Longitudinal part includes sleeper connected with bank and bottom supports. Sleeper is made of assembly sections in form of floating pontoons of triangular form with side crossmembers hinge-secured on side walls of adjacent pontoons. Pontoons are hinge-connected to each other both inside section and to pontoons of adjacent sections. Free hinge joints of extreme section are connected, in their turn, by wire ropes with bank supports. Each assembly section is provided with separate bottom support. Bottom supports are fastened by wire ropes to middle part of assembly sections and are arranged at a distance from each other equal to length of one section. ^ EFFECT: enlarged operating capabilities, reduced labor input at mounting of boom. ^ 2 cl, 9 dwg
