Impact wrench DHW MAX

DOA DHW 9512 / DHW 17012 - hydraulic impact wrench for extremely stressed connections

DOA DHW 9512 and DOA DHW 17012 are a powerful range of hydraulic impact wrenches designed for the toughest industrial, construction and service applications. They are designed for loosening and tightening large bolted joints where conventional electric or pneumatic tools are not sufficient.

Thanks to their hydraulic drive, they deliver high torque without the need for a compressed air supply. This is a major advantage in cold environments, in the field, on construction sites, in mines, in oil & gas operations or in the maintenance of railway infrastructure. Both models are also available in an underwater version for professional diving and installation work underwater.

Main advantages

• Extreme torque: up to 9500 Nm on the DHW 9512 and up to 17,000 Nm on the DHW 17012.
• 11" square: robust clamping for large sockets and heavy industrial connections.
• Adjustable torque control: suitable for working with highly stressed bolts and nuts.
• 3-part impact mechanism: a reliable solution for heavy duty and long term work.
• Hand switching direction of rotation: quick alternation between loosening and tightening.
• Heat dissipating motor cover: increased durability under heavy use.
• Ergal handle: lightweight, strong and durable construction suitable for harsh environments.
• Ergonomic handle with integrated oil flow: better maneuverability and safer operation.
• Mechanical lever with safety lock: reduces the risk of accidental lowering.
• Underwater version available: suitable for underwater installation, shipyards and professional diver work.

Appropriate use
