Where can the safe working load of a rigging block be found?

The safe working load (SWL) of a rigging block is typically marked directly on the block itself. This is done to ensure that operators and riggers can easily identify the load capacity at a glance, promoting safety and compliance in lifting operations. This labeling is crucial for preventing overload situations, which can lead to catastrophic failures.

Having this information clearly visible on the rigging equipment helps establish safe practices on-site, as it provides immediate access to vital load information without requiring additional resources or references. While other sources may contain this information, such as rigging manuals or documentation from signal persons, the most immediate and reliable source for the SWL of a specific block is the block itself.
