SR285 rotary drilling rig is a classic model features with high efficiency, low fuel consumption, smart and flexible, suitable for hard soil drilling, cast-in-place pile foundation work in civil engineering.
High drilling capacity
Powered by Mitsubishi engine with rated power of 300 kW@1800 rpm, SR285 power efficiency is significantly improved.
Kelly bar is made of high strength steel tubes with light design. Maximum output torque reaches 285kN.m, maximum pile depth of friction Kelly is 93.5m, pile depth of interlocking Kelly is 61m.
New design of main winch delivers faster line speed of 70m/min, bigger lifting power with 330kN line pull.
Safe and reliable
The 5th generation rotary drive adopts multi-gear control, self-adaptive techniques, and double buffering system which can increase drilling efficiency and safety.
ADMS intelligent operation system, advanced hydraulic system and heavy wide chassis ensure efficient, safe and stable operation.
Advanced welding robots, CNC automatic cutting machines ensure high precision and quality of the core components.
Easy to transport&operate
Compact in transport height and weight, the drilling rig is easy to transport in cities.
The tailored chassis with larger spaces for pumps and valves is for easy maintenance during work.
Spacious cab with panorama sunroof is designed to give the operator a comfortable environment and wide visibility.
