There are several reasons why the lashing chain on a vehicle should not be used for lifting purposes:
Load Rating:
- Lashing chains are typically designed and rated for securing and restraining cargo during transportation, not for lifting loads.
- The working load limit (WLL) or safe working load (SWL) of lashing chains is usually much lower than the WLL/SWL of chains and accessories specifically designed for lifting applications.
- Using a lashing chain for lifting can easily exceed its load capacity, leading to a potential failure and risk of injury or damage.
Chain Quality and Certification:
- Lashing chains may not be manufactured to the same high-quality standards and testing requirements as lifting chains.
- Lifting chains are often made from higher-grade materials and undergo more rigorous quality control and certification processes to ensure their safety and reliability for lifting operations.
Wear and Damage:
- Lashing chains are typically subjected to different types of wear and damage during transportation, such as abrasion, impact, and exposure to the elements.
- These factors can compromise the integrity and strength of the chain, making it unsuitable for lifting loads, as the reduced strength may not be visually apparent.
Lifting Attachments:
- Lashing chains may not have the appropriate lifting attachments, such as correctly sized and rated hooks, links, or other fittings, necessary for safe and secure lifting.
- Using improvised or unsuitable attachments can introduce additional risks and weaknesses to the lifting system.
Regulations and Best Practices:
- In many jurisdictions, the use of lashing chains for lifting is prohibited or strongly discouraged by safety regulations and industry best practices.
- Specialized lifting chains, slings, and accessories are designed and approved for lifting operations to ensure the safety of workers and the integrity of the load being lifted.
To ensure the safety of personnel and equipment, it is critical to use only the appropriate lifting accessories and equipment that are specifically designed, certified, and rated for lifting applications. Attempting to use lashing chains for lifting purposes can be extremely dangerous and should be avoided.
