DEVICE TO REMOVE ICE AND SNOW TRACKS FROM HARD ROAD COVERING Russian patent published in 2011 - IPC E01H5/12 

FIELD: transport.

SUBSTANCE: proposed device comprises elements to destruct road tracks made up of disks fitted on two axles with variable eccentricity and coupled at the angle of over 180° that may be varied depending upon track characteristics. Said disks may passively rotate from driving force and forces of friction between disk edges and track surface. Frequency of angular velocity and amplitude of vertical oscillations of disks are defined by disk diametre and eccentricity, and transport facility speed that tows the proposed device. Said disk are furnished with appliances to turn the disks relative to each other with subsequent fixation of axles.

EFFECT: higher quality of track removal.
