Support rollers MOBILE end girders of bridge with one beam suspension crane

摘要

The invention relates to handling mechanical engineering, namely to bridge with one beam suspension cranes are used for lifting and moving loads. The technical result while using the claimed utility model is to reduce the height and mass of the crane flight path of the beam and increasing the lifting height by reducing the height and width of the supporting rollers having frusto eccentric with eccentricity E in the direction of the reference circle R, with the radius R _M - smaller radius support circle r, truncated height H _p, and the width K - at least two reference radii r circumference for each size.
