How to Read a Crane Load Chart

It’s essential that operational training form part of your warehouse maintenance every year. 

Many people assume that warehouse maintenance is solely about repairing physical equipment. However, offering safety and equipment training to your staff is just as essential. This refreshes everyone’s skills and can help improve productivity at the ground level. 

Cranes and forklifts are some of the most popular warehouse equipment options within the logistics industry. While these machines are great for lifting and moving heavy items around, it’s essential that your staff understands how to read crane load charts. This will ensure that you maximize productivity while remaining safe and efficient. 

Interested in learning more about load charts for cranes? You’re in the right place. Here’s what you need to know about reading crane load charts. 

Different Kinds of Cranes

Cranes have been around for thousands of years. While ancient trains may have looked and operated completely differently, they still relied on the same core principles of leverage. Currently, we have a wide variety of cranes that can help with numerous different tasks. 

The best way to distinguish the various cranes is by looking closely at their uses. Some cranes are used outdoors for construction while others are used indoors for logistics. 

Each kind of crane comes with its own pros and cons. Outdoor cranes tend to be more mobile and flexible. This means that you can quickly assemble it on a construction site, or move the crane from one location to another. 

On the other hand, indoor cranes like overhead cranes and bridge cranes are ideal for warehouses and loading yards. This is because they are incredibly efficient and reliable for repetitive operations.

How to Read a Crane Load Chart

Whether you have an outdoor construction crane or an indoor warehouse crane, it’s important to know how to read a crane load chart. Understanding how to read one will not just keep your warehouse efficient, it will also keep everyone safe. Here’s a quick look at how to read a crane load chart.

What Is a Crane Load Chart?

A crane load chart is a simple document that highlights the lifting capabilities of a particular crane. This chart is designed specifically for cranes and will let you know how much it can lift depending on its position, extension, and base.

This chart is incredibly important to help crane operators and warehouse managers handle the crane. Attempting to lift something that exceeds the crane’s capabilities can be dangerous for everyone in the warehouse. 

What Does a Crane Load Chart Look Like? 

A crane load chart is a detailed chart that starts with outlining the measurements of the crane. This is particularly important for mobile cranes that need to safely navigate tight spaces. 

The next part of the chart is a table that outlines everything you need to know. The charts use gross capacities while the maximum load that the crane can lift is known as the net capacity. In simple terms, you should always make sure that the items you’re lifting never exceed the net capacity of the crane. 

Capacity deductions are made to calculate the net capacity of a crane. These deductions can vary from manufacturer to manufacturer. These deductions tend to include the weight of the load block,  the effective weight of the jib, and the weight of all rigging. 

Once these deductions are made, you will be able to find out what the net capacity is for your exact crane. This is the weight that you should never exceed when using the crane.

Various Capacities and Combinations

When you take a closer look at the load chart, you will notice that there are numbers along the x-axis and the y-axis. The numbers along the x-axis are along the top row and indicate the boom length of the crane. The numbers along the y-axis are down the first row and indicate the operating radius. 

The chart will then clearly indicate what the gross capacity is for the crane at any given boom length and radius combination. 

Load Chart Regulations

When it comes to operating a crane, there are a few things that you should always keep in mind. Firstly, it’s important that your crane operator has all the necessary licenses before they start using the crane. In addition to this, it’s vital that they understand the exact crane that they’re using.

As mentioned above, not all cranes are the same. Cranes come in all shapes and sizes, with some more powerful than others. This means that different cranes come with varying lift capabilities.

This is why reading the crane load chart is so important. This essential piece of information will help them prepare before taking over the crane. 

Understanding the load chart is so important that it’s actually an OSHA requirement. This makes it abundantly clear that everyone operating or working with cranes should be able to see and know exactly how to read the crane load chart.

Understanding Crane Charts

When it comes to operating cranes, understanding crane load charts is incredibly important. While this chart may look different from crane to crane, they serve the same essential purpose. This lets you know how much load you can safely lift and move.
