Main Features Of Rig Mounted Core Drill
1. With a large numbers of speed series (level 8) and a reasonable speed range, low speed torque is large (up to 6000 nm), which is not only suitable for alloy and diamond core drilling, but also suitable for engineering geological survey and water exploration.
2. Large diameter (96 mm diameter) of through hole of vertical shaft, hydraulic feed of double oil cylinder, long stroke (600mm), and strong adaptability of process, especially suitable for drilling of large diameter drill pipe rope (upper core).
3. XY-6 is a core drilling rig for deep hole. With powerful drilling capacity, the rated drilling depth comes up to 1,600m with wire line 71mm drill rod.
4. Good dismountability, the net weight of drill rig is 3800 dry grams, and the main engine can be decomposed into 10 parts, which is convenient for relocation and suitable for working in mountainous areas.
5. Water brake, deep hole drilling, smooth and safe drilling.
6. Supplying oil with a simplex gear pump, it is easy for installation and operation; The hand-operated oil pump can be put in use to hoist the drilling tools in hole upon the power engine failing to operate.
7. The mechanical drilling rig is compact in structure and reasonable in layout. All components are exposed and do not overlap each other, which is convenient for maintenance, maintenance and repair.
8. Low center of gravity, long moving distance (up to 550 mm), stable and reliable.
9. It is equipped with an anti-vibration instrument with a long life, which is conducive to mastering the condition of the hole, with less handle and flexible and reliable operation.
