Crane Suspended Hydraulic Vibro Hammer

Dawson range of cranse suspended vibrators have been designedto work with Dawson Impact Hammer Power packs 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 self-weight of the pile and the vibrator heavy duty saddle,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, low weight to power ratio means smaller cost effective cranes can be utilised for inserting or extracting tubular, H, Z and U piles.
