YHJ1200 Coal mine intrinsically safe laser orientation equipment
YHJ1200 coal mine intrinsically safe laser orientation instrument adopts semiconductor laser as a light source, with low power consumption, good beam quality, small size, light weight, easy installation and use, and stable and reliable performance. The DXH10/3.7 mining intrinsically safe power box and KDY127/5 encapsulated and intrinsically safe power supply can provide power for the orientation instrument.
The orientation instrument is widely used for directional positioning during mining tunnel excavation; guidance and control of the advancement direction of the road header; positioning of fully-mechanized mining faces in coal mines, as well as positioning and alignment of highways, railways, tunnels, culverts, bridges, high-rise buildings, and pipeline installations.
