product Introduction
HFCR-8 full hydraulic core drilling rig is an efficient and multi-functional full hydraulic core drilling rig newly developed on the basis of the research and development, manufacturing and user feedback of the HFDX series of full hydraulic core drilling rigs.
Features
- 1HFCR-8 Hydraulic Core Drilling Rig, an up-to-date multifunctional product is a thoroughly new-type hydraulic core drilling rig developed on the basis of the market demand and the advanced techniques in the world.
- 2HFCR-8 is suitable to be used in plains, hills, high temperature as well as low temperature places. The main machine is integrated in structure, which consists of self-propelled chassis, power, mud pump and hoist. It is wire-line coring, and at the same time it has the unique top drive function.
- 3HFCR-8 is excellent in performance, high in working efficiency, easy for operation and it can efficiently keep the operators from danger.
Application
HFCR-8 is suitable for working in harsh environments such as plains, hilly areas, high temperature and severe cold. It is mainly suitable for metal and non-metal solid deposit exploration, coalbed methane, natural gas, hydrological water wells, geothermal wells, mine tunnels, ventilation and drainage holes and engineering emergency construction. It is widely used in geology, coal, metallurgy, non-ferrous, petroleum, hydrology, engineering and other industries, mainly diamond and cemented carbide drilling, and meets the requirements of multi-functional drilling such as rope coring and top drive drilling. One of the equipment.
