The XY-44A drilling rig is a mid- to long-hole core drilling rig with complete functions and stable performance, which is modified and designed based on the XY-44. It is not only suitable for large and small diameter core drilling with alloy and diamond as the main materials, but also can be used for engineering geological survey and engineering construction in the fields of construction engineering, hydropower engineering, highway, railway, port, etc. The machine has reasonable structure, light weight, large capacity, standardization and high degree of generalization.

The drilling rig has the following features:

1. It adopts automobile gearbox and clutch, with compact and reasonable structure, stable operation, low noise, high transmission efficiency and easy assembly and disassembly.

2. It has a reasonable speed range and multiple speed levels, large low-speed torque and a wide range of use.

3. Equipped with water brake, deep hole drilling, smooth and safe drilling.

4. It has two reverse speeds to facilitate accident handling in the hole.

5. The drilling rig has high power.

6. Advanced structure, reasonable layout, easy to repair and maintain.

7. Small size, light weight and good detachability.

8. The drilling rig vertical shaft has a long feed stroke, which is beneficial to improving drilling efficiency and reducing the occurrence of accidents such as drill blockage and drill burning.

9. The vehicle can be moved smoothly, fixed simply and reliably, and the high-speed drilling has good stability.

10. The drilling rig has few operating handles, reasonable layout, and flexible and reliable operation.

11. The drilling chuck adopts hydraulic pin type, which can clamp reliably and will not damage the active drill rod.
