A versatile rig for nearshore and offshore

The LD818 is a reverse circulation drilling rig capable of drilling through almost any soil and rock type. The rig can accommodate standard LDD drill bits up to 2500mm with under-reaming options allowing the drilling of much larger holes.

Click here to download our LD818 spec sheet or feel free to contact our team for more information on its capabilities and how it suits your project requirements.

The LD818 is comprised of 4 main sections: Gripper, Drill base, Mast and carriage, and Power Swivel. The gripper allows connection to the pre-installed pile or conductor with sufficient capacity to accommodate the static and dynamic forces the drill rig can generate.

The Power Swivel provides the rotation force required to drill the socket. Thrust and holdback is provided by the carriage rams located in the drill mast supporting the carriage.

Down-hole under-reaming can be used in a variety of applications to enhance installations efficiency and pile capacity and sockets can be drilled from vertical to 18° (1:3 inclination)
