Customized high-power engine with dual drive power head and large output torque, which can meet the requirements of complex formation construction and high construction efficiency.

Roller Bit

The single roler bit is composed of a single cone and a lug matched by a bearing.According to different strata and construction requirements, different cutting struclures can be selected; wear resistant carbide are welded and cemented carbide inserts are inserted on the back of the lug. Rotary drilling rig drives the shaft to rotate and exert positive pressure so that the rotary dril- ing bit can impact, roll and shear the rock. Crush the rock to form a crushing ring zone.Then break the middle pillar by the swing of the shaft and take the broken pillar out to form a hole.

KR240M DSM Rotary Drilling Rig

Deep Soil Mixing (DSM) rigs use rotating shafts with cutting tools to blend soil with binders, creating stronger ground.

Product Detail

Product Advantages

All-Round, Multi-Angle Construction Capability

Supports vertical, horizontal, and inclined operations; adapts to small-section tunnels/coal mine roadways, meets drilling/water stopping/drainage/grouting needs, and enhances narrow-space adaptability.

Modular Power Head & Mast Design

Comes with replaceable modules; switches per geological conditions/construction goals for “one machine, multiple uses,” cutting equipment costs and boosting efficiency.

Diesel-Driven Power System

Diesel engine as core power source; ensures stable high-torque output in power-limited mines/ tunnels, balances fuel efficiency for long continuous operations.

Load-Sensing Hydraulic System

Adopts load-sensing control; adjusts pressure/flow in real time to avoid energy waste, reduces oil temperature, extends component life, and meets green construction requirements.
