Hydraulic Impact Top Drive Crawler Drilling Rig YGL-C200

Application
YGL-C200 Hydraulic crawler drilling rig can be applied to tunnel pipe-shed support drilling, grouting drilling, geothermal heat pump drilling, small foundation pile drilling, hydrologic well drilling, and blasthole drilling.
With the protection of hydraulic impact top drive casing, the rig can work in various ground conditions, such as on the unconsolidated formation, gravel layer, sand gravel, stone soil, detritus layer.

Features
1. It works very well on unconsolidated formation, gravel layer, fractured formation, silt and sand, and can from the borehole easily.
2. Drilling process can be carried out at speeds several times exceeding that of traditional ones.
3. It adopts the power head imported from Germany Krupp, which features multi-angle and multi-directional drilling with a good performance.
4. An air compressor is unnecessary because there is no dust pollution when it drills into the layer of rocks, gravel or stone soil.
5. Equipped with special casing drilling technique, the rig can finish the pipe-shed　 drilling quickly.
6. In complex formation, it can also perform double-pipe impact rotary drilling (single pipe + casing) and maintain the stability of the wall of the hole, facilitating the placement of grouting pipe and anchor cable.
