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).
