ePRAX MAX -the complete system

  • "HOERBIGER ePrAX - THE eDrive Revolution"

Electric Drive featuring the Power of Hydraulics

  • Plug and work – compact and tubeless
  • Precise – 5 μm positioning accuracy
  • Fast – up to 230 mm/sec

The new HOERBIGER ePrAX drive blends electric and hydraulic systems in an entirely new concept. The electrohydraulic system eliminates the essential problems of both drive concepts and instead relies on the combination of their strengths.

In contrast to a strictly electric drive, the HOERBIGER ePrAX is powerful and durable, thanks to hydraulics. Because of its compact, closed design, its operation is clean and free of leaks, featuring no oil lines. The customer simply uses a few cables and eight bolts to attach the closed system to the frame of the press brake, like an electric drive. The smart electrohydraulic system operates with oil that the user does not see - yet it is strong, fast, environmentally friendly, energy-efficient and economical.

Thanks to the closed remote drive units, the customary complexity involving piping and a central oil supply system has been eliminated. Previously, a 250-liter central oil tank was required.

Together with the permanent lubrication and due to the compact, closed design, the maintenance interval is extended to more than three years.
