How to Prepare Rigging Operations for Extreme Environments: Materials and Lubrication Choices
Extreme environments can damage rigging equipment through heat, chemicals, corrosion, impact, and constant motion. Preparing rigging operations for those conditions requires choosing the right materials, protecting that equipment from the elements, and maintaining it to prevent premature failure and ensure safe lifts. Recognize Environmental Stressors Many factors influence the service life of a wire rope . Many of them, such as load and duty cycle, are present in every application. In extreme environments, hazards can come from every direction. Heat: High ambient temperatures or proximity to welding arcs, furnaces, or exhaust systems can degrade synthetic fibers and alter the metallurgical properties of steel wire. Chemicals and salt: Acids, alkalis, solvents, and salt water attack protective finishes and the base metal. Synthetic fibers can absorb chemicals, while steel components corrode in the presence of salt and moisture unless properly lubricated. Abrasion: Sand, dirt, a...
