Ratchet Strap Strengths and Sizes

Ratchet straps are the ideal strap for securing a load onto a plane, trailer, truck or any other hauling vehicle. The ratchet design results in a tighter, more secure fit than other designs such as the cam. The ratchet straps itself is made from synthetic webbing that makes them weatherproof in even the most extreme of conditions. They come equipped with several different kinds of connecting hardware such as flat, snap or wire hooks, chain extensions or connectors for e-track or airline track, to name a few.

When choosing the right ratchet strap, it is important to consider the weight of the load that is to be secured as this will determine what strength of strap is appropriate. The width of the strap is the main factor which will determine the strap's load capacity. Ratchet straps are available in 1-inch, 2-inch, 3-inch, and 4-inch widths – the wider the strap, the stronger. The type of connector a strap uses for securing to an anchor point will also factor in the overall strength of the strap.

Each ratchet strap will be given a strength measurement which must comply with various US and international standards; these will be the break strength and work load limit. It is important when calculating the required strength of the strap to understand the difference between the two. The break strength is the weight at which the strap or overall assembly will actually give way and break – it is NOT the limit of how much weight the strap can actually carry – that is determined by the work load limit. The safe work load limit is approximately 1/3 of the break strength and, for safety, this limit should never be exceeded.

Understanding the importance of calculating the necessary strength of ratchet straps required for an individual job is paramount to completing the delivery safely. By following the 1/3 rule for the work load limit, optimum safety can be ensured.
