Double Girder Bridge Crane

A double girder overhead travelling crane for heavy loads. The catalogue lists 55 configurations: eight ratings from 5 to 50 t across spans of 13.5 to 31.5 m, at a 9 m height of lift and duty group A5 / 2M. Hoisting speed falls as the rating rises, from 5 / 0.8 m/min at 5 t to 0-3.2 m/min at 50 t, which is why it is printed on every row instead of stated once. Maximum wheel load is not published here: within a single rating the catalogue contradicts itself, 231.2 at a 13.5 m span against 136.5 at 22.5 m, both at 40 t, and the question has gone to the manufacturer. One cell is missing: 5 t stops at 28.5 m.
