Spreader Beam Capacity Chart
Typical WLL and span guide for Multisec modular spreader beams.
A spreader beam capacity chart shows the typical Working Load Limit and maximum span for different spreader beam models.
It helps engineers and lifting professionals compare beam sizes, identify a suitable modular spreader beam configuration and understand how WLL, span and sling arrangement affect beam selection.
Final beam selection should always be confirmed against the approved configuration, sling arrangement and certified engineering calculations.

How to Use a Spreader Beam Capacity Chart
To use a spreader beam capacity chart, first identify the required Working Load Limit, then compare the available span for each model.
Start with the Load Weight
The required WLL should exceed the total load, including the lifted item and any rigging used in the lifting arrangement.
Check the Required Span
Span is the distance between lifting points. As span increases, the available capacity of many spreader beam systems can reduce.
Review Sling Angles
Sling angle directly affects the forces within the lifting system. Final selection should account for the approved sling arrangement.
Choosing the Right Spreader Beam Capacity
Capacity is only one part of beam selection. The final configuration should also consider load geometry, lifting points, headroom, environment and project requirements.
Spreader Beam vs Lifting Beam Capacity
Spreader beams work primarily in compression and are typically used where there is sufficient headroom. They help control sling angles and maintain load stability during lifting.
Lifting beams are more commonly used where headroom is restricted, with the load suspended from a central lifting point beneath the beam.
