Superior Performance
Classic Model
With 250 kN.m Torque, the piling rig SR250 is mainly used in medium and small-sized bored piles of civil engineering (diameter ranging from 1.0m to 1.5m, depth less than 50m), it is suitable for clay, pebble layers, and highly weathered rock.
High Efficiency
Main winch confluence technology, the maximum speed reaches 63m/min; The construction efficiency is increased by 15% compared with competitors. Super large crowd force can realize fast drilling.
Flexibility
Spacious cab, comfortable seat, flexible joysticks and intelligent control system
Low Cost
Low Fuel Consumption
Engine output power intelligently matches the needs of system, fuel consumption is decreased by 5-10%.
Convenient Service
Short servicing time provides high profit.
High Reliability
Fine Production
Full-automatic production line and robot welding ensure high quality; All the key components are jointly designed by world famous manufacturers and are customized.
Rigorous Testing
100% nondestructive test of key components ensures high quality, stability and excellent performance of piling rig SR250.
