Current manufacturer reference
A current three-axle TKHDG lowbed with a 25 ft 9 in main deck and a 120,000 lb concentrated rating over 12 ft.
The usable well, loaded height and neck clearance govern the starting configuration.
Front access depends on detaching and reconnecting the hydraulic neck. Review the approach, supporting ground and the machine’s lowest components with the actual operating procedure.
Track or tyre contacts must sit on suitable structure inside the well. A nominal well length does not establish unobstructed support space.
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.
Manufacturer-stated main deck length
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.
Track footprint length alone is insufficient. Record where the rollers react into the tracks, and check side rails, outriggers and the position of the machine centre of gravity.
Wide tracks need a documented support path. Outrigger boards are not a general-purpose extension of the trailer’s structural rating.
Concentrated wheel loads need deck and crossmember verification. Record the actual tyre contact lines rather than treating the whole machine length as load distribution.
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.
