Ratchet straps, also known as lashing straps and tie-downs, are one of the most popular methods for securing cargo, especially when it comes to shipping. Therefore, much like wire rope slings, they are an important component to material handling.
As with all industrial material handling equipment, you must take proper care of tie-down straps to use them both safely and effectively. Any kind of damage to your straps can affect both its working load limit and breaking strength, putting both equipment and individuals at risk.
Here are 5 top tips + 7 FAQs of ratchet strap safety you need to know.
1. Use Ratchet Straps Properly
The ratchet strap is absolutely a piece of extremely effective equipment to support many different weights and cargo sizes when used properly. However, our specialists have seen many cases that lashing straps damage very quickly and seriously because of misuse. Worse still, it can cause road hazards.
Thread ratchet straps
1. Insert the loose end of the heavy-duty lashing straps into mandrel of the ratchet (fig.1)
2. Pull the strap through the slot of the mandrel, and make the strap tight by removing any slacks (fig. 2)
3. Move the ratchet handle back and forth to tighten the webbing (fig.3)
4. Lock the handle down after tightening (fig.4)
Release ratchet straps
Step 1: Squeeze the webbing release bar
Step 2: Open the ratchet 180 degrees (fig. 1) for webbing removal
2. Keep Ratchet Straps Well Contained
Improper storage can lead to irreparable damage that can shorten the working life of your strap.
There are a number of tips and tricks for storing ratchet straps to keep them protected, including plastic freezer bags, duffel bags (store these inside a weatherproof box if left outside), rubber bands, and zip ties, for example. Rolling the straps and keeping them contained with one of these examples tends to be a good way to prevent multiple straps from getting tangled together that can certainly cause a headache if you need to spend an extended amount of time untying them.

Avoid Moisture
- Storing polyester straps where they are exposed to moisture runs the risk of mould and mildew. This can quickly become a serious problem for anyone storing their ratchet straps in the back of their truck, for example. Mould can extremely weaken the strength of the webbing (even heavy-duty ratchet straps) and the polyester can actually be destroyed in this way.
- Also, rainstorms or high humidity can over time form mould on your tie-downs. -
Avoid Direct Sunlight
Tie-down straps should always be stored in a dark, dry place away from the sun and moisture. When exposed to direct sunlight, tie-downs are subjected to harmful UV rays. If you notice colour fading, your straps are likely suffering from sunlight damage.
-
Avoid Friction and Heat
- When using tie-down straps during transport, you want to be careful that the straps don’t rub against a sharp edge or other objects. Such friction could damage the webbing by weakening it in spots (potentially causing rips and tears) or, if the friction is great enough, even create burn spots.
- Exposure to heat from additional sources, such as the sun, direct contact with fire, or another heat source can cause weakening issues with your tie-down straps.
- If you notice any burns in your straps, you need to cease use immediately and replace it with another strap with an equal working load limit.
3. Read the Label
Always prioritize ratchet strap safety!
Each ratchet strap comes with the coloured label that contains important safety information the user has to know before starting to secure the loads.
- Lashing Capacity(LC): This is measured in decaNewtons (daN), which are equivalent to kg. According to EN12195, LC is the maximum force for use in a straight pull that a web lashing is designed to sustain in use. Sometimes, the label shows an additional LC that is the lashing capacity in a round pull.
-
Standard Tension Force (STF): According to EN12195, it is the residual force after release of the handle of the ratchet. So, should STF or LC be the determining factor when it comes to lashing? Health & Safety Authority (HSA) states:
- When designing a direct restraint system, it is the lashing capacity (LC) to be the factor for determining the number of straps.
- When designing an indirect (frictional) restraint system, it is the STF, not the LC for the calculation of the number of straps needed
Can Ratchet Straps be Used for Lifting? NO, they cannot!
Our team has received many inquiries about lifting with ratchet straps. Let us explain this here. It is a lashing strap, but not a lifting sling. The safety factors for lifting equipment differ from those for lashing equipment, it is forbidden to use a lashing strap for lifting. That's why for safety reasons, the European Norm requires a statement like ''Not for lifting'' to be put on all lashing labels. -
GS (Geprüfte Sicherheit) Certificate
A certified testing company such as TUV is to test if a lashing strap complies with the EN 12195-2. If it does, a GS (Geprüfte Sicherheit) certificate will be given to allow the manufacturer to use the GS logo on the strap label. It ensures users that the ratchet strap is reliable and independently tested.
4. Get the Right Number of Ratchet Straps
If you're transporting palletised goods, boxes and stillages, you will need at least one strap per row according to the Health & Safety Authority. It is recommended that you use straps in pairs based on industry practice. If you're transporting logs in a truck fitted with a headboard, at least one strap per bay has to be used for the logs up to a maximum length of 3.3 metres with the bark still present. More information can be found in this guideline document (p.13-14).
