Dimensions of 20ft Shipping Container

Shipping Container Dimensions

The three most popular container dimensions you will come across are the 10-foot shipping container, 20-foot shipping container, and the 40-foot shipping container.  Here we explain the dimensions of the 20-foot shipping container.

20ft Shipping Container Dimensions

The standard 20ft shipping container is a popular pick for companies who need easy maneuverability.

20ft containers have a distinct advantage over the 40ft containers and that is that they are significantly easier to transport.  They are also cheaper than the 40ft containers to the tune of several thousand dollars per container and are also cheaper to transport.

Wear and Tear

Shipping containers often take a beating, traveling around the world, being exposed to freezing conditions, and rust due to seawater or when the frost has melted.

During the cold season, and in freezing parts of the world, our shipping container tool can benefit the opening of frozen shipping container doors in freezing conditions and hard to open or rusted containers once the winter has ended.

Injuries often occur as a result of personnel trying to open and close difficult container doors, often the result of inappropriate techniques being used to open them.

Shipping container doors are not typical doors and there are 4-5 hinges per door.  The hinge pins must be lined up correctly for the doors to be free to fully open and close.

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

• The 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 container door 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 from being closed.
• Water has become trapped between the doors and frozen, particularly relevant to refrigerated cargoes, or containers with moisture-releasing cargoes in cold weather.

Designed to fit and extend the door latch handles on side-by-side doors found on the following units with the safety of the truck driver, operator, and worker foremost in mind:

• Dismountable Shipping Cargo Containers
• Refrigerated Shipping Cargo Containers
• Semitrailer Dry Freight Cargo Vans
• Semitrailer Refrigerated Freight Cargo Vans

This intermodal container (also known as ISO Container or Conex Box) cargo inspection tool and leverage safety bar is to aid in opening and closing side-by-side doors found within Dismountable Shipping Cargo Container Transportation Industries (Railroad, Harbor, and Trucking Industries).

Eliminates the Need for a crescent wrench, screwdriver, hammer, and crowbar which are commonly needed/used to open stuck frozen shipping container doors.

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 Containers 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 Door Diagram and Troubleshooting

Shipping Container Diagram

1. Doors

Two door leaves are fabricated from two vertical rolled hollow sections and 2 horizontal c section members. The frame is infilled with corrugated steel paneling.

These are normally attached to the rear corner posts each with four drop forged steel hinge blades. The blades allow 270 degree opening which allow the doors to swing back against the container side wall.

(Cargo may shift during transit. Look at the container to make sure that the doors are aligned and level, both top and bottom.  In cases where the container frame is racked and the door gear will not operate correctly.)

2. Lockbox

The lock box is a steel box welded to the right hand door which overlaps a staple welded to the left hand door. A padlock, normally type CISA type 285 66 can then be attached inside the lock box through the staple and is then protected from direct attack, hindering attempts to gain entry to the container.

3. Lockrods, cam keepers, handles

Each door is fitted with 2-4 vertical lock rods to enable opening, closing and locking of the doors.

At the end of each lock rod (top and bottom) is a cam welded in place which engages with knuckles, also known as cam keepers.

Shipping Container Cam Keepers

The action of engaging the cams to the keepers forms an anti-racking function.

(In certain cases, often unfortunately too many, contents of the shipping container may have shifted, or containers even dropped, causing shipping container doors and lockrods to warp)

The door handle rotates the lockbar to initiates the door opening process by forcing the cams out of their keepers.  Each door handle has a door locking handle retainer that slides over the door handle when in locked position.

4. Rubber gaskets

Rubber gaskets are fitted to the container doors during the manufacturing process and prevent water ingress.

(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.)

5. ISO markings and CSC plate

ISO markings and a consolidated data plate allow worldwide intermodal transport when left in place and updated as necessary.

6. Hinge pins

Of course for a door to work, you need hinges.
