NPK's line of railway mining equipment is made up of two types of Paus rail driven machines: rail excavators, most commonly used for cleaning rail-side ditches, and rail mucking loaders, used for cleaning tracks.

The Paus KRF 40 Rail Excavator (Ditch Cleaning Vehicle) utilizes boom-mounted attachments to guarantee simple and fast cleaning of the rail bed, drains and ditches to the right and left of the tracks.  It quickly transfers debris directly onto a conveyor belt that loads the material into an attached truck.

  • Hydrostatic drive.
  • Spacious driver's cabin
  • Clearly arranged controls
  • Easily accessible maintenance points.

Options include:

  • Bucket for rail track cleaning.
  • Scraper.
  • Ripping hook.
  • Welding apparatus.
  • Hydraulic hammer.
  • Cabin equipped with heating.

The Paus KRF 40D & KRF 40E.1 Rail Mucking Loaders (Track Cleaning Vehicles) utilize a front-mounted bucket to scoop and transfer debris directly onto a conveyor belt that loads the material into an attached truck.  Choose from the Paus KRF 40D that is driven by a powerful diesel engine and the KRF 40E.1 that is powered by a direct-current electric motor.

  • Hydrostatic drive.
  • Spacious driver's cabin.
  • Clearly arranged controls.
