Fixed, adjustable and self-handling chassis that carry ISO, domestic, reefer, tank and specialty container entities.
A container chassis is defined by its container interface and supporting frame, not by the contents of a box placed on it. Keep the container, tank or refrigeration equipment as a separate carried entity. Container length alone does not establish that a chassis has the correct locking positions or load distribution.
| Decision | What changes | Ask for |
|---|---|---|
| Fixed or adjustable chassis | A fixed frame supports a defined arrangement; sliders or telescopic sections alter position or length. | Container standard, twist-lock pattern, lock positions and operating state |
| Tank or refrigerated container | Carried equipment may need a particular support arrangement, protection or genset. It remains distinct from a tank trailer or reefer body. | Container compatibility, interfaces and power/support requirements |
| Self-handling or conventional lift | A sidelifter or tipping arrangement changes how the container reaches or leaves the chassis. | Lift/tip envelope, stabilizers, working ground and load chart |
Document container gross weight and the actual support arrangement; do not assume a permitted container weight is the chassis payload. Plan terminal access, axle distribution and chassis operating position for the route and handling equipment.
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.

2 specification references cover 1 trailer architecture. Open the specification library for model-specific documentation.
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.
Frame geometry, lock positions, adjustment and self-handling equipment define the chassis; the carried container remains a separate entity.
One documented container length and lock pattern.
Dropped centre rail accepts a compatible tunnel container.
Sliding frame changes supported container positions.
Chassis carries a separately framed ISO tank entity.
Onboard lifting arms transfer the container beside the chassis.
A chassis or self-handling carrier built around a documented container interface, length and locking pattern is canonical here; the carried container remains a separate entity.
