Introduction:
GYQ-300A drilling rig is an upgraded and improved product of GXY-2 drilling rig. It mainly adds the winch detachment
function structure, thereby extending the service life of the hoist. This drilling rig is a vertical transmission rotary drilling
rig with mechanical transmission and hydraulic feed. It can be applied to engineering geological survey, general survey of
solid deposits, grouting of dams and ventilation and drainage of tunnels. Depending on the drilling formation, cemented
carbide, steel grit, and auger types can be used for drilling.
Main Feature:
The structure of this rig has the following features:
1. A more reasonable speed range is selected. There are eight speed levels, centralized speed change, self-locking with
each other, large low-speed torque, and a wide range of use.
2. The drilling rig has two speeds of reversing speed, which is convenient for handling faults safely.
3. The self-centering hydraulic chuck is adopted, which is convenient for clamping and loosening the drill pipe. And has
a hydraulic feed mechanism, strong pressure and lifting capacity.
4. Equipped with sufficient instruments, it is helpful to grasp the situation in the hole, fewer operating handles, more
reasonable layout, flexible and reliable operation.
5. The two-plate normally closed friction clutch is adopted, which is flexible to open and close, and easy to adjust and use.
6. The rig is light in weight, compact in structure, easy to disassemble, and suitable for drilling work in hills or mountains.
7. The hoist has a detachment function. Increased the service life of the hoist.
