FIELD: construction.
SUBSTANCE: method refers to the bridge construction area and can be used for installing bridge span structures. Mounted span structure is connected at one end to the swinging mast and is located on the overpassed structure, then a swaying mast is installed at the trestle support and pivotally connected to it, on the flyover structure of the trestle a motor vehicle with an attached guide device is attached to which the mounted span structure is attached and the thrust is carried out by moving the tractor forward while lowering the mast before installing the span structure on the support.
EFFECT: expanded functionality of the assembly method, which will reduce the complexity of operations when mounting a span structure in the construction of a metal overhead and thereby achieve a reduction in time and labor.
