Such breaks can cause loads to fail or swing out of control, possibly resulting in serious injury or death as well as major property damage.
Therefore:

• Never exceed the Working Load Limit (WLL).
• Match components properly.
• Keep out from under a raised load.
• Avoid shock loads.
• Inspect products regularly.

Breaking Strength/Ultimate Strength

Do not use breaking strength (breaking load) as a criterion for service or design purposes. Refer to the Working Load Limit instead.
Breaking Strength is the average force at which the product, in the condition it would leave the factory, has been found by representative testing to break, when a constantly increasing force is applied in direct line to the product at a uniform rate of speed on a standard pull testing machine. Proof testing to twice the Working Load Limit does not apply to hand-spliced slings.

Remember: Breaking Strengths, when published, were obtained under controlled laboratory conditions. Listing of the Breaking Strength does not mean the Working Load Limit should ever be exceeded.

Regular Inspections

Inspect products regularly for visible damage, cracks, wear, elongation, rust, etc. Protect all products from corrosion. The need for periodic inspections cannot be overemphasized. No product can keep operating at its rated capacity indefinitely. Periodic inspections help determine when to replace a product and reduce rigging hazards. Keep inspection records to help pinpoint problems and to ensure periodic inspection intervals.
Due to the diversity of the products and uses to which they can be put, it would be counterproductive to make blanket recommendations for inspection procedures and frequency. Best results will be achieved when qualified personnel base their decisions on information from rigging and engineering manuals and on experience from actual use in the field.
Frequency of inspection will depend on environmental conditions, application, storage or product prior to use, frequency of use, etc. When in doubt, inspect products prior to each use. Carefully check each item for wear, deformation, cracks or elongation - a sure sign of imminent failure. Immediately withdraw such items from service.
Rust damage is another potential hazard. When in doubt about the extent of corrosion or other damage, withdraw the items from service.
Destroy, rather than discard, items that have been judged defective. They might be used again by someone not aware of the hazard involved.

General Definitions

Information contained in this catalog is subject to change; all weights and dimensions are approximate. Ratings are stated in short tons (2,000 lbs.) or pounds. All dimensions are in inches; all weights are in pounds, unless stated otherwise.

Working Load Limit

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 conditions and consideration must be given to unusual conditions such as extreme high or low temperatures, chemical solutions or vapors, prolonged immersion in salt water, etc. Such conditions or high-risk applications may necessitate reducing the Working Load Limit.

Proof Test Load (Proof Load)

The term "Proof Test" designates a quality control test applied to the product for the sole purpose of detecting defects in material or manufacture. The Proof Test Load (usually twice the Working Load Limit) is the load which the product withstood without deformation when new and under laboratory test conditions. A constantly increasing force is applied in direct line to the product at a uniform rate of speed on a standard pull testing machine.

The Proof Test Load does not mean the Working Load Limit should ever be exceeded.

Design Factor (sometimes referred to as safety factor)

An industry term usually computed by dividing the catalog Breaking Strength by the catalog Working Load Limit and generally expressed as a ratio. For example: 6 to 1.

Shock Load

A load resulting from rapid change of movement, such as impacting, jerking or swinging of a static load is referred to as shock load. Sudden release of tension is another form of shock loading. Shock loads are generally significantly greater than static loads. Any shock loading must be considered when selecting the item for use in a system. Avoid shock loads as they may exceed the Working Load Limit.

Wire Rope & Cable

WIRE ROPE IS A MACHINE. Understand and respect it.
Like any machine, it needs proper care and maintenance for optimal safety and long service life. For a better understanding of wire rope, we highly recommend the Wire Rope User's Manual by the Wire Rope Technical Board.

Cable Puller General Warnings

Failure to understand and follow these warnings and instructions could result in property damage, serious personal injury or loss of life. Use of this product demonstrates an understanding of these warnings / instructions and the risks involved. Below is a list of general warnings.

• DO NOT EXCEED RATED CAPACITY for pulling or lifting.
• Do not use for overhead lifting. Do not lift any material above shoulder height. Keep all persons clear of load while suspended. Never allow persons beneath a suspended load.
• Cable pullers are not designed for cargo tie down or load measurement. They are not approved for use as such by any government agency.
• Inspect puller and its components prior to each use. Do not use if any part of the cable puller is visually damaged.
• Never use handle extensions (cheater bars).
• Do not use puller around sharp corners as this may damage the cable, greatly reducing strength.
• Never load the hooks on the tips of the hook.
• Do not use if the cable is kinked or knotted.
