SM-300 Full Hydraulic Core Drilling Rig

SM-300 Rig is crawler mounted with top hydraulic drive rig. It is the new style rig our company designed and produced.

1. Application Range

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.

2. Main Features

(1) Top hydraulic head driver is droved by two high speed hydraulic motor. It can supply the great torque and the wide range of the rotation speeds.

(2) Feeding and the lifting system adopt the hydraulic motor driving and chain transmission. It has the long feeding distance and giving the convenient for the drilling.

(3) The V style orbit in the mast cans sure the enough rigidity between the top hydraulic head and the mast and gives the stability at the high rotation speed.

(4) Rod unscrew system make the operation simply.

(5) Hydraulic winch for lifting have the better lifting stability and good braking ability.

(6) Electric controlling system has center control and the three emergency stop buttons.

(7) Main center control table can move as your wants. Show you the speed of the rotation, the feeding and lifting speed and the pressure of the hydraulic system.

(8) The rig hydraulic system adopt the variable pump, electric controlling proportion valves and multi-circuit valves.

(9) Steel crawler drive by the hydraulic motor, so the rig has a wide maneuverability.
