Main Features
(1) With a large number of rotation speed series (8) and appropriate range of rotation speed, low speed with high torque. The drill is suitable for alloy core drilling and diamond core drilling, as well as engineering geological exploration, water well and foundation hole drilling.
(2) This drill is with big spindle inner diameter(Ф93mm), double hydraulic cylinder for feeding, long stroke (up to 600 mm), and strong process adaptability, which is very suitable for wire-line coring drilling of large diameter drill pipe, and is helpful to improve drilling efficiency and reduce hole accident.
(3) This drill has large drilling capacity, and the max rate drilling depth of Ф71mm wire-line drill rod can reach 1000 meters.
(4) It is light in weight , and can be assembled and disassembled conveniently. The drill has a net weight of 2300 kilogram, and the main machine can be disassembled into 10 components, which make it to be flexible in movement and suitable for mountain work.
(5) The hydraulic chuck adopts one-way oil supply, Spring clamp, hydraulic release, chuck clamping force, clamping stability
(6) Equipped with water brake, the rig can be used for deep hole drilling, smooth and safe under drilling.
(7) This drill adopts single gear oil pump to supply oil. Its virtues are installation simple, eay to use, low consumption of power, low oil temperature of hydraulic system and stable working. The system is equipped with hand oil pump, so we can still use the hand oil pump to take out the drilling tools even the engine can not work.
(8) This drill is compact in structure, rational in overall arrangement, easy maintenance and repair.
(9) The drill has a low center of gravity, long skid stroke, and is fixed firmly, which bring good stability with high speed drilling.
(10)Equipped with shockproof instrument, and the instrument has long life, which can help us grasp the hole situation. Less control lever make the operation flexible and reliable.
