HCR-8 Full Hydraulic Core Drilling Rig
I. General Introduction
HCR-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. It is suitable to use 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, etc. It is wire-line coring, and at the same time has the unique top drive function. The maximum torque is 7200 N.m(5307 lbfft), which will be much more suitable for large dia. drilling in coal bed methane, hydrology and water well. According to many years of experience in HDD field, our engineers install clamp and shackle device on the rig to relieve labour intensity, improve drilling efficiency and guarantee operator's safety.
HCR-8 is excellent in performance, high in working efficiency, easy for operation and keep the operators from dangers.
II. Main Performance Parameters of HCR-8
The figures in these tables have been calculated, based on field experiences, and may be reasonably expected.
Actual drilling capacity will depend on in-hold tools and conditions, drilling techniques and equipment used.
