Herb Brumder bought Hydraulic Tool Co. in 1927, moved the Los Angeles company’s production to Milwaukee and began selling its jacks under his company’s Blackhawk brand. Two years before Blackhawk Manufacturing become Applied Power Industries, the company began selling its industrial hydraulic tools and systems under the Enerpac brand. Applied Power eventually rebranded as Actuant in 2000. Having transitioned from a diversified company to one focused on industrial tools, Actuant changed its name in September to Enerpac Tool Group, putting its industrial brand front and center.
