Hydraulic pile driving vibrator
DAWSON CONSTRUCTION PLANT LIMITED
designed specifically 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 'fluidise' 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 sufficient 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!
