Diesel Crawler Water Well Drilling Machine

Jining Bafang Mining Machinery Co.,Ltd is one of the leading diesel crawler water well drilling machine manufacturers and suppliers in China,Website:http://www.bafangjixiechang.com, welcome to buy cheap and low price diesel and electric crawler drilling rig made in China from our factory. JK590 Crawler  Hydraulic Quarry Blast Hole DTH Drilling Rig Advantages 1.Hydraulic DTH Drilling Rig  2.ISO9001 certificatied  3.Lower oil consumption  4.Direct Manufacuturer 5.Fast drilling speed and safe  operation JK590 Crawler Hydraulic Quarry Blast Hole DTH  Drilling Rig Product Description JK590 Crawler  Hydraulic DTH Drilling Rig is an upgraded product of CM358A crawler-type down-hole  drill,with more improved function and  more reliable performance. JK590  internal combustion(JK590D electric) Crawler Hydraulic DTH Drilling  Rig  is equipped with diesel engine (electromotor) ---- hydraulic oil  pump unit as its drive device, and achieves the supporting movements such as  rotation, propulsion, lifting, moving, pivotangle orientation of hydraulic oil  cylinder through hydraulic motor. When the JK590 is doing drilling works, only  DTH impacter will consume the compressed air. Compared with whole-pneumatic drilling rig, the air displacement of matched air compressor is reduced by 30%  to 50%, and the consumption of energy (fuel or electricity) is 40% to 50%  during operation.  The JK590 internal  combustion(JK590 Electric)is a crawler-type hydraulic down-hole drill, mainly  used in drilling and blasting task, such as water and electricity project,  open-cast mining, construction of roads and national defense project.  Product Features 1. Chassis. The  originally imported walking motor possesses high gradeability to drive the air  compressor. 2. Drive device. Yuchai  70KW turbocharge engine is featured by the strong power and easy maintenance. 3. Turn-around machine.  Large rotary torque, the unconsolidated layer is not easily sticking, high  pore-forming rate. 4. Control console.  Centralized control console provides convenient operational control of drilling  rig 5. Propulsion mechanism.  Double locked hydraulic machinery not just guaranteed the stable high torque  output of hydraulic motor, its service life also greatly extended. 6. Multi-angle  functional drilling arm is possessed with wide scope of the drilling angle. It is able to drill the horizontal hole, forward and backward dip angle hole as  well as the lateral dip angle hole.
