Rigging hardware and commercial chain are commonly used in various industries for lifting, rigging, and securing heavy loads. Here's a brief overview of each:
Rigging Hardware: Rigging hardware refers to a wide range of components used in lifting and rigging operations. These components are designed to connect, secure, and control loads. Some common types of rigging hardware include:
- Shackles: As mentioned earlier, shackles are U-shaped metal pieces with pins or bolts across the opening. They are used to connect and secure various objects.
- Hooks: Hooks are curved or bent metal devices used for grabbing, holding, and suspending loads. There are different types of hooks, such as eye hooks, clevis hooks, and grab hooks, each serving specific purposes.
- Turnbuckles: Turnbuckles are adjustable tensioning devices with two threaded ends and a body in the middle. They are used to create tension or length adjustment in wire rope, cables, or chains.
- Eyebolts and Eye Nuts: These are bolts and nuts with a circular loop or "eye" at the end. They provide a secure anchor point for attaching lifting devices or connecting loads.
- Wire Rope Clips: Wire rope clips are used to clamp two ends of a wire rope together or create a termination point. They consist of a saddle, U-bolt, and nuts.
Commercial Chain: Commercial chains are durable and robust chains commonly used in industrial applications for lifting, towing, and securing loads. They come in various grades, sizes, and configurations to accommodate different load capacities and working conditions. Some common types of commercial chains include:
- Grade 30 Chains: Grade 30 chains, also known as proof coil chains, are general-purpose chains used for lighter loads and applications such as towing, logging, and agriculture.
- Grade 43 Chains: Grade 43 chains, also known as high test chains, have higher tensile strength than Grade 30 chains. They are commonly used in load binding, transportation, and construction applications.
- Grade 70 Chains: Grade 70 chains, also known as transport chains, are specifically designed for load securement in the transportation industry. They have a higher tensile strength than Grade 43 chains.
It's important to select the appropriate rigging hardware and commercial chain based on the specific requirements of your application, including load capacity, working load limits, material compatibility, and industry standards. Always follow safety guidelines, regulations, and manufacturer recommendations for proper use, inspection, and maintenance of these components.
