Which type of chain is the only OSHA approved chain for overhead lifting?

The correct answer is alloy chain, which is recognized as the only type of chain approved by OSHA for overhead lifting. Alloy chains are specifically designed to handle high-stress applications and have enhanced properties that make them suitable for lifting heavy loads. They are manufactured to meet rigorous standards regarding strength and durability, which is essential for the safety of overhead lifting operations.

Alloy chains are produced using high-quality materials that undergo processes to improve their mechanical properties. This includes processes that enhance tensile strength and overall performance in lifting scenarios, making them vastly superior for applications where safety is paramount.

While proof coil chain, transport chain, and high test chain may have their uses, they do not meet the strict safety standards set forth by OSHA for overhead lifting. Proof coil chains, for example, are generally used for securing loads and may not hold up safely under the stress of lifting. High test chains, while stronger than standard proof coil chains, also do not undergo the same level of testing and certification that alloy chains do.

Therefore, alloy chain is specifically engineered for the demands of overhead lifting, ensuring compliance with safety regulations and minimizing the risks associated with lifting operations.
