Types of damages you should look for in tie downs: Hope this helps!
When inspecting tie down transportation straps, look for damage like: holes, tears, knots, broken stitching, embedded particles, burns, caustic burns, abrasion, UV degradation, cracks or corrosion on fittings, unusual wear patterns at contact points with the fitting, melted or charred areas, and signs of excessive wear or elongation on the webbing itself.
Key points to check:
- Webbing damage: Cuts, tears, abrasions, snags, embedded materials, excessive wear, melting or charring, color fading from UV exposure
- Stitching issues: Broken or loose stitching, unraveling threads
- Fitting damage: Cracks, pits, corrosion, weld splatter on hooks, ratchets, and cam buckles
- Chemical damage: Burns from acids or alkalis
- Unusual wear patterns: Areas where the webbing is excessively worn due to contact with a fitting
- Missing information: Check if the working load limit (WLL) is visible and legible on the tag
Do not use a tie down strap if you find any significant signs of damage.
1. Ultraviolet (UV) Damage
The top strap remains undamaged by UV exposure, while the lower strap has faded from a vibrant yellow to a pale shade due to prolonged UV exposure. It’s important to note that UV damage can occur even on cloudy days, without direct sunlight. Therefore, it’s essential to store straps properly, away from the elements, to prevent such deterioration.
2. Snag
The polyester fibers have snagged on a foreign object, broken, and separated from the webbing structure.
3. Knot
The webbing twists upon itself as a result of intentional knotting, improper storage, or inadequate collection of loose webbing during transit. When knotted, the strap’s strength is compromised.
4. Embedded Object
A foreign object, such as a shard of glass or piece of metal, becomes lodged between the fibers of the webbing..
5. Crushed
Occurs when an extremely heavy object or load severely compresses the webbing, leading to its distortion.
6. Cut
Damage to the webbing caused by acute or prolonged abrasion against a sharp object..
7. Caustic Burn
Occurs when chemicals or acidic fluids interact with the polyester, resulting in its melting.
8. Burns
Happens when the polyester strap is exposed to a hot object for an extended duration or when intense sunlight remains focused on a specific spot for a prolonged period
9. Broken Thread
When the thread in the sewn part of the webbing breaks, it compromises the integrity of the straps, which are crucial for maintaining their strength under pressure
10. Abrasion
Happens when the strap continuously rubs against another object over an extended period
