Applications

The ST 260 drilling rig is engineered for complex geological conditions including rock, mud, and sand formations. Its versatile design supports multiple drilling methods including top drive hydraulic rotary, DTH drilling, and mud pump drilling operations.

Operational Guidelines

1. Always clean the hole bottom and remove residue before changing drilling tools. Lift tools gradually when the force is optimal.

2. Monitor casing follow-up and hole conditions continuously during operation. Never force the drill bit during extraction.

3. For rock slag accumulation, apply air pressure to clean the hole before reactivating the DTH hammer and lifting the central drilling tool.
