Maximum loads and other ratings shown in this website are applicable only to new or “in as new” condition products. Merchandise not marked with “Maximum Load” are non-load rated applications only and should not be used in critical lifting or tension situations.
Maximum load indicates the greatest load a product can carry under normal conditions. Factors that will reduce the load capacity include shock loads, acceleration of the load, product damage, twisting, knotting, kinking, corrosion, elongation, or damage of any type to the product making it in less than a “new condition”. Any product that is damaged should be immediately withdrawn from service and permanently discarded in a manner to insure that the product will not be used again.
Maximum loads are based on data from manufacturers and their products. Maximum loads are determined on a design factor ratio of the minimum breaking strength if the product is in new condition. Design factors set by the Cordage Institute vary from 5 – 12 for non-critical applications. Because of the infinite number of cordage constructions, materials, uses, and conditions, it is not realistic or possible to make a standard blanket maximum load recommendation. Maximum loads published in our website or catalogs are applied to rope in a new condition and under non-critical applications, with normal service conditions. Normal service is generally considered to be use under minimal dynamic or mild static load conditions. Never exceed the maximum load.
Rope recoils in an oscillating, unpredictable path, away from the point of failure with great impact. Never allow anyone to stand in line or alongside a rope under tension. If the rope fails, serious damage, injury, or death may result from the recoil of the rope or from any parts or attachments.
Select your rope and any connecting hardware specific for the use and conditions. Match all components to maximum loads. Inspect rope and its components on a regular basis. Take any product showing cuts, worn, frayed lengths, or any other deformation out of service.
Design factors should only be selected with expert knowledge of use and conditions.
Rope will last longer under proper care, storage, and use. Please keep safety foremost in your mind when using any product. Misuse of any product may result in damage to property, injury, or death.
