Railway "Sand Filling System"
FACILITIES FOR LOADING NON-SLIP SAND FOR FREIGHT TRAINS:
The problem of rail slipping is eliminated by increasing the coefficient of friction between the wheel and rail, for which sand is used.
This sand is projected in front of the wheels in the direction of travel only at specific times for example when trains, trams or locomotives start or brake.
Slipping is normally produced by the presence of leaves on the rail, wet rails, slopes, etc. It is a problem that can affect the integrity of the traction motors (excessive force) or the infrastructure, because a wheel slipping on a steel rail may melt it.
NEWTEK has been manufacturing, assembling and maintaining facilities for this purpose since 1987. These comprise a Silo to store the sand that arrives by tanker or Big- bags of 1.000 Kg. approx. A pneumatic conveyor sends the sand to the pumps which load the sand boxes located in the driving bogies of the vehicle, a facility similar to that of a petrol station.
