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 braki
