Classic model

SR220 rotary drilling rig for small and medium-sized industrial civil construction, municipal and railway pile foundation projects, is widely used in clay layer, pebble layer, mudstone layer and other medium and strong weathering geology of the pile hole construction equipment.

High efficiency

250kW engine, the largest mainstream model in the same class, provides more powerful power for the whole machine work, improve construction efficiency.

The power head torque is large and the drilling speed is fast.

The main hoisting force is large, the speed is fast, and the efficiency is higher when the civil construction is mainly constructed in soil layer.

High reliability

Core components are jointly designed with international well-known manufacturers, customized production for  rotary drilling rig, to ensure a high degree of matching;

Using advanced research and development means, using advanced finite element analysis software to carry out static analysis, dynamic analysis, fatigue analysis and test of the product, in order to meet the design requirements and optimize the product structure.

Automatic production line, robot welding, product quality is stable;

Key parts 100% non-destructive inspection, quality assurance;

Smarter, safer

Higher intelligence level, more safety protection, convenient construction operation, maintenance, troubleshooting and customer monitoring and management.
