1. Installation precautions
Pin installation: The pin must be fully inserted and tightened, fixed with an open pin or locking nut. The open pin should be fully opened to prevent detachment
2. Direction of force:
Ensure that the direction of force is consistent with the design direction of the release buckle, avoid lateral or torsional force, and use a balance beam when connecting multiple steel wire ropes
3. Daily inspection points
Inspection cycle: Check before each use, and conduct regular monthly inspections immediately after use in harsh environments
Inspection content: Check whether there are cracks or deformations in the body, whether the horizontal pin is loose or worn, whether the thread is damaged, whether there is corrosion or rust on the surface, and whether the split pin is intact
4. Scrap standard
When the following situations occur, the shackle must be immediately scrapped:
Scrap standard for the body: visible cracks, deformation exceeding 10% of the original size, wear exceeding 10% of the original size, severe corrosion, affecting strength
Scrap criteria for horizontal pins: thread damage or wear, bending deformation, excessive clearance with the body, and failure of the locking device

Q: Can D-type shackles and bow shaped shackles be used interchangeably?
A: It is not recommended to use interchangeably. D-type shackles are suitable for unidirectional loading, while bow shaped shackles are suitable for multi-directional loading. Interchangeable use may reduce the safety factor.
Q: Which is better, stainless steel or galvanized shackles?
A: There is no absolute good or bad, it mainly depends on the usage environment. Stainless steel is recommended for seawater environments, while galvanizing is more cost-effective for freshwater environments.
Q: Do shackles need regular lubrication?
A: Yes, it is recommended to lubricate the transverse pin threads every 3-6 months to ensure smooth disassembly.
Q: Can the shackle be welded and repaired?
A: Absolutely prohibited! Welding can alter material properties, reduce load-bearing capacity, and pose serious safety hazards.
