The most common types of container currently used are the following:

20 ft (6 m.) For solid charge
For general uses and solid charge. 20 ft (6 m.) Long. Are 8 ft (2.4 m.) Wide, so that the load center is 48 inches (1.200 mm.)

Container of 40 feet (12 m.) For solid charge.
For general uses and solid charge. Container of 40 feet (12 m.) Long. They have 8 feet (2.4 m.) Wide, so that the load center is 48 inches (1,200 mm.)

Open top
Containers of 20 feet (6 m.) And 40 feet (12 m.) With open top, for transporting goods are not damaged if they are exposed.

Tank container
Tank-container 20 feet (6 m.) For the transport of fluids (such as chemicals) within a frame type box. They may be 8 feet (2.4 m.) Or 8.6 feet (2.6 m.) Tall.

Half-height container
Container-silo of medium height. It can be open, hardtop or canvas, and solid walls or cage. Is 4 feet (1.2 m.) Or 4.3 feet (1.3 m.) High and can carry minerals or semi-finished materials.

Flat Rack
Flat folding containers: They consist of a flat platform and ends provided with vertical hinges that may be to form a module or container can be folded to allow the storage container in question.

Reefer container
Refrigerated containers 20 feet (6 m.) And 40 feet (12 m.) With doors at one end and a refrigeration unit incorporated in the end.

The container standards are established by the International Standards Organization, ISO (International Standards Organization) and some of the measures and weights are:
Maximum weight:

20 feet (6 m) 44,800 lb (20.320kgs)
40 feet (12 m) 67,200 lb (30.480kgs)

However, a container may inadvertently loaded up to 10% more than specified, or off-center load. Therefore, a vehicle transporting containers must have an operating capacity of 75,000 lb (34,000 kg), with load center of 1,200 mm.

measures Both measures 20-foot (6 m) as 40 feet (12 m) for solid filler can have the following measures in millimeters:

Designation Overall height Internal height Overall width Overall length Internal width (40 feet) inside length (40 feet) Total length (20 feet) inside length (20 feet)

All containers are equipped with wrought iron corners each of the eight corners (4 superiores and 4 below).

Each of these parts has a groove-shaped openings in both ends and the upper or lower face. A twistlock (twist lock), is inserted into the opening by the spreader belonging to a mobile equipment, which rotates 90 °, whereby the twistlock (Twist lock) is fixed to the container and locked, and it is ready for transport. The notches on the sides are for fastening in stowage for shipping.

Many containers box structure both feet 20 and 40, are provided with channels through which the forks, so that they can be manipulated by them are introduced.


They have developed special versions of containers to meet specific needs of specific trades. For example:

Matson Lines, a shipping line linking the western part of the United States to Hawaii, use a special container of 44 feet (13.4 m).-
Sealand, 35 and 40 feet. The type of 40 feet in length can be handled either through the corners located at 35 feet or 40 feet located. The former are of Sealand type differently from the ISO. The special containers are less than a third of the total population of containers, but indicate the need to adapt to unusual situations whenever necessary. They conform to ISO standards for weight, and are lifted from the same points as standard containers.


Like most innovative and progressive ideas that have caused greater impact on the world, the concept of containerization has its positives and negatives.

The advantages are:
  • You may transport door to door.
  • It reduces paperwork and warehousing costs and inventory.
  • They are not precise intermediate manipulations, resulting in:
  • Less damage.
  • Reduced risk of theft.
  • Less packaging costs.
  • Increased labor productivity.
  • Labor is required less, significantly reducing costs.
  • The uniformity of the tasks minimizes the need for technical training.
  • The constant load symmetry makes capital investments to long-term use.
  • A wide range of goods can be transported by container.

Possible disadvantages are:

A large initial investment capital is needed to start the transport containers (containers, ships, terminal facilities and equipment.)

Some goods are not suitable or not economical to transport container.

Large-scale utilization is required. The containers are not always full when they are sent to the destination, and a container that is not fully loaded reduces profitability.

It is not always adequate cargo handling at the receiving location.

The fluctuating intensity in transport between two specific points adversely affects productivity.
