Fontaine
Magnitude 55MX
An extendable hydraulic-detachable lowbed with separate closed and extended well references. Opening the deck changes the documented support length; a closed-state rating must not be assumed to cover the extension.
Know the space. Know the limits.
Documented spans Shared numeric scale
Spans compare documented values. They are not positioned or scaled to the photograph.

Overall length is not usable deck length. A published side-rail width does not establish the unobstructed support width. Values above come from documentation, never from measuring the artwork.
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: 55 tons in 16-foot length (closed position) with 4 axle close coupled or single axle stinger
- 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.
