Prodiuction Description:
As a spindle type drilling rig, the XY-44A core drill rig takes diamond bit or tungsten-carbide -tipped bit is aligned with a water brake. It is fed with double cylinders that travel much longer. Its oil is supplied in two opposite directions by hydraulic spider disk with a hydraulic lock. It is widely used in engineering geology exploration, hydrology well drilling and basic pile engineering (core drilling, well drilling, pile drilling).
There is one thing worthy noticing. The core drill rig adopted new technology. The technology can be used in numerous models, particularly on large diameter drill pipe. This technology is quite effective to improve the drilling efficiency.
