The LD2500 is a reverse circulation

drilling rig capable of drilling through

almost any soil and rock type. The rig

can accommodate drill bits of up to

5000mm with the BHA hanger

assembly.

The LD2500 has two power swivel op-

tions: a). 119kNm of torque operating

at max 34 RPM; or b). 539kNm of

torque operating at max 3 RPM.

The gripper allows connection of the

drilling rig to the pre-installed pile or

conductor with sufficient capacity to

accommodate the static and dynamic

forces the drill rig can generate. The

drilling rig may also be installed on a

cantilevered frame on a JUB.

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 rake).
