If you're new to ratchet straps, you might come across terms like "Minimum Breaking Force" (MBF) and "Lashing Capacity" (LC). Understanding these terms is essential for safely securing loads. Here's a simple explanation to help you get started:
What is Minimum Breaking Force (MBF)?
The Minimum Breaking Force (MBF) refers to the point at which your ratchet strap will break when it is subjected to force. It's essentially the maximum load your strap can handle before failing. Manufacturers test their straps rigorously to determine this breaking point, ensuring that they meet safety standards. It's important to remember, however, that MBF represents the absolute breaking limit—not the working limit—so your ratchet straps should never be used at their full MBF.
What is Lashing Capacity (LC)?
Lashing Capacity (LC) is different from MBF, and it’s actually the most critical factor to consider when using ratchet straps. The LC indicates the maximum force your ratchet strap is safely rated for during normal use. Think of LC as the safe workload limit that keeps your loads secure without risking strap failure. This value is always lower than the MBF to ensure you have a safe margin for error.
Why does it matter?
Understanding MBF and LC is crucial because it helps you choose the right ratchet straps for your job, ensuring your load is secure and safe during transit. For example, if you're transporting heavy furniture, you should always use ratchet straps with a sufficient LC to handle the weight and stresses of the journey.
Always make sure your straps clearly display both MBF and LC ratings and remember to choose straps with an LC rating suitable for your load. By paying attention to these details, you'll help prevent accidents and protect your cargo and other road users.
