What changes with the configuration
A shared nominal main-deck span does not make the deck forms interchangeable. Keep deck-height evidence, ground clearance and load support tied to the chosen MDSR, MFLD or beam-deck reference.
RGN / Detachable Gooseneck · SteelFontaine
Fontaine
Magnitude 60
A hydraulic-detachable family covering recessed, flat and beam-deck configurations. The references share a nominal 26 ft main-deck length, while deck form and height evidence remain configuration-specific.

How to read this model
A hydraulic-detachable family spanning recessed, flat and beam-deck references. It supports a comparison of load interface and loading method rather than a single capacity-number shortlist.
What controls the shortlist
Determine whether the load needs a floor, recessed track positions or separated beam support. Ask for the exact concentrated-load conditions rather than deriving payload from the family’s number.
Questions for the build-sheet review
- Which deck form and physical supports are installed?
- Where is the load centre of gravity relative to the neck and rear group?
- Which manufacturer chart applies to the selected running-gear arrangement?

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
- Deck-height scope or source consistency requires review; do not derive a loaded-height result from the artwork or model name.
- Rating basis: 60 tons in 12-foot length with 4th axle close coupled or 3+1 axle configuration - 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.
