38 in loaded deck / 19.5 in tyres
A steel centre frame with aluminium decking and one drop behind the upper deck. Three published deck-height references keep tyre, clearance and tare differences visible.
Treat the upper deck and lower main deck as separate working areas.
Side or crane loading needs access to both deck levels. Drive-on loading requires the specified ramps and a checked transition path.
An overall trailer length includes the upper deck and other structure. Do not subtract one published span to invent a usable lower-deck length.
Compare the changes in height, coupling or extension state before switching references.
Usable support space, nominal deck spans and the overall transport envelope remain separate measurements.
Documented spans Shared numeric scale
Spans compare documented values. They are not positioned or scaled to the photograph.

View dimension source ↗Tare, gross vehicle rating and structural load ratings describe different limits. None alone establishes allowable payload or legal axle loads.
These applications identify what to investigate. Suitability depends on the transported assembly, support points and the selected trailer build.
Use the manufacturer’s chart for the selected extension and support layout. An open telescoping centre is not a continuous solid floor.
Locate the skid rails over suitable structure. Check whether levelling blocks, isolators or delicate equipment prohibit support at other points.
Check the cradle and the trailer together. The cradle may concentrate weight or raise the load enough to defeat the height benefit.
Equipment selection requires verified weights and ratings, load support, coupling and axle analysis, securement planning and route review. This reference is not engineering, permit or route-clearance approval.
