EXCAVATOR MOUNTED
OR CRANE SUSPENDED
VIBRATORS
Driving / extracting when the movement is less than 1”
(25mm) per minute is considered pratical refusal. Driving
/ extracting when movement is less than 1” (25mm) for
more than 5 minutes of driving / extracting or driving at
all when penetration is less than 1” (25mm) per minute
and amplitude is greater than 1” (25mm) [ vibrator and
pile are bouncing] is considered improper use and will
void the warranty. Contact DCP for an alternative larger
vibrator.
Principal Advantages
. Compact, robust and reliable - no electrics!
. Simple and fast attachment to excavator
. Minimal height to maximise pile length
. Slim design to drive single sheet piles
. High power to weight ratio
. Universal joint suspension for easy alignment of piles
. Extremely low vibration transmitted to the excavator
. Enviromentally friendly - low noise/localised
directional vibration
. Automatic hydraulic clamp operation
. Flexiblity in application
. Flow regulator prevents excessive oil supply to vibrator
. Heavy saddles available for crane suspended models
Dawson excavator mounted vibrators have been designed
speci
fi cally to work in place of an excavator bucket to drive and
extract piles. The pile can be lifted to vertical using the built-in
lifting chain where it is then gripped tightly in a powerful hydraulic
jaw. Once secured, the pile is then vibrated with high frequency
vibrations so as to ‘
fl uidise’ the soil resisting the pile. Down-crowd
force applied by the excavator boom, coupled with the self-weight
of the pile and the vibrator, provides suf
fi cient force to push the pile
into the ground.
Naturally, the process works in reverse for pile extraction. The
equipment offers a highly productive and cost effective piling rig
based around a standard, readily available excavator!
