable crawler chassis with low gravity center avoids tipping and shaking during deep hole and large diameter construction. Core hydraulic components and reducers have sufficient safety margin, adapting to long-term rental and high-intensity continuous operation. Structural parts keep intact even after 20,000 working hours.
