A 20-foot (6.1 m) container is limited to 24 tonnes (26.5 short tons; 23.6 long tons) and two such can fit into a car for a 40-foot (12.2 m) container, or even three if double-stacking [citation needed], but not four unless very high axle load is permitted. The North American railways permit two 53-foot (16.15 m) containers as shown in the ...
Each unit of a double-stack car contains a single well; they often are constructed with three to five cars connected by articulated connectors. The intermediate connectors are supported by the centerplate of single trucks, often a 125-short-ton (112-long-ton; 113 t)-capacity truck but sometimes a 150-short-ton (134-long-ton; 136 t)-capacity one.
The length of a chassis corresponds to which container size will fit (i.e., a 40-foot-long chassis fits a 40-foot-long container), but some models are adjustable length. [3] A port crane lifts a container from a ship to a chassis for road transport. Twistlocks. Semi-tractor trucks hook up to chassis via the kingpin. When disconnected from a ...
The other cause for this decline is the dramatic shift of waterborne cargo transport to container shipping. Effectively a boxcar without the wheels and chassis, a container is designed to be amenable to intermodal freight transport, whether by container ships, trucks or flatcars, and can be delivered door-to-door.

Travelling by road. The sidelifter loads and unloads containers via a pair of hydraulic powered cranes mounted at each end of the vehicle chassis.The cranes are designed to lift containers from the ground, from other vehicles including rolling stock, from railway wagons and directly from stacks on docks or aboard container ships.
An intermodal container, often called a shipping container, or cargo container, (or simply "container") is a large metal crate designed and built for intermodal freight transport, meaning these containers can be used across different modes of transport – such as from ships to trains to trucks – without unloading and reloading their cargo.

The older wooden containers and the pre-ISO containers were rapidly replaced by 10-and-20-foot (3.0 and 6.1 m) ISO standard containers, and later by 40-foot (12 m) containers and larger. In the U.S., starting in the 1960s, the use of containers increased steadily.
Roll-on/Roll-off car carrying ship being boarded by articulated haulers at the Port of Baltimore RoRo ports and inland waterways of the United States. Roll-on/roll-off (RORO or ro-ro) ships are cargo ships designed to carry wheeled cargo, such as cars, motorcycles, trucks, semi-trailer trucks, buses, trailers, and railroad cars, that are driven on and off the ship on their own wheels or using ...
