Detail: SM-300 Hydraulic crawler drills
SM-300 Rig is crawler Mounted with Top Hydraulic Drive rig .It is the new style rig our company designed and produced. 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.
1.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 cylinders driving and chain transmission. It have the long feeding distance and giving the convenient for the drilling
( 3) The V style orbit in the mast can sure the enough rigidity between the top hydraulic head and the mast and give 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) Rotation unit driving system is controlled by the Variable Flux Pump .it has the high efficiency.
( 7) Steel Crawlers drive by the hydraulic motor, so the rig has a wide maneuverability
( 8) the mast can turn 360oin horizontal direction, 90o/ -20o in vertical direction. The height can be adjusted at 2500.it can drill hole in any orientations.
( 9) The rig hydraulic system control by the proportion valve and the circuit.

Multifunctional Drilling Rig
All the functions of the rig will be carried out by hydraulic system, but controlled by electrical system. This drilling rig has a wide range of application, suitable for tunneling, metro, foundations and so on.
1. Main Features
( 1) Compact size of this machine, suitable for working in limited space.
( 2) The mast of this machine can turn 360 in horizontal direction, 120/ -20in vertical direction. The height can be adjusted at 2650 mm. MEDIAN can drill hole in any orientation.
( 3) The translation of mast can reach 3600 mm, so there is high efficiency.
( 4) Electric controller make the control of this machine just like playing game, very easy and legerity.
( 5) The functions include translation and rotation of the pivot, tilting angle adjusting of the mast, reposition of the drilling hole, pull down pressure adjusting, pull up speed adjusting, rotation speed adjust of rotation head etc.
( 6) The engine is powerful, suitable for wide range of engineering construction.
