54m Deep Rotary Drilling Rig with 320kN.m Torque and 2500mm Drilling Diameter for Bored Pile Construction

The 54m Deep Rotary Drilling Rig is a heavy-duty hydraulic drilling machine developed for deep pile foundation construction. Combining advanced hydraulic technology with a powerful CAT engine, the KR300C provides superior drilling performance for infrastructure, bridge, and commercial construction projects. The machine is engineered to deliver high productivity and reliable operation in difficult geological conditions.

The KR300C piling machine offers a maximum drilling depth of 54 meters and a maximum drilling diameter of 2500mm. The 320kN.m rotary torque allows efficient penetration through hard rock and compact soil layers.

• High drilling efficiency
• Large diameter drilling capability
• Stable hydraulic crowd system
• Heavy-duty winch performance
• Reinforced mast structure
• Smooth and reliable operation

The drilling rig is powered by a CAT C9 diesel engine with 259kW rated power output. The engine delivers strong power performance and excellent fuel efficiency, supporting long working hours on construction sites.

To ensure reliable operation, the KR300C adopts imported hydraulic components including:

• KAWASAKI pumps
• KAWASAKI valves
• REXROTH gearbox reducers
• Imported hydraulic hose systems

These components improve hydraulic efficiency and reduce machine failure rates.

• Deep bored pile construction
• Bridge and highway projects
• Railway and subway foundations
• Industrial construction
• Commercial building foundations
• Port and marine engineering
