Wire-Line Main Drilling Rig (HF-44A)
I. CZPT
HF-44A Core Drill, a new type of product with improved capacity, is a kind of hydraulic-pushed, spindle, diamond-little bit, small-diameter main drill with relatively potent drilling force. It is largely suitable for exploration of steel or non-metal strong mineral ore bed. It is widely applied in core drill with diamond bit or hard tungsten-carbide-tipped bit and diamond bit in the field of geology, metallurgy, coal mine, hydrological and engineering drilling. It can also be used in the fields of superficial-zone
petroleum and natural gas mining, mine workings ventilation and water discharge tunnel drilling as well as basis pile construction in large diameter. It is in reasonable structure, light weight, powerful capacity, multiuse, continual performance, large responsibility and substantial CZPTization and generalization.
