For the lifting hardware in the daily using , how to judge their safety performance ?

When it comes to the safety performance of lifting hardware used in daily operations, there are several key factors to consider:

1. Load Capacity and Ratings:

   • Verify that the working load limit (WLL) or safe working load (SWL) of the lifting hardware is clearly marked and exceeds the weight of the loads to be lifted by an appropriate safety factor (typically 3:1 to 5:1).
   • Ensure the combined capacity of all the lifting components (e.g., shackles, hooks, slings) can safely support the total load.

2. Condition and Wear:

   • Visually inspect the lifting hardware for any signs of damage, deformation, cracks, corrosion, or excessive wear before each use.
   • Pay close attention to high-stress areas, such as hooks, links, and attachment points.
   • Consult the manufacturer's recommendations for acceptable wear limits and replacement criteria.

3. Certification and Traceability:

   • Verify that the lifting hardware is certified to meet relevant industry standards (e.g., ASME, EN, ISO) and has the appropriate markings and documentation.
   • Ensure the hardware has a unique identification or serial number that allows for traceability and record-keeping.

4. Lubrication and Maintenance:

   • Maintain the lifting hardware according to the manufacturer's recommendations, including regular cleaning, lubrication, and proper storage.
   • Proper maintenance helps preserve the integrity and safe performance of the hardware.

5. Proper Usage and Handling:

   • Ensure the lifting hardware is used for its intended purpose and within its rated capacity.
   • Avoid practices that can compromise the safety of the hardware, such as side loading, shock loading, or using makeshift attachments.
   • Train personnel on the proper techniques for rigging, lifting, and handling the lifting hardware.

6. Periodic Inspection and Testing:

   • Establish a regular schedule for thorough inspections and, where applicable, proof testing of the lifting hardware.
   • This helps identify any issues or degradation in the hardware's performance before it becomes a safety concern.

By considering these factors and following the manufacturer's recommendations, you can effectively judge the safety performance of the lifting hardware used in daily operations and ensure the safety of your workers and the integrity of the loads being lifted.
