Core Drilling Rig XY-44A
Core Drilling Rig XY-44A
XY-44A core drill is core drilling equipment based on diamond and hard alloy, mainly used in metallurgy, coal, geology, hydrology, engineering and other industries, also can be used in engineering geological exploration, shallow oil and gas mining, mine tunnel ventilation, water well drilling, large diameter pile foundation engineering construction.
The main features of XY-44A type drilling rig
1, The rig has more speed series (grade 12 to 2 positive inversion) and reasonable speed range, low-speed torque (up to 8000N.m), which is suitable for alloy, diamond core drilling, also suitable for engineering geological investigation.
2, vertical through-hole diameter (93mm), double cylinder hydraulic feeding, long stroke (up to 600mm), strong adaptability, suitable for large diameter drill rope core (upper core drilling), is conducive to improve the drilling efficiency.
3, Hydraulic chuck clamping disc shaped spring, hydraulic release, three slip type hydraulic automatic centering.
4,The hydraulic system adopts gear oil pump, simple installation, convenient use, less power consumption, low oil temperature in hydraulic system, stable work. System equipped with hand pump, when the engine does not work when the hand pump is still available from the drill hole.
5,rig low center of gravity, moving long distance (460mm), stable fixation, high speed drilling stability.
6, with a vibration meter, to grasp the hole. Hand manipulation, flexible manipulation
