METHOD TO REDUCE SLIPPERINESS OF SNOW AND ICE SURFACE OF PAVEMENTS AND PEDESTRIAN WAYS AND DEVICE FOR REALISATION OF THIS METHOD Russian patent published in 2014 - IPC E01H5/00 E01H5/12 

FIELD: construction.

SUBSTANCE: device for reduction of slipperiness includes: a chain cutter 8 arranged across the working motion and comprising a frame 7, with two supports 9 installed in it, where shafts 10 with sprockets 1 are located, along which a chain 13 moves with mounted cutters 14 and brushes 15; a rotor distributor of loose solid particles 1 with castor wheels 3 and a support 4, which is fixed to a base tool carrier 17. The cutter is capable of changing the depth of treatment of the snow and ice surface due to a hinged suspension 5 to a rotor distributor of loose solid particles and a hydraulic cylinder 6. Motion of the chain is provided by a hydraulic drive 16. Supply of the working fluid into the hydraulic drive and the hydraulic cylinder, and control of this supply is carried out from a hydraulic system of the base carrier.

EFFECT: invention makes it possible to reduce slipperiness of surface of pedestrian ways and pavements.
