Lifting Accessories: Pre-Use Checks, Damage Detection, and Slinger Signaller Training
Lifting operations are a critical part of many industries, from construction and manufacturing to agricultural and warehousing. However, the safety and efficiency of these operations hinge on the correct selection, use, and maintenance of lifting accessories such as chains, slings, and shackles. Proper pre-use inspections are essential to prevent accidents, equipment damage, and costly downtime. Moreover, trained personnel, particularly those who have completed Slinger Signaller training, are indispensable for ensuring that lifting accessories are selected, attached, and used properly.
This blog will delve into the importance of pre-use checks, the types of damage to look for, the role of Slinger Signaller training in ensuring safety, and how Vally Plant Training can help you achieve the highest standards of lifting operations.
Types of Lifting Accessories
Lifting accessories are an integral part of many operations. Some of the most common types include:
- Chains: Used for heavy lifting operations.
- Slings: Available in different materials (wire rope, webbing, chain) for various applications.
- Shackles: Used to connect lifting equipment to loads or other lifting accessories.
- Hooks: Often found on cranes and hoists, used to connect to the load or other lifting accessories.
- Eye bolts and lifting points: These are fixed to the load to allow the attachment of lifting accessories.
- Lifting Beams and Spreaders: Used to distribute the load evenly.
Each accessory has its own specifications, limitations, and inspection requirements, making pre-use checks and proper training critical.
Pre-Use Checks for Lifting Accessories
Before any lifting operation, it’s essential to perform pre-use inspections to ensure that the accessories are in good condition and safe to use. Below is a guide on how to conduct these checks for common lifting accessories:
1. Chains
- Check for Wear and Elongation: Look for signs of wear, particularly in the chain links, where elongation or thinning may occur. A worn-out chain can snap under pressure.
- Inspect for Corrosion: Rust and corrosion weaken the chain’s integrity, especially in harsh environments.
- Look for Cracks or Nicks: Inspect for any visible cracks or damage, particularly at the weld points or link connections.
- Test the Chain for Flexibility: A stiff chain may indicate internal damage or corrosion.
2. Slings (Webbing, Wire Rope, Chain)
- Check for Fraying or Cuts (Webbing Slings): Inspect the fabric for tears, cuts, or fraying, which can compromise the sling’s strength.
- Inspect Wire Ropes for Kinks, Broken Strands, or Bird Caging: These are indicators of wear that can reduce the strength of the sling.
- Examine Chain Slings for Elongation or Wear: Similar to chain inspections, check for elongation and wear on the links.
- Check Identification Tags: Ensure the sling’s capacity is legible on its tag, as using an unidentified sling can lead to overloading.
3. Shackles
- Check for Distortion or Bent Pins: A bent pin or distorted body is a sign of overloading or improper use.
- Inspect for Corrosion or Cracks: Shackles exposed to the elements can corrode over time, leading to potential failure.
- Ensure the Pin Fits Properly: Loose or ill-fitting pins can cause the shackle to fail under load.
4. Hooks
- Check for Throat Opening: Ensure the hook’s opening has not widened, which could indicate overloading.
- Inspect for Wear and Cracks: Cracks or excessive wear on the hook body can lead to catastrophic failure.
- Test Safety Latch Functionality: Ensure the safety latch operates correctly and is not damaged or missing.
5. Eye Bolts and Lifting Points
- Inspect for Cracks or Deformation: Look for any visible signs of deformation, which may indicate overloading.
- Check Thread Integrity: Ensure that the threads are in good condition and can secure the bolt or point tightly.
What Damage to Look For
When inspecting lifting accessories, it’s crucial to identify and address specific types of damage that could compromise safety and functionality. Below are the common types of damage:
- Corrosion: Lifting accessories, especially those made of metal, are susceptible to rust and corrosion. This weakens the material, making it prone to failure during lifting operations.
- Cracks: Even small cracks in lifting accessories like shackles, chains, or hooks can lead to catastrophic failure, especially when they are subjected to high loads.
- Wear and Elongation: Over time, repeated use causes wear and elongation in chains, wire ropes, and slings. Elongated chains or worn-down slings are no longer safe to use.
- Fraying and Cuts: Webbing slings are especially prone to fraying or cuts from sharp edges. These slings should be immediately removed from service if they show any sign of such damage.
- Bent or Misaligned Components: Any bent or misaligned shackle, hook, or eye bolt is a red flag. This can indicate past overloading and should not be ignored.
The Role of Slinger Signaller Training
Lifting accessories can be dangerous if not used correctly. This is where the importance of Slinger Signaller training comes into play. A trained Slinger Signaller plays a vital role in:
- Selecting the Correct Lifting Accessories: Understanding load weight, centre of gravity, and sling angles ensures the correct accessories are chosen for the task.
- Attaching Accessories Properly: A Slinger Signaller is trained to attach chains, slings, and shackles in a way that ensures even load distribution and prevents slippage.
- Directing Lifting Operations: They communicate with crane operators to ensure smooth, safe movements during lifting, while also ensuring that the load is secure and balanced throughout the process.
