Sanding Systems

Sanding systems are used in rail vehicles to improve friction between wheel and track. Operation is either automatic or can be initiated by the driver, who can use it in a targeted way for starting-up and braking.

Sanding system

During emergency braking, sanding is automatically activated. The sand is contained in a sandbox and, when necessary, is conveyed by compressed air between the wheels and the track.

Advantages:

  • Optional 2 stage or continuous speed dependent sanding
  • Complete pre-assembled sandboxes: Plug & Play
  • Compact design
  • Economical life-cycle costs

Knorr-Bremse, as a competent partner, offers all the components for a sanding system:

Air Supply

This comes from the vehicle air supply or from a dedicated, small electric compressor.

Sanding Unit

Sanding units work with the overpressure or/and underpressure principle. In addition to the sanding function, some sanding units also offer a heating function (for the entire sand box content) and a so called "after-blow" function.

Sand Pipe Heaters

Prevent freezing and blocking of the sand pipe.

Sand Level Indicator

Sand level can be checked either with a gauge glass or electronically with a filling level sensor.

Sand Box

As Knorr-Bremse is a systems supplier, sand boxes can also be supplied according to the customer’s own specifications.

Sand Box Cover

Sand box covers for manual filling or by means of a sand gun.
