Cut Risk VS Abrasion Risk
All materials can be cut if exposed to a certain pressure or sharp edges. The textile fibres used to make slings (polyester, HMPE, para-aramid) have excellent tenacity that makes them very resistant to traction. However, if exposed to contact with uneven surfaces, they are destined to wear out or cut, generating enormous implications for safety.
Today, the same textile fibres, with which slings are made to lift very heavy loads, also allow for the creation of adequate protections to prevent the following risks of damage:
■ Cut risk: the sling is in contact with sharp edges or corners (for example a steel beam or a forged piece). In these circumstances, the
sling can be seriously damaged, even cut, even on the first use.
Protections against the risk of cut are made of HMPE fibre or Dyneema®. They must cover the entire surface of the sling that comes into contact with the load and prevent the load from cutting or penetrating the structure of the sling. They comply with the European standard EN1492-2 (“Reinforcements and protection against damage caused by edges and/or abrasion”).
■ Abrasion risk: the sling is in contact with rough or uneven surfaces (for example a concrete structure). In these circumstances, the sling, constantly subjected to abrasion from the load, is likely to be seriously damaged and even cut.
Abrasion protections are made of robust and durable materials. They cover the entire surface of the sling that comes into contact with the load. Thanks to the wide range, it is possible to protect any type of sling (flat and round slings).
Different types of risks require in-depth assessments to identify the best solutions for safety.
Begni Group has gained significant experience in the heavy lifting sector (large forgings, jumbo coils, slabs, structural beams), where the risk of cutting must be assessed with skill and with reliable solutions.

WARNING
Protections bad used od damaged compromise the safety during the lifting operations.
Inspect the protections before the use and verify there are no cuts or tears.
Choose the protection of the right size, to cover the maximum width of the sling.
Avoid the protection and the sling can slip or move across the load edge.
MAX LOAD: don’t exceed the maximum weight of 4000 kg per cm of the sling width.
