FIELD: construction.
SUBSTANCE: invention can be used to create an ice crossing. Device for creation of ice crossing is made in the form of pylons installed on banks on both sides of planned crossing, to upper ends of which there are bearing ropes attached. Vertical suspensions are fixed on them by the upper end, and their lower ends are frozen into the ice cover at a distance from each other, which does not exceed half the wavelength of static deflection of the ice cover from the action of static transverse load. Pylons are installed vertically and are made with devices for changing their height. Braces are provided with devices for changing their length.
EFFECT: increasing carrying capacity of ice crossing depending on weight of transported cargo.
