Shipping containers have become incredibly versatile, serving purposes beyond basic storage. From mobile offices to homes and cabins, these sea cans can be found everywhere. However, one crucial aspect that often gets overlooked is the need to ensure that the container is level. In this comprehensive guide, we will explore the importance of levelling shipping containers and the role container jacks play in achieving this. So, whether you’re a shipping container enthusiast or looking to convert one into a unique space, read on to discover everything you need to know about levelling shipping containers.

Why Levelling Matters

Maintaining a level container is essential for several reasons. Firstly, it prevents damage to your cargo and ensures that items inside the container remain secure during transportation. When a container is unlevelled, cargo can shift, causing boxes to break open and potentially damaging fragile items. Additionally, an unlevel container can also lead to door misalignment, making it difficult to open and close the doors properly. By keeping your container level, you can avoid these issues and ensure the safety and integrity of your cargo.

The Challenge of Levelling Shipping Containers

Levelling a shipping container may seem like a straightforward task, but it can be more challenging than it appears. The construction of a container does not provide adequate space to allow a traditional bottle jack to slide underneath. This limitation has posed a problem for many container owners in the past. However, thanks to innovative solutions like the Twist ‘N’ Jack Container Lifter from Container Modification World, levelling your container with a jack is now easier than ever.

Introducing the Twist ‘N’ Jack Container Lifter

The Twist ‘N’ Jack Container Lifter is a revolutionary adapter designed to facilitate corner jacking on both new and used sea cans, shipping container homes, and offices. This innovative product, available on Amazon, allows for easy and efficient levelling of shipping containers. Container Modification World has developed this lifter to address the challenges faced by container owners when trying to achieve proper levelling. With the Twist ‘N’ Jack Container Lifter, you can now level your container with ease and precision.

Different Types of Container Jacks

Container jacks come in various types, each serving a specific purpose. Let’s explore some of the different container jacks available in the market:

Shipping Container Adjustable Support Jacks

One popular type of container jack is the shipping container adjustable support jacks. These jacks offer the flexibility to adjust their height, allowing you to lift any side of the container by up to 5.5 inches. Despite their compact size, these support jacks provide incredible strength, ensuring the stability and levelness of your container.

Shipping Container Leveling Bottle Jacks

Another type of container jack is the shipping container leveling bottle jack. As the name suggests, these jacks are shaped like a bottle and are specifically designed for lifting heavy loads. With a steel lifting saddle engineered to securely lift up to 12 tons, these jacks offer the strength and stability needed to level your container effectively.

Shipping Container Leveling Boosters

If you’re looking for a solution to keep your container level for extended periods, shipping container leveling boosters are the way to go. These boosters are designed to fit into existing holes in your shipping container’s frame, providing continuous support and stability. By using leveling boosters, you can ensure that your container remains level even when placed on uneven surfaces.

Factors to Consider When Buying a Container Jack

When purchasing a container jack, there are several key factors to consider to ensure you make the right choice. Let’s explore these factors in detail:

Load Carrying Capacity

The load carrying capacity of the jack is a crucial consideration. It determines how much weight the jack can safely lift. Look for jacks that have a high load carrying capacity, preferably over 5 tons, as they can handle heavier containers and provide greater stability.

Range of Adjustment

The range of adjustment refers to how high a jack can lift a container. It’s important to choose a jack with a wide range of adjustment, as this will allow you to level your container effectively, even on uneven surfaces. Stronger jacks can lift containers over 5.5 inches, providing the flexibility you need to achieve optimal levelness.

Material Durability

The material used to manufacture the jack is another critical factor. Opt for jacks made from high-quality steel, as they offer durability and longevity. Cheaper jacks may be made from less durable materials, leading to potential breakdowns and the need for frequent replacements.

Overall Durability

In addition to the material used, consider the overall durability of the jack. Look for jacks with heavy-duty steel frames and durable rubber feet that can withstand the rigors of container lifting. If you anticipate working with heavier loads, choose a jack with an extra-strong base, wheels, and good bearings to ensure long-lasting performance.

Price and Manufacturer’s Reputation

While price is an important consideration, it shouldn’t be the sole determining factor. Compare prices of similar products and choose a jack that offers a good balance between quality and affordability. Additionally, research the reputation of the manufacturer to ensure they have a track record of producing reliable and high-quality container jacks.

Levelling Containers on Uneven Surfaces

Sometimes, you may need to level your shipping container on an uneven surface where traditional methods may not be feasible. In such cases, container jacks can provide the perfect solution. Here are some scenarios where container jacks excel:

Limited Space

Container jacks are ideal for lifting containers in narrow spaces where cranes or forklifts cannot easily maneuver. With a container jack, you can lift and level your container without the need for extensive machinery, making it a convenient option for tight spaces.

Long-Term Leveling

If you require long-term leveling of your container, container jacks like leveling boosters are perfect. These jacks lock into place and keep the container level for extended durations, ensuring the stability and safety of your container.

Uneven Ground

When dealing with uneven ground, container jacks provide a practical solution. By placing a jack under one or more corners of the container, you can elevate and level the container with the ground, creating a stable and balanced foundation.

Preparing the Surface for Container Levelling

To ensure optimal levelling and stability, it’s important to prepare the surface where your container will be placed. Here are some steps to follow to prevent any imbalance:

  1. Choose a Solid Surface: Sandy or soil surfaces are not suitable for long-term container placement. Prepare a concrete or paved surface to ensure stability and prevent shifting of the container.
  2. Avoid Slopes: Ensure that the surface is not sloped, as this can cause the contents of the container to shift from one side to the other, leading to load imbalance and potential damage.
  3. Clean the Surface: Before placing the container, clean the surface to remove any debris or stones that could affect the stability and leveling of the container. Additionally, check for any cracks in the surface that could open due to the weight of the container.


Levelling shipping containers is a crucial step to ensure the safety and integrity of your cargo, as well as the proper functioning of doors and overall stability. With the right container jack, such as the Twist ‘N’ Jack Container Lifter, achieving levelness becomes a simple and efficient process. Consider factors like load carrying capacity, range of adjustment, material durability, and overall jack durability when choosing the right jack for your needs. By following proper surface preparation techniques and utilizing container jacks, you can ensure that your shipping container is level and ready for any purpose, whether it’s storage, a mobile office, or a customized living space.
