DF-Y-5TL Core Drilling Rig
1.Use diamond bit or tungsten-carbide tipped bit
2.wire line coring, BQ/NQ/HQ
3.Diamond Core Exploration Drilling Rig
4.1800m
DescriptionParameter
1. There are more speed grade (8 grades), reasonable speed range, with low speed but high torque. The rig is adapted  for core  drilling  with  tongalley-carbid-tipped   and  diamond  bit, as well as  suitable  for engineering geological exploration, hydrological well drilling and basic pile engineering.
2. With large spindle  I.D. 93mm  (3.66 inch), the rig is fed with hydraulic  double cylinders  with much longer stroke up to 500mm(19.69 inch).With strong technological adaptability, the rig can be adapted on many field, especially on large diameter drill rod drilling, with wire line coring (upper part coring). Thus it is more effective in improving drilling efficiency with less faulty in hole.
3. With powerful drilling capacity, the rated drilling depth comes up to 1,300m(4,264 feet) with 71mm(2.80inch) drill rod with wire line coring.
4. Light in weight, the rig can be dismantled into 10 parts easily (the biggest one 450kg equivalent to 992 lb). The rig weighs 3,100 kg(6836 lb) (without power unit). It can be moved easily especially in mountain area.
5. The  hydraulic  chuck  adopts  one-way  oil  supply  and  equipped  with  hydraulic  lock.  The  chuck  is powerful and stable in clamping.
6. Equipped with water brake, the rig is steady and secure in deep hole drilling.
7. Supplying oil with a single-gear pump, it is easy for installation and application; lower in consumption of energy and a low temperature of hydraulic system oil; the rig is for sure in steady drilling. The hand oil pump may be used to hoist the drilling tools in hole upon the faulty of power engine.
8. Compact in structure and reasonable layout, and all exposed outside, non overlapped components, it is easier for maintenance and repair.
9. Low center of gravity and long travelling  distance up to 460mm (18.11 inch), the rig is reliable and stable in high speed drilling.
