FIELD: construction.
SUBSTANCE: invention relates to the field of crossing-and-bridge equipment, namely, to bridges of driveways of mechanized bridges. Each spreader is made in the form of frame-comb (1), consisting of longitudinal beam (4), combined with transverse beams (5, 6, 7), which with their ends are inserted into working holes (8), available in vertical walls lengthwise stiffness ribs (9, 10) of axles of bridge roadway (2). Rock-lock retainer (18) is mounted on bracket (17) to fix folding spreader of roadway in transport position on beam element (6).
EFFECT: span machines of mechanized bridges are intended to increase bridge throughput capacity.
