Quick chain link, Grade 8 – screw-type, galvanized, 350 kg load capacity

Chain connecting links are used to connect chains and other lifting accessories. To ensure safe handling, the following instructions must be observed:

1. Intended Application and Suitability

• Chain connecting links are designed only for static and approved connection applications. They must not be used for safety-critical purposes or lifting operations unless expressly approved for such use.
• Observe the Working Load Limit (WLL) and grade classification appropriate for the respective chain type and load.
• Only use with chains and accessories of the same grade (e.g. Grade 8).

2. Before Use

• Visual inspection: Before each use, inspect the chain connecting link for damage such as cracks, deformation, corrosion or signs of material fatigue.
• Thread and fastening: Ensure that the thread is clean and free from damage. The locking screw must be capable of being fully tightened.
• Check compatibility: Verify that the connecting link is suitable for the chain size and the lifting accessories being used.

3. Use

• Correct assembly: The connecting link must be fully and correctly tightened. The locking screw must not loosen during use.
• Observe the loading direction: Chain connecting links must only be loaded in the intended direction and must not be subjected to side loading or cross-loading.
• No overloading: The maximum Working Load Limit (WLL) must never be exceeded.
• Operating conditions: Ensure that the connecting link is not damaged by external influences during use (e.g. impacts or abrasion).

4. Special Conditions

• Environmental influences: Depending on the material specification, connecting links may be suitable for use in damp, chemically aggressive or temperature-critical environments. Select the material according to the application conditions (e.g. galvanised steel or stainless steel).
• Temperature range: Observe the recommended operating temperature range of the material, as extreme heat or cold may affect its performance and strength.

5. Maintenance and Care

• Clean the connecting link regularly, particularly the threaded section, to prevent wear and corrosion.
• Replace damaged connecting links or locking screws immediately.
• Lubricate moving parts (e.g. the locking screw) when necessary to ensure smooth operation.

6. Storage

• Store connecting links in a clean and dry environment, protected from corrosion, moisture and mechanical damage.
• Before storage, ensure that the connecting link is fully assembled and free from damage.
• Avoid contact with aggressive chemicals that could attack the material.

7. Additional Information

• Connecting links are not intended to be permanent or safety-critical connections. They should be inspected regularly for condition and safe operation.
• Do not use connecting links for lifting or securing applications unless they have been specifically approved for such use.
• Do not modify the connecting link in any way (e.g. cutting, drilling or welding).
• If there is any uncertainty regarding suitability or special application requirements, consult the manufacturer or a qualified specialist.
