Working Load Limit

Never exceed the Working Load Limit (WLL) Rated Capacity. The Working Load Limit is the maximum load which should ever be applied to the product, even when the product is new and when the load is uniformly applied-straight line pull only. Avoid side loading. All catalog ratings are based upon usual environmental condidtions, and consideration must be given to unusual conditions such as extreme high and low temeratures, chemical solutions or vapors, prolonged immersion in salt water, etc. Such conditions or high-risk applications may necessitate reducing the Working Load Limit. Working Load Limit will not apply if product has been welded or otherwise modified.

Matching of Components

Components must match. Make certain that components such as hooks, links or shackles etc. used with wire rope (or chain or cordage) are suitable material and strength to provide adequate safety protection. Attachments must be properly installed and have a Working Load Limit at least equal to the product witch they are used.

Raised Loads

Keep out from under a raised load. Take notice of the recommendation from the National Safety Council Accident Prevention Manual concerning all lifting operations:

"All employees working on cranes or hoists or assisting in hooking or arranging a load should be instructed to keep out from under the load. From a safety standpoint, one factor is paramount: Conduct all lifting operations in such a manner, that if there were an equipment failure, no personnel would be injured. This means keep out of the line of force of any load."
