Mountain JK930 Hydraulic Tophammer Drill Rig Cummins QSC8.3 Engine 194KW Folding Boom

The Mountain JK930 hydraulic tophammer drill rig is built to keep drilling on steep and uneven terrain where standard rigs struggle. Its maintenance-free four-track walking system, designed specifically for construction machinery, provides a +/-10 degree body float angle so the machine can level itself continuously while moving and drilling on slopes. The 500 L fuel tank and 194 kW Cummins engine allow long autonomous working days in remote mountain sites. Combined with the 25 m automatic rod changing capacity, this rig delivers exceptional productivity for mountain road, tunnel approach and highland quarry projects.

• Four-Track Walking System: Maintenance-free tracks with +/-10 degree body float keep the rig level on steep slopes.
• Powerful Cummins Engine: The 194 kW QSC8.3 engine provides reliable power for drilling and tramming in remote areas.
• Large Fuel Capacity: A 500 L tank supports full shifts without refueling logistics in isolated sites.
• Automatic Rod Carousel: Seven T45/T51 rods enable 25 m one-time drilling with minimal operator handling.
• High Impact Drifter: The HC150 delivers 21 kW impact power with adjustable frequency for varied mountain rock.
• Efficient Air System: The three-stage air filtration and screw compressor keep flushing reliable in dusty conditions.

This rig is deployed on mountain highway construction, highland quarry development, tunnel portal excavation, wind farm access roads and slope treatment projects in difficult terrain. The four-track system and body float feature allow safe operation on 20-degree slopes, while the automatic rod changer keeps production high in remote locations where labor is scarce.

Machines are delivered with export seaworthy packing and shipped via 40ft flat rack container or RORO vessel. Factory testing covers the track system, rod carousel and drilling functions. Full documentation, remote commissioning support and a durable spare parts program are included with every unit.
