What is a Shipping Container? Beginner’s Guide & an Easy Way to Open/Close

What is a Shipping Container?

Shipping Containers are also known as conex boxes, and are the cargo containers that allow goods to be stored for transport in trucks, trains and boats, making intermodal transport possible.  They are typically used to transport heavy materials or palletized goods.

Shipping Containers are used to protect transported cargo from shock and bad weather conditions, as well as keep storage products intact. They were first used in the 1950s and were initially developed for the purpose of commercial shipping.

Depending on the type of product that is going to be sent, the Shipping Container can vary in dimension, structure, material, etc. Characteristics of these shipping containers were later standardized, something that expedited transport without the need to load and unload the merchandise along the way.

There are different types of Shipping Containers for different types of transportation:

Common Types of Shipping Containers

Shipping Containers are another name for the conex boxes most used on the market.  Shipping Containers are typically suitable for any type of dry cargo: pallets, boxes, bags, machines, furniture, etc.

Common types include:

  • Dry Storage Container
  • Refrigerated Container
  • Open top container
  • Flat rack container
  • Open Side Container
  • Tanks Container
  • Ventilated containers

Dry Storage Shipping Container

Dry Storage Shipping Containers are your typical standard shipping containers.  Basic construction is made of steel, and hermetically sealed, without cooling or ventilation.  Sizes typically come in 20 ‘, 40’ or 40 ‘High Cube.  The High Cube category facilitates an increase of 13% of the internal cubic capacity and can handle the heaviest loads (coal, tobacco, etc.)

Refrigerated Shipping Container

Reefer Shipping Containers provide a temperature controlled environment. They have a power supply that connects to energy sources during transport. This allows the products to be transported at a constant temperature throughout the journey. They have the possibility to lower temperature from -18 ° to 30 °.  There are 20 and 40 foot models, in addition to the High Cube.

This type of Shipping Container is especially recommended for transporting food or products that need a low storage temperature.

Open Top Shipping Container

Open Top Shipping Container have the same measurements as the standard containers, but are open at the top because they have a removable canvas roof.  These containers facilitate the transport of bulky loads.

Flat Rack Shipping Container

Flat Rack Shipping Containers are like the Open Top, but also lack side walls and even, in some cases, front and rear walls. They are used for atypical loads and pay supplements in the same way as Open Top.

Open Side Shipping Container

Open Side Shipping Containers have the same measurements as standard containers; 20 or 40 feet, with the difference that they have a side opening. This allows for transporting very long merchandise, whose dimensions prevent it from being loaded by the back door.

Tank Shipping Container

Tank Shipping Containers are used for the liquid transport and made to carry dangerous as toxic, corrosive, highly combustible chemicals, as well as oil, milk, beers, wine, mineral water, etc. They have the same dimensions as a Dry Shipping Containers, but their structure is different, as they include a polyethylene tank inside.

Ventilated Shipping Containers

Ventilated Shipping Containers are made for transporting products such as coffee or cocoa beans, which must be ventilated in transit; sometimes these units are called “coffee containers”.

Shipping Container Opening and Closing Tool

A Shipping Container (also known as Intermodal ContainerISO Container,Railroad Container, and certain Truck Trailers)  is a large standardized shipping container, designed and built for intermodal freight transport.   Shipping Containers can be used across different modes of transport.  They can go from ship to rail to truck, without unloading and reloading their cargo.

The metal doors on the shipping containers on these containers are standardized.  Shipping Containers use the same type and style of doors and locking bars, which our tool can be used.

Lengths are as follows: 20′, 40′, 45′, 48′, 50′, 53′. All these containers are globally used to transport cargo. The 53′ length is now, the new the standard length.

Here are some likely reasons a Shipping Container door will not open or close.  Our tool helps to address these issues.

  • Doors and lockrods may warp or container frame is racked so that the door gear will not operate correctly. This may be caused by cargo shifting during transit. Look at the container to make sure that the doors are aligned and level, both top and bottom.
  • The hinge pins and blade are seized due to corrosion.
  • The door gasket has been damaged and is preventing opening. Door gaskets are designed to present two or more fins against the structure or adjacent door. These are generally flexible but when the gasket is damaged, they may become hard or blocked thus jamming the door closed, or preventing it being closed.
  • Water has become trapped between frozen shipping container doors, particularly relevant to refrigerated cargoes, or containers with moisture releasing cargoes in cold weather.
