What changes with the configuration
Closed/open overall lengths remain attached to their axle/configuration codes. A rating from one code or state cannot establish capacity for another reference merely because the family name is shared.
An extendable straight-deck family with 53 ft closed and 90 ft extended overall references. The catalogue separates axle and configuration codes, with capacity evidence retained only for the documented state.

A model name or nominal class does not establish usable payload. The rating conditions and build-specific questions below remain part of the selection.
An extendable straight platform for investigating long freight. Its useful feature is the documented range of structural states, not a single maximum length treated as a universal deck.
Closed/open overall lengths remain attached to their axle/configuration codes. A rating from one code or state cannot establish capacity for another reference merely because the family name is shared.
Use the exact support drawing and extension-state chart. Check whether the load is expected to bridge the gap, how dunnage bears on the structure and where restraint access remains available.
Selection commentary is based on the documented references below. Check the selected source and its review date; commentary does not supply missing manufacturer values.

Spans compare documented values. They are not positioned or scaled to the photograph.

View dimension source ↗Request these values for the actual configuration. An absent value is not zero and does not establish a fit.
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.
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.
Documentary statements retain their original conditions. Only unambiguous numeric fields enter dimensional checks.
