Key Points for Secure Steel Chain Binding

1. Three Key Steps for Hooking

* Hook Tongue Facing Outwards, Not Inwards: Ensure the hook tongue faces outwards when hooking (inwards, it's easy to slip off).
* Only Hook at Solid Anchor Points: Welded iron rings, equipment base holes—avoid hooking water pipes/thin iron sheets.
* After Hooking, Lightly Tap to Test: Gently tap the back of the hook with a small hammer; a crisp echo means it's securely hooked, a dull sound means it's not properly secured.

2. steel chain Winding Anti-Loosening Techniques

* Wind Two Full Turns, Leaving Extra Links: Wind the steel chain around the goods two full turns, leaving 3-4 extra links.
* Reverse Insertion of the Tail Link: Thread the excess steel chain link backwards into the third link hole (like fastening a seatbelt pin).
* Add a Safety Wedge: Hammer a triangular wedge into the gap between the steel chain links (paint the wedge head to mark the position).

3. Tips to Prevent Breakage

* Leave a Buffer Ring: Leave a basketball-sized empty ring in the middle of the steel chain (don't straighten it, it cushions the impact).
* Buffer Ring Size Reference: Approximately the diameter of a truck tire (too small is ineffective, too large is cumbersome).

4. Pitfalls to Avoid:

Edge Protection: Pad sharp edges of goods with rubber sheets or old tire linings (to prevent abrasion) -** (to prevent abrasion)
Do Not Mix New and Old steel chains: Old steel chains may have hidden damage; store them separately and do not splice them.
Wear Thick Gloves in Low Temperatures: When operating below -10℃, wear oil-soaked suede gloves to prevent frostbite.

5. Safety Inspection Methods

Listen to the Sound to Determine Condition: → Tap the steel chain link with a small hammer; a crisp "ding" sound = normal → a dull "plop" sound = possible cracks (stop using and inspect)
Simple Crack Check: After cleaning the steel chain, apply chalk dust—dark, fine lines appearing indicate a potential crack.
