Super quality! HF-8 Full hydraulic core drilling rig, geological drill rig
HF-8 full hydraulic drilling rig 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 7200N·m(5307 lbf·ft), which will be much more suitable for large dia. drilling in coal bed methane, hydrology and water well.
II. Main Performance Parameters of HF-8 full hydraulic drilling rig
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.
