As the crane trolley accelerates and brakes across the bridge, it transmits lateral forces perpendicular to the runway rails. For cranes utilizing guide rollers, the 4th Edition outlines how these forces concentrate differently, often requiring direct consultation with the manufacturer or adhering to standards like . 3. Longitudinal Surge Forces

: Single-beam systems used for linear material transport paths.
