25m portable DTH drilling rigs, hydraulic drilling machine KG910A     Advantage of KG910B DTH drilling rigs
1. Adopt famous 2-cylinder diesel engine as driving force which has advantages of large power, powerful grade-ability, small vibration and reliable operation.
2. Boom is adjustable. The angle of drilling hole and height of horizontal hole can be adjusted by controlling the stretch-out and draw-back of the hydro-cylinder. That enlarges the drilling hole’s range and improve the machine’s adaptability.
3. Oil supplied by two independent gear pumps, reliable operation, strong adaptability, easy maintenance. 4. Adopt gear transmission and soft connection, possessing compact structure and stable operation.
