LD2500 LDD By Design

The LD2500 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.

  • 2500mm with under-reaming capability
  • Max drilling diameter 2500mm in standard configuration
  • Max power swivel torque 119kNm
  • Drill speed 0—60 rpm variable
  • Max drill string weight 50t
  • Max pull back 65t

The LD2500 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 incline)

The drill can be mobilised anywhere in the world as it can be broken down into component form, loaded into sea freight containers and reassembled on arrival. Typical assembly and re-commissioning takes 3-5 days.
