What changes with the configuration
Each deck form keeps its own height, clearance, well and option evidence. A beam-deck usable span is not automatically equivalent to the nominal deck length on a flat-level reference.

Fontaine
Magnitude 55H
A hydraulic-detachable lowbed family with flat, recessed and beam-deck references. Deck form, width and axle-spacing options are kept separate so a dimension from one build is not applied to another.

How to read this model
A detachable lowbed family with materially different recessed, flat and beam-deck forms. The family name groups research; it does not establish one universal support surface.
What controls the shortlist
Match the load-bearing interface to the deck form before comparing the lowest height. Machinery with full-width tracks and a load designed to bear on beams can demand different structural arrangements.
Questions for the build-sheet review
- Which DSR, FLD or beam-deck form is specified?
- What transverse support and contact layout is approved?
- What source establishes the height and clearance in the selected state?

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: 55 tons in 12-foot length with 4 axle close coupled or single axle stinger - GAWR and GVWR 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.
