Hercules’ Tips: Prevent Synthetic Round Sling Damage

roundsling

We’ve discussed what to look for when assessing your synthetic round sling for damage—but how do you prevent damage from happening in the first place?

Read on for essential tips to prolong the life of your synthetic round slings.

Round Sling

First and foremost, you should avoid activities that cause chemical burns, bunching, tears or exposed yarns. To prevent damage to your round sling, refrain from:

  • Dropping or dragging it along the ground or rough surfaces;
  • Pulling slings from under loads when load is resting on the sling—place blocks under load if possible;
  • Shortening or adjusting the sling using unapproved methods;
  • Twisting or knotting the sling;
  • Exposing sling to damaging alkali’s or acids;
  • Exposing sling to sources of heat damage or weld splatter;
  • Using slings or allowing exposure to temperatures above 194° (90°C) or below -40°F (-40°C).
  • “Tip Loading” a sling on a hook rather than centering it in base, or “bowl” of the hook;
  • Using hooks, shackles or other hardware that have edges or other rough surfaces which could damage the sling;
  •  Running/driving over sling with a vehicle or other equipment.

In addition to these factors, exposing synthetic slings to certain chemicals can cause minor or total degradation—time, temperature and concentration factors affect degradation. Consult your sling’s manufacturer for specific applications.

Sharp Edges and your Sling

One of the most crucial aspects of protecting your sling is ensuring it’s kept away from sharp edges. It’s important to note that edges or surfaces in contact with your sling don’t have to be “razor” sharp to cause sling failure. Slings can be damaged, worn down or even torn as tension between your sling, connection points and cargo develops.

Protect damage to your sling from corners, protrusions or contact with any edge that isn’t rounded or smooth. To do so, a qualified person will determine appropriate methods for protecting the sling in relation to the conditions it will be used in. The qualified person may use specially developed protectors like sleeves, wear pads or corner protectors to shield the sling from harsh edges.

Conducting lift tests (in a non-consequence setting) is recommended to test your safe-guarding methods—remember to inspect your sling after each lift test for damage and suitability.

Can my Sling Ever Touch Edges?

Avoid your sling directly contacting edges, unless the edge is:

  • Smooth and well-rounded;
  • The size of the radii is adequately large. Use the table below (Image 1) to determine the minimum edge radii suitable for contact with synthetic slings.

Prevent further damage to your sling by storing it in a clean, dry and dark place. Use mild soap and water to wash your sling, and never place it in the washing machine. Avoid storing somewhere your sling may be exposed to acids or other harmful chemicals or splatters.

Overall, even when following every safeguard described above things may go wrong. Be sure to asses your load properly, never place any part of your body between yourself and the sling, and always ensure all personnel are clear from lifted or suspended loads.

Synthetic Roundslings – Free Inspection Download Guide

roundsling

Synthetic roundslings are an integral part of heavy-lifting and rigging. Similarly, proper sling inspection is integral to ensure the job is done safely and properly.

Read on to find out how to inspect your roundslings for use.

Look and Feel for Damage

Most damage to a roundsling can be found simply by looking. However, internal damage can be present as well. Inspect for internal damage by feeling along the slings’ entire length.

Minor Damage Causes Major Incidents  

Damage to a roundsling may seem minor or small, yet this can drastically reduce its ability to lift or hold heavy loads.  This increases its risk of breaking during use−which can result in large costs, damaged material and most importantly, injured people.

In reality, no damage to a roundsling is minor−if damage is present, it should not be used.

What Should Operators Look and Feel for?

–        Missing Identification tag;

–        Holes, cuts, tears, snags that expose core yarn, excessive abrasive wear;

–        Broken or damaged yarn core;

–        One or more knots are tied to roundsling;

–        Acid or caustic burns of roundsling;

–        Melting, charring or weld spatter of any part of roundsling;

–        Distortion, excessive pitting, corrosion or other damages to fitting(s);

–        Broken or worn stitching in the cover which exposes the core yarn;

–        Any conditions that cause you to doubt the roundslings’ strength.

I’ve Found Damage−Now What?

If any damage is found, pictured above or otherwise, the sling must be removed from service. When removed, the sling must be completely destroyed, and must be made unusable for future use. If it’s repairable, it must be proof-tested by the roundsling’s manufacturer or another qualified tester.

 

Frayed Sling

 

Sling damage should never be temporarily repaired.

Synthetic roundslings are an integral part of heavy-lifting and rigging−however, proper inspection is also necessary to ensure the job is done safely, and properly. Keep reading to find out how often to assess your roundslings before use.

Inspections—how often should I do this?

Roundsling inspection should use the following 3-step procedure, which ensures slings are inspected frequently enough. The stages are:

Initial Inspection

When your sling is received, a designated employee will ensure the correct sling has been received, is undamaged and that it meets requirements for use.

Frequent Inspection

The roundsling should be inspected before each shift, each day in normal service. When using for severe service application, the roundsling should be checked before each individual use.

Periodic Inspection

Every sling should be periodically inspected by a designated person. However, this inspection should be performed by someone who does not regularly inspect the sling. This provides an opportunity to find issues that previous inspections may have missed or overlooked.

Period inspections are based on how frequently used slings are, or how frequently you anticipate you will use them for. Other factors include the severity of conditions and what type of work the sling is used for. Inspections may also be based on slings used in the past under similar circumstances.

Generally, inspections should be done as follows:

  • Normal Service—yearly
  • Severe Service—monthly to quarterly
  • Special Service—as recommended by a qualified person

Intervals between inspection should never exceed one year. Written records are not required for frequent inspections, however written records should be kept. The WSTDA, RS-1 and ASME B30.9 require written record of the latest inspection.
