The LD612 is a reverse circulation drilling rig capable of drilling through almost any soil and rock type. This enables the creation of sockets of up to 2000mm dia. In its standard configurations and with the addition of a cellar deck, sockets up to 3000mm with under-reaming.
The drill is comprised of 4 main sections: Drill gripper, Drill base, Mast and carriage and Power Swivel. The gripper allows connection to the pre-installed pile 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 which is interchangeable with the LD2500. Thrust is provided by the two carriage rams located in the drill mast supporting the carriage.
Down-hole under-reaming can be used in a variety of applications to enhance installation efficiency and pile capacity and sockets can be drilled from vertical to 18° (1:3 rake).
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 upon arrival. Typically re-commissioning takes 2-3 days.
The LD612 is powered by a diesel hydraulic unit connected via a 30m supply umbilical.
