Worlds largest hammer breaks through at bauma
The 865mm hammer can install casings 1.22m to 4.57m in diameter in drainage culvert and wash-over applications and can be used for pipe assist or pipe extraction, guided pilot bore ramming, and horizontal directional drilling assist.
The hammer was recently field-proven in an Ontario, Canada, wash-over casing job where it successfully installed 56m of 1.83m-diameter steel casing.
HammerHead CEO and president Brian Metcalf said, “We are excited to offer this extraordinary new product to our customers. Our new solid body 34inch [865mm] hammer enables us to provide solutions to the most challenging of projects on contractors’ job sites worldwide. The amount of power generated through our unique design and patented air reverse, that allows for forward and reverse from the control station, will provide contractors with productivity never before available for installation of large diameter pipe.”
Metcalf continued: “The release of the world’s largest pneumatic hammer cements our position as the leading manufacturer of pipe ramming and pipe bursting products available in the trenchless market today for the installation of underground utilities.”
The 865mm rammer has already been released for production, and 1.22m collets are available. Ram adapter cones are currently in development for other sizes, ranging from 1.22m through to 4.57m.
Although the hammer is designed specifically for pipe ramming projects, with custom-built tooling it can also be used for pipe bursting to replace 915mm pipe and larger. HammerHead will provide custom-built accessories upon request.
