Introduction to Crawler Mounted Drill Rig
Geological
Core Sample Drilling Rig / Small Bore Well Drilling Rig is a new type
of vertical spindle machine manufactured by Glorytek Industry which a
diesel engine or motor may be chosen as power. It is primarily used with
diamond drill bit or carbide drill bit for the
drilling in solid mineral deposit as well as those in engineering geotectonic survey, foundation pile hole and water well hole.

The rig has the following characteristics
1. A reasonable range of rotation speed is selected. The rotation speed
is divided into eight stages, with centralized speed change and mutual
self-locking. It is suitable for drilling rig sampling and pile hole
construction.
2. The rig has two reverse speeds, which is convenient to handle faults safely.
3. The rotary chuck adopts the manual ball chuck, which is reliable in
clamping, does not damage the active drill pipe, and can reverse the rod
without stopping.
4. Oil pressure feeding, easy operation, high drilling efficiency and low labor intensity.
5. The control handle is less, the layout is reasonable, and the operation is flexible and reliable.
6. The double disc normally closed friction clutch is adopted, which is
flexible in opening and closing, and easy to adjust and use. Equipped
with fore-and-aft moving oil cylinder, the rotator moves 465mm backward,
which brings a lot of convenience to the following drilling tools.
7. The drilling rig is light in weight, compact in structure and
convenient in assembly and disassembly. It is suitable for drilling in
hilly or
mountainous areas.
1. Compact mechanical transmission structure, lightweight, vertical spindle for large through hole diameter with hexagonal drive
drilling rod, ensured torque transmission.
2. Higher rotating speed and rational scope, adaptable for the
drillings with small diameter diamond drill bit or large diameter
carbide drill bit and other engineering hole drillings.
3. During the hydraulic controlled feeding process, both the pressure and speed of feeding can be regulated to meet the
requirements of different stratum drillings.
4. Less and centralized handles, easy operation.
