Product Operate Guide
Load Capacity Check: Confirm that the shackle's rated load matches or exceeds the actual load. Never use a shackle with a rated load lower than the required weight.
Visual Inspection: Check for cracks, deformations, or excessive wear on the shackle body and pin. Ensure there are no signs of corrosion that could affect its performance.
Pin Condition: Verify that the pin moves freely and can be securely tightened. Do not use a shackle with a damaged or stuck pin.
Installation: Align the shackle with the connecting components (such as chains, hooks). Insert the pin fully into the shackle body and tighten it securely to prevent loosening during use.
Load Application: Ensure the load is evenly distributed on the shackle. Avoid applying a side load, as this can reduce the shackle's load-bearing capacity and cause damage.
Operation Monitoring: During lifting or pulling operations, keep a safe distance from the shackle. Continuously observe the shackle's condition for any signs of abnormal deformation or movement.
Removal: After use, loosen the pin and remove the shackle carefully. Avoid dropping or hitting the shackle to prevent damage.
Cleaning and Maintenance: Clean the shackle with a clean cloth to remove dirt and debris. For shackles used in harsh environments, apply a thin layer of lubricant to the pin to prevent corrosion.
Storage: Store the shackle in a dry, ventilated place. Avoid storing it with other heavy objects that could cause deformation. Classify and label shackles of different specifications for easy access next time.
