FIELD: construction.
SUBSTANCE: invention relates to the method of installation of support parts on railway spans, consisting in installation of mobile and fixed support parts on the mobile and fixed axes of span resting. Some mobile support parts are made as movable in all directions, and one of them is linearly movable in longitudinal direction. Support parts that are movable in all directions are installed in pairs on the mobile and fixed axes of the span relative to main beams or trusses of the span symmetrically and equidistantly from the longitudinal axis of the span, and a fixed support part is installed along the longitudinal axis of the span on the fixed axis of resting. The support part linearly moving in longitudinal direction is installed linearly on the mobile axis of resting. Support parts moving in all directions may perceive only vertical loads from the span. Linearly moving support parts may perceive only horizontal transverse loads without possibility to perceive vertical reactions. The fixed support part may perceive only horizontal longitudinal and transverse loads without possibility to perceive vertical reactions.
EFFECT: increased reliability.
