One of the basic infrastructures for the handling of merchandise and ships in all types of ports are the mechanical automated Stacking Cranes, especially in the commercial ports where the loading, unloading, storage, and unloading are key actions for the development and operation of these ports.
The stacking cranes are used to load between the port and the ship, in order to organize and stack it. After the large port cranes, the structures that usually occupy the line of sight of ports around the world, we find the smallest formats, capable of working in even smaller spaces. The first of these cranes is the reach stacker crane, also known as a forklift.

Container stacking crane
A container is a cargo container intended for international and national transportation through sea, inland waterway and/or air routes.
The size and shape of it vary depending on the length and height. The form and characteristics of the same are regulated in accordance with the ISO-668: 2 (International Organization for Standardization), for that reason in some places containers are also known as ISO containers.
This regulation also facilitates the handling of the same to the decks of the ships and the cargo spaces of ships and trucks.
As for the characteristics of the containers, it should be noted that they are usually made mainly of steel, but there are also some made of aluminum and some others made of wood reinforced with fiberglass. In most cases, the floor is made of wood, although there are recent examples where the floor is made of bamboo.
Inside they have a special anti-humidity coating, designed to avoid humidity and incumbencies of time along the way.
Another distinctive feature of any container is that they have hooks on each corner that allow them to be hooked by cranes, as well as their lashing on boats and trucks.
As for the identification, all the containers carry an alphanumeric identification to follow up and avoid its loss. These codes are usually four letters and seven numbers. As an example: MDGU 154570. The maximum load of a container generally varies according to the shipping company responsible for carrying out the transport and the type of container. Containers with an international standard of 20 feet have a maximum gross weight of about 29 tons – including the load plus the weight of the container itself – and the largest of 40 feet have a maximum gross weight of 32 tons.
What is an Automated Stacking Cranes?
The automated handling of containers is the next step in the evolution of container crane technology that began with the introduction of containerized shipping in the 1960s. Automated stacking cranes (ASC) are rail-mounted cranes used for yard-stacking and in-stack transportation of containers. ASCs deposit and pick up containers from dedicated interchange areas located at both ends of the stack.
Straddle carriers are trusted by terminal operators around the world for their ability to enable faster ship-to-shore crane operations and more efficient landside operations. Straddle carriers are highly versatile machines that can be used for a wide variety of applications and terminal operating modes.
The straddle carrier can undertake self-repositioning, handling, stacking, loading, and unloading, as well as transporting empty containers. The benefits of automating these tasks include energy savings, lower maintenance costs, environmental protection, and regulatory compliance. The straddle carrier has high mobility and flexibility, enabling modular retrofit for current operations in existing terminals.
A rubber-tired gantry crane is a mobile gantry crane used in intermodal operations to ground or stack containers. Inbound containers are stored for future pickup by drayage trucks, and outbound are stored for future loading onto vessels.
