Lashings
Container lashing is a process that involves securing and stabilizing cargo inside a shipping container, whether it is a sea, land or air container.
For this purpose, an exhaustive study is carried out through force calculations in order to stipulate the quantity and type of fastening to avoid displacements during transport.

Containers
standard (Dry Van)
The most common. They have a standard size (generally 20 or 40 feet) and are used to transport general cargo.
20 feet (20′ DV)
Approximate dimensions of 5.9 meters long, 2.30 meters wide and 2.28 meters high. It has a payload capacity of about 25-28 tons.
40 feet (40′ DV)
Dimensions approximately 11.90 meters long, 2.30 meters wide and 2.28 meters high. It has a payload capacity of about 26-27 tons.
High Cube
Similar to standard, but taller (approximately 1 additional foot in height), for carrying bulky cargo.
20 feet (20′ HC)
Although not as common, some 20′ HCs are used for specific loads. Its dimensions are similar to the standard 20-foot container, but with more height.
40 feet (40′ HC)
This is the most common type of High Cube container. It is 11.90 meters long, 2.30 meters wide and 2.55 meters high.
Open Top
It has no fixed ceiling. Instead, it uses a flexible cover (usually a tarpaulin), which allows loading and unloading of goods from above using cranes or other lifting equipment.
20 feet (20′ Open Top)
Dimensions approximately 5.90 meters long, 2.30 meters wide and 2.27 meters high.
40 feet (40′ Open Top)
Dimensions approximately 11.90 meters long, 2.30 meters wide and 2.27 meters high.
Flat Rack
They have no side walls or roof, allowing the transport of irregularly shaped or oversized cargo, such as heavy machinery.
20 feet (20′ FR)
With dimensions of 5.90 meters long, 2.36 meters wide and 2.33 meters high with a capacity for heavy loads.
40 feet (40′ FR)
With dimensions of 11.90 meters long, 2.36 meters wide and 1.94 meters high, designed for longer and heavier loads.
