What is the primary reason rigging hardware should NOT be modified?

The primary reason rigging hardware should not be modified is that such modifications could negatively affect its capacity. Rigging hardware is designed and manufactured to precise specifications that ensure it can safely bear certain loads. Any alterations, whether through welding, cutting, or adding components, can compromise the integrity and structural strength of the equipment. This alteration may lead to an unexpected failure under load, posing serious safety risks to personnel and equipment.

When hardware is modified, the original load rating might no longer apply, and there is no guarantee that the modified hardware will behave as expected under stress. Maintaining the original design and specifications of rigging hardware is crucial for ensuring safety and reliability during lifting operations. Therefore, it's vital to adhere to manufacturer guidelines and standards without making unauthorized changes.
