SM-300 Rig is crawler mounted with top hydraulic drive rig. It is a newly designed and produced style crawler drilling rig.
The rig is mainly use for diamond bit drilling and carbide bit drilling of solid bed. It also can be use in underpinning and pile drilling, geotechnical surveys drilling and mineral exploration drilling etc.
Key Features & Advantages
Top Hydraulic Head Driver: Driven by two high speed hydraulic motors, supplying great torque and a wide range of rotation speeds.
Feeding & Lifting System: Adopts hydraulic motor driving and chain transmission for a long feeding distance and convenient drilling.
V Style Orbit: Built in the mast to ensure sufficient rigidity between the top hydraulic head and the mast, delivering stability at high rotation speed.
Rod Unscrew System: Simplifies rod handling operations during drilling procedures.
Hydraulic Winch: Designed for lifting, offering improved lifting stability and excellent braking capabilities.
Electric Controlling: Equipped with a centralized control system and three emergency stop buttons for enhanced safety.
Center Control Table: Moveable layout showing rotation speed, feeding and lifting speed, and hydraulic system pressure.
Advanced Hydraulics: Adopts variable displacement pump, electric controlling proportion valves, and multi-circuit valves.
Steel Crawler Drive: Powered by a hydraulic motor, giving the rig wide maneuverability across rough terrains.
