Spindle Type Core Drilling Rig (HXY-9B) with 4200m Drilling Capacity

I. General

HXY-9B is an improved product based on HXY-8B. It is mainly used in core drill with diamond bit or hard tungsten-carbide tipped 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's gallery ventilation and water discharge tunnel drilling as well as foundation pile construction in large diameter.
It is compact in construction, rational in overall arrangement, moderate in weight, convenient in assembling and suitable in the range of rotation speed. It is equipped with water brake, normal-open clutch mechanism and with high hoisting force as well as low-position operation.
