Working Load Limit
The Working Load Limit or Safe Working Load is the maximum load which should ever be applied to the product under any condition. The Working Load Limit is based on a load being uniformly applied in a straight line pull.
Do NOT use Breaking Strength for design or rating purposes. Use the Working Load Limit instead. Breaking Strength is an average figure at which samples have been found to break under laboratory conditions in straight line pulls with constantly increasing loads. These conditions are rarely duplicated in actual use. The Breaking Strength applies to new and unused wire rod for Wire Rope, Aircraft Cable, and Chain.
The load a product can withstand during quality control test for the purpose of detecting defects and deformation in the material, usually twice the Working Load Limit.
All attachments used with chain and wire rope must be of suitable material, type and strength to provide adequate safety protection. Attachments should have Working Load Limits at least equal to the other components with which they are used.
No product can operate indefinitely at its rated capacity. Cable, wire rope, chain, and their attachments must be inspected regularly by a trained or qualified individual for visible damage, distortion, elongation, corrosion, cracks, nicks, or abrasion, which may cause failure or reduce the strength or ability of the product to perform safely.
Loads which exceed the static caused by a rapid change of movement, such as jerking, impacting, or swinging of load. Working Load Limits will not apply.
The US Customs law requires that the end user of imported products be informed of the country of origin. All imported products sold by Cargo Control USA are marked accordingly. Re-sellers are responsible to relay this country of origin information to the end user.
General Warnings & Cautions
All products supplied and manufactured by Cargo Control USA are sold with the express understanding that the purchaser is thoroughly familiar with the safe and proper use and application of the product.
Responsibility for the use and application of the products rests with the user.
Failure of the product can occur due to misapplication, abuse, or improper maintenance. Product failure could allow the load to become out of control, resulting in possible property damage, personal injury or death.
There are numerous government and industry standards that cover products sold by Cargo Control USA. This catalog makes no attempt to reference all of them. We do reference the standards that are most frequently asked about. Ratings shown in Cargo Control USA literature are applicable only to new or “in as new” condition products. Load limit ratings indicate the greatest force or load a product can carry under usual environmental conditions. Shock loading and extraordinary conditions must be taken into account when selecting products for use in a system.
In general, the products displayed in Cargo Control USA literature are used as parts of a system being employed to accomplish a task. Therefore, we can only recommend within the Working Load Limits, or other stated limitations, the use of products for this purpose.
The Working Load Limit, or Design Factor, or Efficiency Rating of each Cargo Control USA-supplied product may be affected by wear, misuse, overloading, corrosion, deformation, intentional alteration, and other use conditions. Regular inspection must be conducted to determine whether use can be continued at the catalog assigned WLL, a reduced WLL, or whether the product must be withdrawn from service.
Cargo Control USA products generally are intended for tension or pull. Side loading must be avoided, as it exerts additional force or loading which the product is not designed to accommodate.
Welding Cargo Control USA-supplied load support parts or products can be hazardous. Knowledge of materials, heat treatment, and welding procedures are necessary for proper welding. Cargo Control USA should be consulted for information.
The assigned Ultimate Load Rating of Cargo Control USA-supplied products for the reeving of wire, manila, or synthetic ropes is based upon design; the catalog ultimate strength for the rope parts, when totaled, may exceed the assigned Ultimate Load Rating.
The Working Load Limit of a sling must not exceed the lowest Working Load Limit of the components in the system.
