How to lift a shipping container safely and efficiently?

February 17, 2023

Shipping containers play a vital role in the global trade industry, and ensuring their safe and efficient lifting is crucial. Whether you're relocating a container or preparing it for maritime transport, mastering proper lifting techniques is essential to protect workers and avoid damage to the container. In this article, we'll explore various methods for lifting shipping containers safely and effectively, with a particular emphasis on container lifting as the main topic. Beyond slings, another option for lifting shipping containers is the use of automatic lifting hooks. These hooks are specifically designed to securely and efficiently hoist containers, minimizing the need for manual labor and reducing the risk of accidents and injuries.

Automatic release hooks operate by attaching to the top corner castings of the container and then lifting it using a crane. These hooks can be controlled remotely, enhancing safety by keeping workers at a safe distance from the container during the lifting process. Moreover, automatic crane hooks can be adjusted to accommodate containers of varying sizes and weights, making them a flexible solution for lifting different types of containers and loads.

Lifting with Gantry Cranes

Gantry cranes are among the most common lifting equipment used for shipping containers due to their versatility in handling containers of various sizes and weights. There are two main types of cranes used for container lifting: mobile cranes and gantry cranes. Mobile cranes are highly adaptable and can move around the job site, making them ideal for loading and unloading containers from trucks and ships. Gantry cranes, on the other hand, are stationary and typically found in ports or shipyards.

 

Alternative Methods for Lifting a Sea Container

There are several methods for lifting shipping containers, including forklifts, cranes, and hydraulic lift systems. Each method has its own set of advantages and limitations, and the choice of method depends on factors such as the container's weight, dimensions, and the specific conditions of the lifting area. Here are some of the most widely used methods for container lifting:

Forklift Trucks

Forklifts are a popular choice for lifting smaller shipping containers or moving them within confined spaces. Forklifts have a maximum lifting capacity of 45,000 pounds, making them suitable for handling small to medium-sized containers. To lift a container with a forklift, the operator inserts the forks into the corner castings and raises the forks to elevate the container off the ground.

Hydraulic Lift Systems

Hydraulic lift systems are a common choice for lifting shipping containers, especially in shipyards and container terminals. These systems use a series of hydraulic cylinders to raise the container off the ground, allowing for easy movement and transportation.

Container Lifting Jacks

Container lifting jacks are indispensable tools for safely and efficiently lifting shipping containers. When using container lifting jacks, it’s important to take appropriate safety precautions to ensure a successful and secure lift.

What Type of Slings Are Recommended?

Using the appropriate lifting slings is critical when lifting shipping containers to ensure safety and efficiency. The right type of sling not only helps you lift the container without causing damage but also prevents accidents and injuries. Here are some recommended types of slings for lifting shipping containers:

1. Steel Cable Slings: Steel cable slings are one of the most versatile and popular types of slings for lifting shipping containers. They are strong and durable, and their flexibility makes them suitable for a wide range of lifting applications. Steel cable slings can be used in both vertical and horizontal lifts and are often the preferred choice for lifting heavy containers.
2. Chain Slings: Chain slings are another popular type of sling for lifting shipping containers. They are incredibly strong and capable of handling heavy loads, making them an excellent choice for lifting larger containers. Chain slings can be used in both vertical and horizontal lifts and are often used in combination with spreader bars to distribute the load more evenly.
3. Synthetic Slings: Synthetic slings are lightweight and easy to handle, making them a great option for smaller containers or when lifting containers in tight spaces. They are also resistant to corrosion and can be used in harsh environments. Synthetic slings are available in various materials, including nylon, polyester, and high-performance fibers like Dyneema.
4. Flat Web Slings: Flat web slings are made from nylon or polyester and are ideal for lifting smaller shipping containers. They are lightweight and easy to handle, and their flexibility allows them to conform to the shape of the container. Flat web slings are also resistant to abrasion and have a high strength-to-weight ratio.

When selecting slings for lifting shipping containers, it’s essential to consider the container’s weight and dimensions, as well as the lifting environment. It’s also crucial to follow the manufacturer’s instructions for use and inspect the slings before each lift to ensure they are in good condition. By choosing the right type of sling and using it correctly, you can lift shipping containers safely and efficiently.
