INSTRUCTIONS & CAUTIONS
WORKING LOAD LIMITS: This is the maximum load (in pounds) a chain should ever handle, even when it’s new and the load is evenly distributed along a straight, untwisted length. The “working load limit” doesn’t reflect the load the chain could potentially endure if conditions like wear, twisting, misuse, overloading, or corrosion are introduced. These factors can reduce the chain’s strength, so regular inspections are crucial to ensure safety.
PROOF TEST: This is the load (in pounds) a chain undergoes before leaving the factory. The chain is tested under direct tension in a straight line at a consistent speed using a standard testing machine. The purpose of this test is to identify any material or manufacturing defects.
All Proof Coil (Grade 30), High Test (Grade 43), and Transport (Grade 70) chains are proof tested. When using attachments like hooks or rings, make sure they match the chain’s grade, type, and size for proper load-bearing performance.
GENERAL WARNING: Chains made from low and high carbon steel, along with weldless and welded options, are designed for pull or tension applications only. Do not use them for lifting or hoisting, especially in situations where failure could cause injury or damage. Avoid jerking or rapidly applying loads, as this can significantly increase stress on the chain.
