FIELD: structural or constructional details of bridges, particularly movable reinforced concrete or iron beam bridge piers.
SUBSTANCE: roller is molded as two parabolic semi-cylinders having common axis of symmetry and facing each other. The semi-cylinders are truncated with focal planes transversal to plane of semi-cylinder symmetry and pass into straight round semi-cylinders along section line. Semi-cylinders of pads and rollers have equal radii or curvature.
EFFECT: improved bridge beam vibration damping, increased pier area and bearing surface.
