Customer challenge

A vehicle or mobile machine manufacturer is required to provide a mechanical / hydraulic power-take-off (mPTO/hPTO) for an electrically operated vehicle (eTruck) or mobile machine (e.g. eTractor) or a body builder / implement manufacturer is required to convert a defined electrical HV-interface (ePTO) to a mechanical (speed, torque) or hydraulic (pressure, flow) interface for the operation of superstructures (attachments / auxiliary functions).

System description

The Kinell emPTO / ehPTO System offers a validated and easy-to-integrate electrically operated mechanical or hydraulic PTO solution for defined HV interfaces (ePTO). It includes:

  • Validated mobile inverter / e-drive combination
  • Mechanically compatible hydraulic pump (optionally)
  • emPTO control unit for dedicated emPTO control with flexible communication interface to E-body / E-implement
  • Mercedes eEconic/eActro and MAN eTGS / eTGX ePTO compatibility (HV & control)
  • Cooling circuit with pump and fan (optional for autarkic colign system)
  • LV wiring harness with the communication interfaces to the vehicle chassis and body / implement
  • HV cabling with an automotive plug for ePTO connection.
