Lowbed and modular systems designed around low loading height, detachable or fixed necks and specialized heavy-load support.
Lowbed and specialized heavy-haul selection begins with the load-support drawing, loading procedure and route. A detachable neck creates a front-loading path; a low deck describes where the load travels. Deck form, neck mechanism and auxiliary axle components must remain separate parts of the specification.
| Decision | What changes | Ask for |
|---|---|---|
| Fixed or detachable neck | Front access can help self-propelled machinery reach a low well. Fixed-neck equipment may use rear loading or lift-on placement instead. | Operating manual, ground support, tractor provision and approach clearance |
| Full deck, beam or perimeter | The load may bear on continuous flooring, beams or separated frame members. A similar nominal ton class does not make these load paths equivalent. | Approved contact points, concentrated chart and transverse support |
| Jeep, booster or modular running gear | Auxiliary equipment changes connections, axle spacing and manoeuvring. The exact assembly controls the load distribution. | Connection ratings, setup drawing, steerability and configuration-specific tare |
Do not equate structural capacity with legal payload. Tractor ratings, reactions, axle spacing, seasonal restrictions and route permissions are separate checks. A lower deck still needs sufficient ground clearance through the loading site and route.
For route-specific checks, start with the applicable provincial authority. Alberta permit resources ↗ and Ontario permit resources ↗ explain their respective processes; neither is a Canada-wide clearance rule.

144 specification references cover 7 trailer architectures. 113 documented configurations can be explored in the catalogue.
Model references are supported by manufacturer documentation. Check each configuration for its available dimensions and ratings.
Each reference shows the feature that controls classification. It is not a dimension, rating, compatibility or availability source.
The low carrying deck is permanent and the front neck does not detach for loading.
The front neck detaches from the low well to create the defining front-loading path.
