FIELD: bridge-building industry. SUBSTANCE: machine is based on wheeled chassis and can be used for laying heavy mechanized bridges with adjustable inter-track spacing. Machine can carry, lay and remove bridge from obstacle with mechanized locking its position in transportation. Locking and contraction of tracks are performed by means of single power-drive unit. Machine is provided with lateral supporting beams under span structure track of bridge module. Its moving components are made in the form of carriages. One hydraulic power cylinder is used for locking, extending and retraction of tracks for better operating characteristics and simplification of design. EFFECT: high efficiency. 1 cl, 9 dwgf
