Magnitude 80
Six-axle heavy-haul references spanning beam, recessed and flat decks with a nominal 28 ft main deck. Axle-module arrangement and support conditions need the configuration drawing and load chart.

A model name or nominal class does not establish usable payload. The rating conditions and build-specific questions below remain part of the selection.

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: 80 tons in 16ft/ 70 tons in 12 ft as a 3+3
- 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.
