HOW TO INSPECT LIFTING SHACKLES (PART 1)
Shackles are important lifting accessories that are basically used to connect load to lifting appliances.
Hence, a thorough inspection is often required to ascertain the integrity of shackles.
Below is a step by step process to conducting a thorough examination of shackles.
Assess documentation such as declaration of conformity (DoC)/ Manufacturer certificate (MC) and any previous report as well as safe use instructions.
Examine markings, such as CE mark, manufacturer name, symbol or code, grade number, WLL/SWL,traceability code, pins with a diameter ≥ 13mm often marked with the grade number, manufacturer name, symbol or code and traceability code.
Thoroughly examine component parts, especially the body and pin. Ensure that there are no distortions and verify dimensions. Make sure the component parts are free of damage, excessive wear, corrosion and nicks/gouges or forging defects e.g. unfilled section, small cracks/folds at corners, scale pits, lapping etc.
Secure nut and split pin. Examine pin tolerances. Ensure the body and the pin are both same brand and type. Check component functionality. Functionality examination is required if the shackle is fitted with, for example, a locking clamp, spring release mechanism etc.
