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 Dawson excavator mounted vibrators have been designed specically 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 ‘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 sufcient 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!
