FIELD: construction, road engineering.
SUBSTANCE: invention is related to the field of bridge engineering, in particular, to technological devices used for installation of bridge spans. Device for installation of bridge spans comprises two rotary installation trusses installed on sides of adjacent bridge supports. Trusses are hung on supports by means of fast-dismountable vertical swivel joints. On completion of another span installation back hinges of such trusses are split, and trusses turn around front hinges by 180° to match turned ends of trusses with hinge units of another bridge support.
EFFECT: reduced labour intensiveness and duration of bridge-construction works.
