A container chassis is a sophisticated piece of machinery with many components that all must function together. What are the crucial components of a chassis that are necessary for it to do its job of supporting intermodal containers?

Main Rails

The main rails sustain the weight of the container and form the framework of the container chassis. The rails are usually composed of high-strength steel and offer durability and structural integrity. Depending on the kind of container being transported, the main rails’ size and shape may change.

Suspension System

The suspension system is what keeps the container stable and the objects inside the container undamaged. The springs and equalizers that make up the suspension system take the brunt of bumps in the road. The container’s stability and balance are provided by the suspension system, which also serves to keep it from toppling over while being transported.


The connectors that secure the container to the chassis are known as pin/twist locks. These locks fit into the corner fittings of the container and are placed at each corner of the chassis. The locks’ purpose is to secure the container to the vehicle and keep it from moving while being transported.

A container chassis’ main rails, pin/twist locks, and suspension system are vital components that are necessary for its operation. These components give the container its structural integrity, a solid structure to rest on, and stability during transport.
