- Working load limit: 55t ~2000t.
- Materials of shackle body and pin are processed through quenching and tempering with high-quality alloy steel.
- Proof testing load: twice 55t~300t
- 1.5 times 400t
- 1.33 times 500t~ 2000t
- The minimum breaking load is 4 times of the rating working load.
- Manufacturing method of the shackle body: die forging combined with free forging technique.
- Both circular and hexagonal nuts are available.
- Non-destructive flaw detection is employed for every single product to ensure there is no intensity defect.
- Each shackle will be marked with working load.
- no need to use the thimble when the shackle was connected with high-strength lifting belt, wire rope sling and large radius’s domed roof. Wear-resisting property of the wire rope sling is improved obviously.
- The shackle body and the pin are galvanized and then the pin paint in blue.
- Blue pin is the quality mark of Juli original product.
- At present shackles used widely are made of alloy steel instead of carbon steel in the past.
- International standard shackles include shackles for lifting, shackles for ship and ordinary shackles.
- Shackles with big weight and volume are usually installed where seldom disassembled.
- Safety factor (usually there are 4:1,6:1 and 8:1 available) is an important point when choosing shackles.
- We must use the shackles according to their Wll. Overuse and overload are both forbidden.
- Shackles widely used in market include Chinese standard, American standard and Japanese standard.
- American standard shackles are used more because of small volume and big capacity.
- According to different type, American standard shackles include G209(BW), G210(DW), G2130(BX), G2150(DX); According to different using occasions, American standard shackles include shackles for ship and shackles used on land.
- For safety factor, there are 4:1, 5:1, 6:1 and even 8:1.
- For the raw material, there are carbon steel, alloy steel, stainless steel, high-strength steel etc.
- For the treatment, there are galvanizing (include hot-dip galvanizing and electro galvanizing), painting and Dacormet available.
