What changes with the configuration
Closed and extended usable-well references are separate. The selected state must retain its own load chart and support requirements, including where the load bridges the extended section.

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.

A model name or nominal class does not establish usable payload. The rating conditions and build-specific questions below remain part of the selection.
How to read this model
An extendable detachable lowbed for investigating loads that require a longer well. The extension mechanism adds a structural state; it does not simply create more ordinary deck flooring.
What controls the shortlist
Compare support spacing, stiffness and load position before using the larger open dimension. Retain the actual extension state in the configuration brief and ask for the corresponding rating evidence.
Questions for the build-sheet review
- Which locked extension position is planned?
- What load span and support pattern does the open chart require?
- What changes to turning, ground clearance and securement access follow?

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: 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.
