The invention discloses a tolerance type portal frame trolley bearing rail beam for a double-trolley quay crane. The tolerance type portal frame trolley bearing rail beam comprises a bearing rail beam panel, a bearing rail beam web, longitudinal stiffening ribs and transverse stiffening ribs. The rail bearing beam panel is arranged on the panel of the box body structure; the rail bearing beam web plate is arranged on the web plate of the box body structure; the longitudinal stiffening ribs are continuous and are inserted into each main partition plate of the box body structure; the number of the transverse stiffening ribs is multiple, and the transverse stiffening ribs are arranged between the main partition plates respectively. Rail arranging requirements can be met without correcting the box body structure, so that the mounting precision of the rail is high.
