Important: Read Warnings Before Using this Website
It is of the utmost importance that anyone using this publication read and understand all warnings and other information listed below and/or adjacent to the product description and preceding each product section.
All Products are sold with the understanding that the purchaser is familiar with the correct application and safe use. Use all products properly, in safe manner and for the application for which they are intended. M&G assumes no responsibility for the use or misapplication of any product sold by this firm. Responsibility for design and use decisions rest with the user.
Remember: any product will break if abused, misused or overused. Any well-designed and well-built product can become hazardous in the hands of a careless user. Therefore:
- Never exceed the work load limit
- Match components properly
- Keep out from under a raised load
- Avoid shock loads
- Inspect products regularly
Work Load Limits
Never exceed the working load limit (WLL) and/or safe working load's (SWL) rated capacity. The WLL is the maximum load which should never be exceeded 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 high or low temperatures, chemical solutions or vapors, prolonged immersion in salt water, etc. Such conditions or high risk applications may necessitate reducing the work load capacity. Working load limits will not apply if product has been welded or otherwise modified.
Matching of components
Components must always match. Make certain that components such as hooks, links, shackles, etc., used with wire rope (or chain or cordage) are of suitable material and strength to provide adequate safety protection. Attachments must be properly installed and must have a WLL at least equal to the products with which they are used. Remember any chain is only as strong as its weakest link.
Always 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 at cranes or hoist 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 from under a raised load and keep out of the line of force of any load."
Avoid impacting, jerking or the swinging of a load — Work Load Limit will not apply. A shock load is generally significantly greater than the static load. Avoid shock loads and the sudden release of a load in order to avoid damaging the wire rope.
Inspect products regularly for visible damage, cracks, wear, elongation, rust, etc. Protect all products from corrosion. The need for periodic inspection, 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 insure periodic inspection intervals.
Due to the diversrity of the products involved 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 of product prior to use, frequency of use, whether or not life, limb or valuable property are at risk 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 by someone not aware of the hazard or the defect.
