Nylon slings are an excellent form of lashing, since they are economical, easy to handle and have high tenacity. However, even the best tool has its limitations. There are some issues one may face while using nylon slings for an operation.
★ Prone to damage from the load
Nylon slings hold a possibility of getting cuts on the edges from loads with sharp edges. Although the sling is easy on the load, fastening it tightly causes damage from the load. Before reusing a nylon sling, it is important to check its edges for cuts and abrasions, which are more often than not likely to result from this type of damage.
★ Susceptibility to extreme conditions
Nylon strings are tolerant to industry condition to some extent, however, continuous exposure to high temperature, acids and UV light can reduce the durability of these slings. Damage from burns and high temperature is easily identifiable, due to a charred appearance. Acid damage can be recognized as burnt appearance near the edges, with a visible black outline caused by the burnt area. If the slings turn brown in color, it is damage caused by UV light, which means these slings are not safe to use anymore. Slings may also get corroded or sport a brittle appearance, from exposure to extreme industry conditions.
★ Needs to be adjusted properly
More than often, handlers knot nylon slings to adjust their length. This method of sling adjustment is more common than one can imagine. The problem with knotting nylon strings is that it reduces the tensile strength and harms the functionality drastically. A knotted string during transit is likely to cause damage, so tying knots is a big no-no. Only the buckles are to be used for adjusting its length, which may take only a few more seconds, but they ensure a safe operation.
★ Issues from overuse
Durability is affected when nylon slings are overused. Besides this, improper handling or the nature of the load can cause the stitching threads to come loose. An overused nylon sling can be easily recognized, as it would bear visible wear and tear, broken stitches, damaged eye, a puncture, etc. If any of these signs are visible, your decision of whether or not to use that sling should be clear.
Due to the above mentioned limitations of nylon slings, it is important to store these in moderately cool and dry conditions. A regular inspection should be conducted, even for the slings that are not in use for the current operation. It goes without saying that a sling must be inspected right before using it for a strapping operation. It is also helpful to clean the sling before and after each use.
