Load securing during transportation faces many challenges, especially when dealing with loads that have sharp edges. The sharp edges pose a risk to the integrity of lashing equipment and can potentially lead to accidents, jeopardising the safety of vehicle occupants and other road users. Hence, understanding the potential dangers associated with sharp edges is critical to ensure safe and efficient transportation. Read Part 2 below.
Reduction of Lashing Capacity
With loads where the lashing chain goes over sharp edges, we recommend reducing the Lashing Capacity (LC) by 25% or using a larger chain size. The Load Restraint Guide 2018 of the National Transport Commission (NTC) outlines the rules for lashing loads with sharp edges.
For example, if a lashing chain has a rated capacity of 10,000 daN, the effective securing capacity with a sharp corner load would be reduced by 25%, to 7500 daN.
ICE Grade 120 Lashing Chains
ICE Grade 120 lashing chain can replace a Grade 80 lashing chain of the next largest nominal thickness in direct lashing. ICE 120 is lighter than Grade 80 by 45% and has a breaking force up to 60% higher than Grade 80. This means that using an ICE 120 lashing chain can result in a large weight reduction, easier assembly, and better safety.
How can Endless Chains help?
In situations where suitable lashing points are unavailable or the existing points are unsuitable, using hooks or shackles for connecting the lashing chain can expose the connecting element to bending stresses. This can compromise the integrity of the connection and lead to potential failure.
Endless chains, designed to eliminate the need for separate hooks or shackles, provide a safer alternative. With an endless chain, the lashing capacity remains consistent throughout the entire chain loop, eliminating the potential weak points associated with hooks or shackles. Moreover, doubling up an endless chain reduces the effects of sharp edges, as the load is distributed across a larger surface area, which limits the stress on individual chain links.
ICE-Endless-Chain and ICE-Multi-shortening Claw
When combined with the ICE-Endless Chain, the ICE-Multi-shortening claw forms a closed chain system that is easily adjustable and can be opened without tools. This flexibility allows for convenient use in situations where the load's dimensions may vary. This configuration is particularly beneficial for securing loads with unconventional shapes, such as stone blocks or concrete, which may lack dedicated lashing points.
The advantages of such a configuration are:
Conclusion:
Understanding and addressing the challenges posed by sharp edges during load securing is crucial for ensuring safe and efficient transportation. By implementing the guidelines of the Load Restraint Guide and utilising appropriate protective measures such as edge protectors and endless chains, we can effectively mitigate the risks associated with sharp edges, ensuring the integrity of the lashing equipment and the safety of all road users.
