What changes with the configuration
Tyre-dependent loaded heights and a three-axle option remain separate references. An axle option with incomplete rating evidence must not inherit a rating silently from the two-axle reference.

How to read this model
A sliding-axle equipment platform whose running gear moves to establish the loading path. It is worth comparing with hydraulic-tail equipment when the machine’s approach and recovery needs control selection.
What controls the shortlist
Check the machine while the deck tilts and the axle group moves, not only in the final transport position. The selected tyre package changes the height comparison, while the winch and load chart answer separate questions.
Questions for the build-sheet review
- Which tyre and axle reference matches the serial-number build?
- What winch and ground-bearing setup is required?
- Are the exact loading-cycle and transport ratings documented?
Compare with a purpose
Selection commentary is based on the documented references below. Check the selected source and its review date; commentary does not supply missing manufacturer values.

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
- Documented optional configuration. Numeric ratings are withheld until the matching build-specific chart is confirmed.
- The 80,000 lb uniform rating is not the 50,000 lb concentrated rating.
- Confirm the transport lock position and axle count on the actual trailer.
- Loading method
- Sliding axle / tilting deck
- Axle arrangement
- 3-axle option; spacing per manufacturer reference
