Product DescriptionHRC-8 Crawler Mounted Full Hydraulic Drilling
RigGeneral IntroductionHCR-8 Hydraulic Core Drilling Rig 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 Nm
(5307 lbf ft), 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 labor 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. Product
ParametersMain Performance Parameters of HCR-8The 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. Power UnitPower276 kW (370HP) at 2100
