Fontaine
Magnitude 75
A five-axle hydraulic-detachable family whose documented deck heights differ between recessed and flat or beam configurations. The selected deck form controls which measurements appear in the comparison.

Overall length is not usable deck length. A published side-rail width does not establish the unobstructed support width. Values above come from documentation, not from image measurements.
Capacity with its conditions
No comparable payload rating is established by this reference. Obtain the configuration-specific load chart.
Structural ratings do not approve axle loads, the tractor connection, route clearance or a permit.
What to verify
- Rating basis: 75 tons in 16ft as a 3+2 with gooseneck extension to 237" or 70 tons in 12-foot length as a 3+2 - GAWR and tire ratings determine legal payloads
- Match the selected deck, neck and axle configuration to the actual build sheet.
- Read the complete capacity and support conditions at the source; a model-family rating is not automatically transferable.
