Tsurikawa in a car: purpose, operating principle and application features

If you've ever been faced with the need to tow a car or carry cargo on a roof, then the word "tsurikawa" should be familiar to you. Literally translated as "suspension rope" or "tension strap," this Japanese term in the automotive industry refers to a system of fastenings that securely secures loads, trailers, or even the vehicle itself during recovery. But in practice, a tsurikawa is much more than just a belt with hooks.

In this article we will look at what it is Tsurikawa from a technical point of view, where it is used (from tow ropes to securing luggage), how to choose and use it correctly, as well as what mistakes car owners most often make. We will pay special attention Japanese safety standards, which are often stricter than European ones, and we will explain why tsurikawa has become an integral part of the equipment of many cars in Asia and is now being actively introduced in Russia.

You will learn how tsurikawa differs from conventional tow ropes, what loads it can withstand, and why it is often confused with kinbaku (Japanese art of rope bondage) - spoiler: there is a connection, but only in the name. We will also reveal One little-known fact: Tsurikawa can save your car from serious damage in an accident if used for its intended purpose..

What is tsurikawa: definition and origin of the term

The term "Tsurikawa"(Japanese, tsurikawa) literally translates as “suspension belt” or “tension loop”. It was originally used in Japan to refer to handrails on public transport (such as trains or buses) that passengers hold on to while moving. However, in the automotive industry, this word has taken on a different meaning.

In the context of machines Tsurikawa is a fastening system that includes:

• 🔗 Cables or belts made of high-strength materials (polyester, nylon, steel fibers).
• 🔒 Carabiners and hooks with safety locks to prevent unintentional release.
• 📏 Adjustment elements (tensioners, ties) to control tension.
• 🛡️ Shock absorbing inserts (in some models) to dampen jerks.

Interestingly, in Japan tsurikawa is regulated by the standard JIS D 9401, which defines the minimum requirements for the strength and reliability of fastenings. For example, a class tow rope Tsurikawa Grade 1 must withstand a load of at least 3,000 kg without breaking. In Europe, similar requirements are described in the standard DIN 74054, but Japanese manufacturers often exceed these standards.

⚠️ Attention: Don't confuse Tsurikawa with kinbaku - Japanese art of aesthetic bonding. Despite the similarity of names, these are completely different things. Tsurikawa in a car is purely a technical fixture and not a decorative element.

Where is tsurikawa used: 5 main areas of use

Tsurikawa is universal, but most often it is used in the following cases:

1. Towing cars. Unlike conventional cables, tsurikawa ensures even load distribution and prevents jerking that could damage the body or suspension.
2. Securing cargo on the roof. For example, bicycles, skis or luggage boxes. Here tsurikawa acts as an alternative to railings.
3. Fixing trailers and trailers. This is especially true for passenger trailers, where standard coupling devices do not always provide sufficient rigidity.
4. Evacuation and transportation. When loading a car onto a tow truck, the tsurikawa is used for insurance so that the car does not move off the platform.
5. Sports events. In rally or drifting, tsurikawa is used to quickly evacuate cars from the track.

In Japan, tsurikawa is often included as standard equipment on new cars (especially SUVs and pickup trucks). In Russia it is usually purchased separately, but its popularity is growing due to its reliability and ease of use.

How Tsurikawa works: principle of operation and device

The main advantage of tsurikawa over traditional cables is dynamic load distribution. Let's look at how this works using the example of towing:

1. Fastening. One end of the tsurikawa clings to the towing eye of the leading vehicle, the other - to the eye of the towed vehicle. Carabiners with locks are used to prevent spontaneous disconnection.
2. Tension. Using an adjusting mechanism (usually a screw or lever), the cable is tensioned until the slack is eliminated. This prevents jerking when starting to move.
3. Depreciation. Some models have elastic inserts that dampen vibrations. This is especially important when towing long distances.
4. Control. While driving, the tsurikawa maintains constant tension, which reduces the risk of breakage or damage to the body.

By comparison, a regular tow rope does not have a tension system, so during sudden braking or starting, it can jerk, causing damage to the bumper or towbar.

Parameter	Tsurikawa	Regular tow rope
Maximum load	3,000–8,000 kg	1,500–3,000 kg
Availability of depreciation	Yes (most models)	No
Tension adjustment	Yes	No
Self-release protection	Yes (locks on carabiners)	No
Service life	5–10 years (with proper care)	2–5 years

⚠️ Attention: If you use a tsurikawa to secure roof loads, be sure to check the tension every 50–100 km. Vibration and wind can weaken the fastening, leading to loss of cargo.

How to choose a tsurikawa: key criteria

When purchasing a tsurikawa, pay attention to the following parameters:

• 🏋️ Load capacity. It must exceed the weight of your vehicle or cargo by at least 30%. For example, for a car weighing 1,500 kg you need a cable with a load of at least 2,000 kg.
• 🧵 Material. The best option is polyester reinforced with steel threads. It is stronger than nylon and does not rust.
• 🔗 Mounting type. Carabiners must be made of hardened steel with an automatic lock. Avoid plastic latches!
• 📏 Length Usually enough for towing 4–6 meters. For securing loads on the roof - 2–3 meters.
• 🛡️ Availability of a certificate. Check compliance with standards JIS D 9401 or DIN 74054.

Popular brands include:

• 🇯🇵 Yokohama Rubber is a Japanese manufacturer specializing in high-load cables.
• 🇩🇪 Thule - Known for luggage mounts, including tsurikawa roof mounts.
• 🇺🇸 Curt Manufacturing — Offers universal towing kits.

