XY-44A Hydraulic Drilling Rig is a spindle rotary drill rig suitable for both diamond core drill and wire line core drilling as well as SPT. It is used for civil engineering projects, small diameter piling work, mineral exploration, geothermal utilization, water well drilling etc.

1. Rig has 8 gear shift and proper speed, 2 reverse speed for handling drilling accident.
2. Can be used for both small diameter diamond core drilling and large diameter alloy bit core drilling as well as other engineering project drilling.
3. Rig can travel 460mm on frame, enhance the convenience in drilling operation.
4. Long spindle travel, reduces the occurring of stalling and bit burnt and improves drilling efficiency.
5. Rig is firmly built, gravity center is at lower level, very stable and less vibration in high speed drilling.
6. Auto Vehicle gear box and clutch, higher power transmission efficiency, easy assembly.
7. Easy assembly and disassembly.
8. This rig has hydro retarder (hydraulic brake), drilling is more stable and safe.
