Unwin Super Kitten Rig
These fully hydraulic, purpose built piling rigs
are designed and built for the installation of
Continuous Flight Auger Bored Piles to a
maximum diameter 300mm and Open Auger
Bored Piles, using both temporary and
permanent casing, up to a maximum diameter
of 220mm, bored by a mast mounted rotary
head delivering a torque of up to 5,000Nm.
The diameter of Open Auger Bored Piles can be
increased to 400mm in certain cases by slight
workshop modification. The rig is also capable
of drilling using both the Duplex and Odex
techniques and also drilling through
obstructions and hard ground with Down The
Hole Hammer (DTHH) equipment. The
The
hydraulic mast can be extended / retracted to
permit piles to be installed in very limited
headroom. The rig is powered by a hydraulic
power pack that is towed behind the rig, but
can be located up to 50m from the rig during
pile installation. The retractable rubber tracks
and fully raking mast ensure that the rig can be
tracked through a standard doorway to a
working area.
