FIELD: bridge construction, particularly equipment for beam installation on main piers of beam bridges.
SUBSTANCE: device comprises piers and two parallel load-bearing strings stretched between the piers so that the strings are directed along axis of design position of each beam to be protruded into bridge span for accurate beam installation on support parts without beam displacement in transversal direction. Device also has support and suspended trolleys. Beam may be hanged to suspended trolley comprising electric drive for trolley movement along strings. Piers have string height control mechanisms, which change string heights over bridge piers. Suspended trolley may have mechanism, which puts front beam end on support parts.
EFFECT: decreased labor inputs for beam installation on main bridge piers.
