Types of container chassis
There are many different types of container chassis, each suitable for particular uses and specifications. The most prevalent kinds of container chassis are as follows:
Gooseneck chassis
Gooseneck or fixed gooseneck (FGN) chassis have a set gooseneck structure that is affixed to the front of the chassis frame. Through the use of twist locks, the chassis can be fastened to the container using this design by moving the front of the container onto the gooseneck. Heavy loads, such as apparatus and equipment, are frequently transported using gooseneck chassis because they provide greater stability and weight distribution.
Straight frame chassis
Fixed or straight-frame chassis have a linear frame structure that spans the entire length of the chassis. Twist locks mounted directly on the chassis frame secure the container to the chassis. The most common container chassis is straight-frame chassis as they’re versatile, simple to use, and can support an array of container sizes and types.
Drop frame chassis
Extendable drop frames (EDF) or drop frame chassis have a lower frame structure at the back of the chassis that slides to create a bigger cargo area. This construction is especially helpful for moving high-cube containers that are higher than usual. Drop frame chassis are also used to transport bulky or overweight goods like turbines and generators.
Extendable chassis
In order to accommodate various container sizes, extendable chassis, also referred to as telescopic chassis, have a frame structure that can be extended or retracted. This design is especially helpful when transporting containers of various lengths or when hauling several containers of various sizes. In intermodal operations, where flexibility and adaptability are essential, extendable chassis are frequently used.
Parts of a container chassis
A container chassis comprises an assortment of elements that work together to move containers safely from one place to another. The fundamental parts of a container frame are as follows:
Kingpin
The Kingpin is a metal pin that connects the container to the chassis and is positioned at the front of the chassis frame. The container’s twist locks are secured to the chassis during transit by the Kingpin, which slides into a corresponding slot.
Twist locks
Twist locks are mechanical devices that attach the container’s corner castings onto the corner fittings of the chassis. This secures the container to the chassis. There are many different types and designs of twist locks, including manually operated, partially automated, and completely automated models.
Landing gear
When the trailer is detached from the truck tractor, the weight of the trailer is supported by a pair of retractable legs at the back of the chassis called the landing gear. The landing gear, which can be either manually or electrically controlled, is crucial for a secure container loading and unloading process.
Axles
The structural elements known as axles attach the wheels to the chassis structure. Depending on the weight and size of the container being transported, container chassis usually have two or three axles. Axles may have mechanical or air suspension systems installed to dampen vibrations and impacts during transportation.
Suspension
Connecting the chassis frame to the axles with suspension systems gives the container a smooth ride and lessens the effect of bumps and other road obstacles. Suspension systems can be mechanical or air-based and come in a variety of designs, like leaf springs or airbags.
Tires
To ensure secure and effective transportation, tires are the only point of contact between the chassis and the road surface. Depending on the number of axles and the load-carrying capacity of the chassis, container chassis usually have eight to twelve tires. To ensure proper traction, braking, and stability, tires must be regularly maintained and replaced.
Common uses of container chassis
The use of container chassis is extensive, with everything from domestic transportation and storage to foreign trade and logistics. The following are some of the most prominent uses of container chassis:
Intermodal transportation
