Understanding Load Charts – The Key to Safe and Efficient Lifting

Load Charts in Crane Lifts

At Premier Cranes, we know that success in the lifting game isn’t just about having the best cranes—it’s about mastering the details.


One crucial aspect that operators and planners alike must get right is understanding crane load charts.

These charts are essential tools that guide the safe and efficient use of cranes, helping us deliver on our promise of seamless and secure lifting operations.


While computer simulations and in-cab indicators assist during lifts, the real strength comes from the operator’s ability to read and interpret load charts accurately.


These charts provide all the information needed about a crane’s lifting capacity, helping us stay on top of safety and protect both our crew and equipment.


At the end of the day, a good load chart tells you what your crane can—and can’t—do.

Avoiding Common Mistakes with Load Charts

At Premier, we pride ourselves on attention to detail.

Here are some common pitfalls to watch out for when working with load charts:

  1. Ignoring Crane Configuration
    • Every lift is different, and so is every crane setup. 
    • Things like counterweight amount and outrigger extension can make or break your lift plan.
    • Forgetting these details might lead to overloading or instability, which is why we always tailor our configuration for each lift to ensure the best results.
  2. Overlooking Load Radius
    • The load radius—the horizontal distance between the crane’s centre pin and the load—affects lifting capacity. 
    • The further the reach, the less weight the crane can handle.
    • It’s important to factor this in when selecting a crane to make sure it can handle the load at the required radius.
  3. Misinterpreting Boom Angle and Length
    • Getting the boom angle or length wrong can result in a miscalculated lift. 
    • Precise interpretation of these details is critical to ensuring the load stays within safe limits.
  4. Forgetting Accessory Weights
    • Items like rigging gear, the hook block, or a fly jib must be deducted from the total lifting capacity.
    • Overlooking these small but important details could lead to overloading the crane.
  5. Disregarding Stability Factors
    • A crane’s stability is key to a successful lift. 
    • Factors such as boom angle, extension, and counterweight distribution all play a role. 
    • If they aren’t calculated correctly, there’s a risk of tipping or overturning.
  6. Neglecting Ground Angle
    • Load charts are based on the crane being perfectly level. 
    • Even a slight tilt (as little as three degrees) can reduce capacity by up to 50%! 
    • Understanding the terrain and adjusting for ground slope is essential for safe operation.

Premier Takes Safety Seriously

At Premier Cranes, we don’t just lift; we lift smart. 

Load charts are a crucial part of that strategy. 

They provide the data we need to make informed, safe decisions—especially when combined with our expertise and the latest technology. 

Remember, these charts don’t account for everything—environmental factors like wind and ground conditions can change the game quickly.

All of our crane operators are certified professionals with proven industry experience who are trained to the highest standards – They are reliable, adhere to all OHS site requirements, and follow strict operating guidelines

At the same time, they are flexible enough to work around specific site conditions to get the job done safely. #TeamLifting

Explore Our Load Charts for Each Crane

We have made sure that every crane we offer is supported with detailed load charts that are readily accessible.

These charts provide clear insights into the lifting capacities of each crane, taking into account different configurations, load radius, and boom lengths.

This allows project managers, site planners, and operators to choose the right crane for the job with complete confidence.

For more details, you can also explore the load charts we’ve added for each crane on our website’s crane pages.

This resource ensures you are equipped with all the technical information you need to make well-informed decisions before your lift.

Whether you’re planning a lift for a tight urban site or a wide-open infrastructure project, you’ll find the precise capabilities of our cranes clearly outlined.
