Description
Rock-Socketed Rotary Piling Rig 400 kN.m Torque 2800 mm Diameter for Bridge Pier Foundation Piles
The RKR-400 rock-socketed rotary piling rig is a heavy-duty foundation drilling machine built for the most demanding large-diameter piles. With a rated output torque of 400 kN.m, a maximum drilling diameter of 2800 mm and a maximum depth of 90 m, it is engineered to socket piles deep into strong rock for bridge piers, port structures, high-rise towers and major infrastructure foundations.
Powered by a 403 kW EU Stage V engine and a high-pressure hydraulic system, the rig combines a 300 kN crowd force with a five-section interlocking kelly bar to transmit maximum torque to the rock drilling tool. When hard rock is encountered, the machine switches to a down-the-hole hammer or rock auger, maintaining fast penetration even in granite and limestone. A reinforced 125 t carrier and heavy-duty undercarriage keep the rig rock-steady during the highest torque operations.
Key Features
  • Deep Rock Socketing: A 400 kN.m rated output torque and a 300 kN crowd force drive rock augers and DTH hammers deep into hard granite and limestone.
  • Large 2800 mm Diameter: A maximum drilling diameter of 2800 mm supports the massive foundation piles required for bridge piers and port structures.
  • 90 m Drilling Depth: A maximum drilling depth of 90 m with a five-section interlocking kelly bar handles the deepest bored piles in major infrastructure works.
  • Heavy-Duty Power: The 403 kW EU Stage V engine supplies abundant power for sustained torque, crowd and winch demand on long pile cycles.
  • Multi-Tool Capability: The rig accepts rock augers, drilling buckets, DTH hammers and core barrels, adapting quickly to changing ground conditions.
  • Reinforced 125 t Carrier: A heavy, wide undercarriage provides the stability and structural strength needed for the largest kelly bars and rock tools.

Applications
The rock-socketed piling rig is designed for large, deep and heavily loaded piles. It is used for bridge piers and abutments, port and marine structures, high-rise building foundations, wind turbine bases and other major infrastructure requiring piles socketed into rock.
Its ability to switch between soil tools and rock tools means a single machine can drill through overburden and continue into hard rock without a change of rig, reducing mobilisation and improving programme certainty on complex geological sites.
Packaging & Quality Assurance
Given its size, the rig is shipped by break bulk or on heavy flat racks, with the mast folded and all hydraulic and electrical connections protected. Kelly bars, rock augers, DTH hammers and wearing parts are packed separately in reinforced crates.
A 12-month warranty covers the main structure, power unit and hydraulic system. Full commissioning support, operator training, maintenance manuals and spare parts lists are provided, and our technical team offers remote diagnostics and on-site service for the lifetime of the machine.
