John Josslin with DBM Contractors has been contracted by Quigg Brothers Construction to install 9′ diameter permanent casing for a bridge over the Wickshaw River.

John chose the Largest single gearbox driver/extractor in the world with the APE Quad Clamp System because the specified casing thickness was light and the three foot minimum penetration in the sandstone for the tip elevation was required and if the SuperKong couldn’t do it- nothing could.

Once the casing was driven to the sandstone it took 15 minutes at a lower frequency to hammer the casing to tip. For more information on the Quad Clamp System call the APE Kent, WA Factory.
