The purpose of this list is to provide a sample of the various types of equipment that are contained in Alaska Marine Lines fleet. There are variations in size and weight. Please confirm specific equipment specifications if cargo being shipped is close to equipment specification limits.

Cargo best suited for platforms is cargo that cannot be loaded or unloaded from  a container and does not require protection from weather. For cargo that is moving on standard platforms, the maximum cargo height is determined by the legal limits of highway operations. In most western states the cargo and platform height cannot exceed 9'6" and 14' while loaded to the chassis. Also, cargo width is limited by highway laws. Cargo up to 8'6" in width is okay. Please call if you have cargo that you think might exceed these dimensions. We can make special arrangements for these loads.  

Tare: Weight of the container without cargo.

Payload: Maximum cargo weight the container is designed to carry.

Gross: Maximum designed weight of container with cargo.

Highway Max: Estimated maximum cargo or payload weight allowed by Washington State while moving on standard tandem axle chassis on public roads. Uneven weight distribution of load can reduce these weights significantly.
