Stacking Cone to prevent container slipping

What is a Stacking Cone for a shipping container?

Stacking Cone is a key component for safely stacking and securing shipping containers during transportation or storage. This small but ingenious tool prevents movement or shifting of containers stacked on top of each other and ensures their stability even in challenging conditions, such as rough seas or unfavorable weather conditions.

The stacking cone is made of sturdy cast iron or steel, often coated with a protective surface such as hot-dip galvanization to resist corrosion and long-term wear. It is used for both shipping on ships and storage in ports, depots, or terminals. Stacking cones are most commonly made from high-strength steel castings and are designed for long-term use in the most challenging climatic conditions.

– The cone is used for short-term securing of the container against slipping

– Used for securing containers stacked on top of each other (stacking)

How does the Stacking Cone work?

The stacking cone works on the principle of connecting the corners of two containers – the bottom and top ones. The corners of the containers are equipped with standardized holes called corner castings, which allow the secure attachment of stacking cones. In practice, the stacking cone is placed between two containers, with its top and bottom parts fitting into the corresponding corners.

Thanks to its conical shape, the device provides stability, preventing horizontal shifting of the containers. Stacking cones often feature an interlock design, ensuring their firm attachment and preventing any movement of the containers during transportation. In some cases, stacking cones are designed with additional locks or mechanisms that further enhance security.

Types of Stacking Cones

There are several variants of stacking cones, which differ in design, purpose, and usage method. The following are the most common types:

1. Single Stacking Cone

This is a basic model with a simple design. The single stacking cone has two conical parts connected to the base. One conical part fits into the corner of the bottom container, while the other part serves to secure the top container. This type is ideal for use in ports or terminals, but also on board ships.

Advantages: Simplicity, low cost, easy to use.

Disadvantages: Not self-locking, which means that the stacking cone must be manually removed when handling the top container.

2. Self-Hanging Stacking Cone

This model is designed with a self-locking function, which means that the stacking cone stays in place even when the top container is lifted. It has a special mechanism that prevents the cone from falling out.

Advantages: Higher safety, suitable for use on ships.

Disadvantages: Higher price and more complex design.

3. Depot Stacker

The depot stacker is primarily intended for use in ports and warehouses. This type is not suitable for sea transport because it does not have sufficient resistance to vibration and sea movement.

Advantages: Efficient and fast stacking of containers on land.

Disadvantages: Not suitable for use on ships.

4. Intermediate Twist Lock

This type combines the functions of a stacking cone and a twist lock. It is mainly used to secure high stacks of containers and provides an additional level of safety.

Why use stacking cones?

1. Safety:

Stacking cones prevent shifting or sliding of containers, which is crucial when transporting on ships, where waves can cause dangerous movements. Without stacking cones, containers could fall into the sea, which represents not only economic losses but also environmental threats.

2. Efficient stacking:

When used properly, stacking cones allow for quick and precise stacking of containers, increasing efficiency in ports and terminals.

3. Resistance to adverse conditions:

Thanks to materials such as durable cast iron or steel, stacking cones can withstand extreme conditions, including high humidity, salt, and mechanical stress.

4. Compatibility:

Stacking cones are designed according to international standards, meaning they are compatible with containers worldwide.

What are the key features of Stacking Cones?

• Material: Cast iron or steel with protective coating (e.g., hot-dip galvanizing).
• Weight: Typically between 2–5 kg, depending on the type.
• Dimensions: Tailored to ISO corners of containers.
• Load capacity: Ability to withstand high pressure and load (e.g., stacking up to 6–8 containers on top of each other).
• Durability: Resistant to corrosion, extreme temperatures, and mechanical stress.

When and where to use the stacking cone “Stacking Cones”?

Sea transport:

Stacking cones are essential for safely stacking containers on ships, both below deck and on open decks. They ensure that containers remain in place even during heavy sea waves.

Ports and terminals:

In ports, stacking cones are used for organized container storage. These cones help optimize space and ensure stack stability.

Warehouses and depots:

For long-term container storage on land, especially in areas with a high risk of windy conditions.

What are the alternatives to Stacking Cones?

In addition to stacking cones, there are other devices used to secure containers:

• Rods:Twist Locks: Used to firmly connect containers to each other or to the deck.
• Bridge Fittings: Connect multiple stacks of containers and increase stability.
• Lashing Used to secure containers to the ship or stacks.

Frequently Asked Questions (FAQ)

What is the difference between a stacking cone and a twist lock?

A stacking cone ensures the stability of containers, while a twist lock is a mechanism that locks containers securely. Both devices are often used together.

How many containers can be safely stacked using stacking cones?

It depends on the type of stacking cone and the construction of the containers, but typically, up to 6–8 containers can be stacked on top of each other.

Are stacking cones mandatory for container transport on ships?

Yes, for safety and compliance with international standards, stacking cones or alternative devices are mandatory.
