Hydropower JK410 Crawler Mounted Pneumatic Tophammer Drill Rig Multi-Angle Anchor Hole Boring

The Hydropower JK410 crawler mounted pneumatic tophammer drill rig is engineered for the demanding anchor hole and drainage hole works found on dam construction sites. It was specially designed for hydropower projects where boreholes must be drilled at many different angles, from flat horizontal anchors to steeply inclined curtain holes. The pneumatic top hammer provides clean, straight holes in the fractured rock typical of river valley abutments, while the crawler base allows the machine to be repositioned quickly between working faces. With its compact envelope and 6-ton weight, the rig can be transported through access tunnels and narrow construction roads without special permits.

• Full Angle Coverage: Drills boreholes from horizontal to vertical, covering anchor, grout and drainage hole layouts in one setup.
• Stable Crawler Platform: The wide track base and 20-degree grade ability keep the feed aligned on steep abutment slopes.
• Consistent Hole Quality: A rigid feed beam and T38 rod string produce straight holes that meet anchor installation tolerances.
• Wet Drilling Option: A 0.4 MPa water system can be connected for wet drilling, reducing dust in confined valley works.
• Quick Repositioning: Self-propelled travel at 2 km/h shortens move time between anchor rows on long dam faces.
• Low Noise Operation: The pneumatic drifter runs with moderate noise levels, suitable for sites close to existing structures.

This machine is applied on hydropower dam abutments, powerhouse foundations, penstock anchor walls and slope stabilization works. Typical tasks include tension anchor holes, consolidation grout holes, curtain drainage holes and rock bolt drilling in underground chambers. The rig also suits bridge abutment anchoring and tunnel portal support work where multi-angle drilling is required.

The drilling rig is packed in export seaworthy condition and shipped by 40ft flat rack container or RORO vessel. A pre-delivery test report, operation manual and spare parts list are supplied with each unit. Our service team supports commissioning, operator training and remote troubleshooting for projects worldwide.
