The current BWS air-detachable-gooseneck double-drop family, kept distinct from mechanical and hydraulic neck systems.
Two deck transitions frame the central well; front detachment is not a loading method for this reference.
Loading path
Air-assisted front detach
Plan crane placement, winching or approved rear loading around the fixed neck and rear bridge. Obtain the procedure for the exact deck style.
Supporting the load
The footprint must fit between transitions. Raised-centre, beam and flat-deck variants may support the same load differently.
Dimensions that govern this configuration
Usable support space, nominal deck spans and the overall transport envelope remain separate measurements.

Ratings & support conditions
The exact build’s load chart is required. A model-family capacity range does not establish this configuration’s rating.
Tare, gross vehicle rating and structural load ratings describe different limits. None alone establishes allowable payload or legal axle loads.
Plan around the actual load
These applications identify what to investigate. Suitability depends on the transported assembly, support points and the selected trailer build.
Excavators
Will the stowed machine fit the well?
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.
Obtain the exact BWS build sheet and configuration-specific load chart before matching a load.
Do not infer payload, legal axle loading, production years or extension-state capacity from the family name.
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.
