The primary differences between domestic and marine chassis, based on the provided information, are their size (specifically height) and weight.
Domestic and marine chassis are specialized trailers used in intermodal transportation to carry shipping containers, but they differ in design and build to accommodate the specific types of containers they handle.
The main distinction, according to the provided reference, lies in their physical characteristics:
- Size (Height): A domestic intermodal chassis is bigger in terms of height. This design accommodates the taller 53-foot containers commonly used in North American domestic freight movement.
- Weight: There is a significant difference in weight. While a 53-foot domestic chassis weight can range from 500 to 700 lb, an ocean container chassis' weight is approximately 6500 lb. This substantial difference reflects the heavier, more robust construction needed for ocean-going containers and the often harsher marine environment.
Here's a quick summary of the key differences mentioned:
| Feature | Domestic Chassis | Marine (Ocean Container) Chassis |
|---|---|---|
| Size | Bigger in height (for 53-ft containers) | Standard heights for ISO containers |
| Weight | Lighter (approx. 500-700 lb for 53-ft) | Heavier (approx. 6500 lb) |
These differences highlight their specific purposes within the supply chain – domestic chassis are optimized for the lighter, taller containers used primarily within a single country's borders, while marine chassis are built to handle the heavier, standard-height containers that traverse oceans.
