Fontaine
Workhorse 51

A three-axle hydraulic-detachable lowbed with a 22 in deck-height reference and two documented usable-deck lengths. The shorter option is kept separate instead of inheriting the standard reference's rating.

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.

Structural ratings do not approve axle loads, the tractor connection, route clearance or a permit.

Configuration notes

What to verify

  • Rating basis: 51 tons in 12-foot length - 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.
