Specifications
HF-44T wireline coring drill rig is wireline type, using Deutz diesel engine for power. It can be angel drilling with PQ tools.45~90 degrees HF-44T Hydraulic Wireline Core Drilling Rig
I. General
HF-44T Core Drill, a new type of product with enhanced capacity, is a kind of hydraulic-driven, spindle, diamond-bit, small-diameter core drill with fairly powerful drilling force. It is mainly suitable for exploration of metal or non-metal solid 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 foundation pile construction in large diameter. It is in reasonable structure, light weight, powerful capacity, multiuse, steady performance, high responsibility and high standardization and generalization.