Step-by-step instructions: how to use tsurikawa correctly

Let's look at the process using the example of towing a car:

1. Preparation. Make sure both vehicles are on level ground and the handbrake of the towed vehicle is released (if it is in neutral).
2. Fastening.
   • Attach one end of the tsurikawa to the towing eye of the lead vehicle.
   • Secure the other end to the eye of the towed car. Use both hooks (if available) to distribute the load evenly.

Tension. Using the adjusting mechanism, tighten the cable so that it does not sag, but is not too tight. The optimal tension is when the cable springs slightly when pressed by hand.

Check. Before starting to move, check the reliability of the fastenings and the absence of twists in the cable.

Movement. Start moving smoothly, without jerking. The speed should not exceed 50 km/h.

For securing cargo on the roof, the algorithm is similar, but with some nuances:

• Use the bare minimum 4 attachment points (two on each side of the load).
• Cover the load with a tarp if it can move in the wind.
• Check the tension every 50 km.

Common mistakes when using tsurikawa and how to avoid them

Even experienced car owners sometimes make mistakes that can lead to accidents or damage to the car. Here are the most common of them:

• 🚫 Using a worn cable. Tsurikawa, like any consumable material, has a service life. If the cable has abrasions, breaks or corrosion on the carabiners, replace it.
• 🚫 Incorrect tension. Too little tension leads to jerking, too much tension leads to deformation of the fasteners.
• 🚫 Fastening to unintended elements. Never catch your tsurikawa on the bumper, suspension or plastic parts. Only for special eyes!
• 🚫 Ignoring weight restrictions. If the load capacity of the cable 3,000 kg, and your car weighs 3,500 kg, the risk of breakage is extremely high.
• 🚫 No safety rope. When towing, always use an additional safety rope in case the main one breaks.

One of the most dangerous mistakes is towing a car with locked wheels (for example, if the car is in “parking” or with the handbrake on). This could result in transmission damage or even fire due to overheating of the brake pads.

What happens if you interrupt towing by sudden braking?

If the leading vehicle brakes sharply, the towed vehicle will continue to move forward by inertia. If the tsurikawa does not have shock absorbers, the cable may break, which will lead to:

• 💥 Damage to the bumper or hitch.
• 🚗 Displacement of the towed vehicle (up to rollover).
• 🔥 Breaking the cable and injuring others.

This is why it is important to use a tsurikawa with shock-absorbing inserts and maintain smooth movement.

Tsurikawa vs alternative fastening methods: which is better?

Many car owners are wondering: is it worth buying a tsurikava if there are cheaper alternatives? Let's compare:

Mounting method	Benefits	Disadvantages	Cost
Tsurikawa	✅ High strength ✅ Shock absorption ✅ Versatility ✅ Long service life	❌ High price ❌ Requires fastening skills	3 000–10 000 ₽
Regular tow rope	✅ Low price ✅ Easy to use	❌ No depreciation ❌ Risk of breakage ❌ Short service life	500–2 000 ₽
Chain	✅ Very durable ✅ Suitable for heavy loads	❌ Heavy ❌ May damage the body ❌ Inconvenient to store	2 000–5 000 ₽
Belts with hooks	✅ Lungs ✅ Compact	❌ Low load capacity ❌ Not suitable for towing	300–1 500 ₽

As can be seen from the table, tsurikawa is golden mean between reliability and convenience. It is more expensive than a regular cable, but cheaper than professional chains, while providing better protection against jerks and damage.

FAQ: Frequently asked questions about Tsurikawa

Can a Tsurikawa be used to tow a car with an automatic transmission?

Yes, but with reservations. Most automatic transmission vehicles can be towed in neutral, however:

• The speed should not exceed 30–50 km/h (check the instructions for your model).
• Towing distance is usually limited 50–100 km.
• If the box is damaged, towing may be prohibited - in this case, a tow truck is needed.

Always check your vehicle's manual before towing!

How to store tsurikawa to make it last longer?

Follow a few simple rules:

• Store the rope in a dry place, away from direct sunlight (UV radiation destroys polyester).
• After use, clean off any dirt and sand that may damage the fibers.
• Do not store the cable in a twisted state - this may deform its structure.
• Periodically check the carabiners for corrosion and lubricate them.

With proper care, Tsurikawa will last 5–10 years.

How is tsurikawa different from slings?

Although both terms refer to fasteners, there are key differences between them:

• Slings - These are usually flat belts made of synthetic materials designed for lifting loads (for example, in cranes). They do not have tension adjustment or carabiners.
• Tsurikawa is a system with tensioners, shock absorbers and reliable fastenings designed for dynamic loads (towing, transportation).

Simply put, slings are used for static lifting, and tsurikawa are used for movement.

Is it possible to make tsurikawa with your own hands?

Technically yes, but highly not recommended. Homemade cables:

• Not certified according to standards JIS or DIN.
• May have hidden defects (for example, uneven fiber weaving).
• They are not equipped with shock absorbers and reliable carabiners.

If the cable breaks at speed, the consequences can be catastrophic. It's better not to skimp on security.

Where to buy quality tsurikawa?

You can purchase certified tsurikawa:

• In specialized auto stores (for example, AutoSpetsCenter, IXORA).
• On marketplaces (but check reviews and certificates!).
• From official dealers of Japanese brands (for example, Yokohama or Thule).

The cost depends on the carrying capacity and brand: from 3 000 ₽ for budget models up to 15 000 ₽ for professional kits.
