About HammerHead Trenchless

HammerHead Trenchless began in Oconomowoc, Wisconsin. Jon Haas had an idea to make a better earth-piercing tool. Haas consulted his high school friend and Harley-Davidson® engineer, Rob Crane. Rob, in turn brought in his fellow engineer, Steve Wentworth and the three got to work designing what would become the HammerHead Mole® piercing tool. The namesake of what is now the industry’s most complete offering of trenchless solutions from a single source.

As the company grew, the design team set out to develop and improve other trenchless products. Such as pipe ramming tools, pipe bursting systems and purpose-built winches and rod-pulling machines. Each new design reflected the fundamental principles of HammerHead’s winning formula. A focus on quality, durability, ease-of-use, ease-of-maintenance and low cost of ownership.

In 2010, HammerHead Trenchless was acquired by Charles Machine Works. A family of Companies focused on innovative, customer-driven solutions for the installation, maintenance and rehabilitation of underground pipe and cable. Together, the Family of Companies makes up the Underground Authority offering the most advanced equipment and solutions for underground construction and service in the world today.

Today HammerHead Trenchless produces a comprehensive suite of trenchless equipment and consumables. For the installation, repair and replacement of fibre, communication, water, sewer and gas underground infrastructure.
