FIELD: construction.
SUBSTANCE: invention relates to ice-breaking equipment. Device is made in the form of cable-stayed bridges, at the same time: the length of the cables can vary depending on water level fluctuations in the water reservoir; thus providing constant force of their tension. On the cables there installed are dampers for suppression of tension force oscillations. Distances between points of fastening of cables to ice should not exceed half of wave length of static deflection of ice cover from action of static load. Ends of ferry are equipped with ramps sliding on ice and hinged on shore.
EFFECT: invention can be used in creation of ice crossing.
