How Are Ratchet Straps Tested?

In the UK, businesses and individuals must secure traveling goods by law. Ratchet straps are a convenient way to secure heavy loads on vehicles and are widely used. So, what are the benefits of using ratchet straps and how are they tested for LC (lashing capacity)?

Benefits of Ratchet Straps

Ratchet straps make the roads safer for all drivers. Unfortunately, thousands of accidents happen every year because of debris falling from vehicles carrying heavy loads. The idea of using ratchet straps is to stop this from happening.

Ratchet straps can secure extremely heavy goods which allow drivers to drive with more confidence. The safety of all roads is vastly improved by ratchet straps on heavy cargo vehicles.

Material Used For Ratchet Straps

Polyester webbing is used for making ratchet straps. This material is strong and durable, hence the ability to secure heavy loads on vehicles. The material has very little stretch in it so users can rest assured that the straps aren’t going to move.

In addition, ratchet straps are chemical and UV resistant so they aren’t easily damaged while out in the elements. When it comes to rain, this material won’t absorb water so you won’t find it covered in mildew or rotting like other materials.

How Are Ratchet Straps Tested?

Before using a ratchet strap, they need to be tested to calculate the lashing capacity, standard tension force, and elongation. Here’s what you need to know.

Lashing Capacity

The lashing capacity is the measurement of the maximum amount of force the ratchet strap can withhold before breaking. It is measured in deka-Newtons (daN) and you’ll be able to see the daN on the label. If your strap has a daN of 2000, it means it can secure a load of 4000 kgs.

Standard Tension Force

The standard tension force is another way to measure the strength of ratchet straps. STF refers to the tension force created when the ratchet strap is pulled tight. You’ll find the STF on the label along with the LC.

Knowing these measurements will help you to determine how many straps you need to secure a load.

Elongation

Again, the elongation percentage can be found on the label of your strap. The elongation is the maximum amount the strap can stretch when fully tightened. By law, this can reach a maximum of 7% but most straps will be an average of 4%.

Tie Down Angle

The angle at which the ratchet strap is tied down is essential for security. The angle should be no less than 90 degrees. Anything less than 90 degrees could diminish the effectiveness of the straps.

There are many aspects to testing ratchet straps and using them safely and securely. Be sure to always check the label to find out how each strap should be used before trying to secure any heavy loads.
