Fixing method of container with ratchet straps

In global trade and logistics transportation, the fixation of containerized cargo is the core link in ensuring transportation safety. Whether it is sea transportation, railroad transportation or road transportation, the displacement or collapse of goods in the container may lead to serious economic losses or even safety accidents. The Cargo Lashing belt as a container cargo fixed key tools, its selection and use of methods directly affect the transportation efficiency and risk control.

Why must use the Ratchet Straps to fix the container cargo?

1. Prevent the risk caused by cargo displacement

According to statistics, the world's annual transportation accidents caused by improper fixation of goods, more than 70% with the container cargo sliding related. Ship swaying in the course of sea transportation, road transportation, emergency braking or turning, the unfixed cargo may hit the box or shift, light damage to the goods, or cause the container to capsize.

2. Reduce cargo loss and insurance costs

Stable cargo fixation can significantly reduce the friction of collision during transportation, and avoid the breakage of commodity packaging or damage to the internal precision equipment. For cargo owners, this not only means a reduction in direct economic losses, but also a reduction in the rate of cargo damage to obtain better insurance rates.

3. Compliance with international transportation regulations

The International Maritime Organization (IMO) and the transportation departments of various countries have put forward clear specifications for the fixing of container cargo. For example, IMO Cargo Stowage and Tie-down Safety Code (CSS Code) requires the use of standardized tensioners to tie down the cargo, otherwise you may face the risk of fines or refusal of shipment.

Types of Ratchet Tie Down and applicable scenarios

1. Ratchet Lashing

Characteristics: operate the ratchet mechanism through the handle to tighten the strapping, which can precisely control the tension.

Applicable scenarios: heavy machinery, building materials, palletized goods and other fixed needs that require high tension.

2. Lever Lashing

Characteristics: fast tightening by lever principle, easy to operate but low tension.

Applicable scenes: lightweight goods or temporary reinforcement, such as daily necessities, textiles and so on.

3. Elastic Lashing

Characteristics: Built-in rubber or spring device can cushion the vibration and adjust the tension automatically.

Applicable scenes: fragile goods, electronic products and other goods sensitive to vibration.

4. Chain Lashing

Characteristics: It adopts metal chain and tensioner, which is corrosion-resistant, high-temperature-resistant and extremely strong.

Applicable scenes: chemical raw materials, high temperature metal products and other special environment transportation.

The correct use of Lashing Strap 6 steps

Evaluate cargo weight and center of gravity

Select the type and quantity of tensioner according to the cargo volume and weight distribution. For example, a single piece of cargo over 2 tons need to use at least 4 high strength ratchet straps.

Fixed Anchor Check

Ensure that the anchor points such as D-rings and ground hooks on the inner wall of the container are not corroded or deformed, so as to avoid fixing failure due to broken anchor points.

Strap angle and tension control

The angle between the straps and the cargo surface should be kept between 30°-60°**. Too large an angle will reduce the effective tension, too small may scratch the goods.

Symmetrical distribution of strap positions

Adopt a “cross strapping” or “ring strapping” strategy to balance the forces in all directions inside the container.

Tension Testing and Adjustment

Use a tensiometer to check the tension of the straps. The recommended tension value for marine environments is not less than 500 daN (approx. 500 kilograms of force).

Regular Inspection and Maintenance

Check the status of the straps every 8-12 hours during transportation and adjust the slack parts due to vibration in time.

Common mistakes and risk avoidance

Mistake 1: Over-reliance on filling materials

Problem: Only use foam, wooden boards, etc. to fill the gap, ignoring the core role of the tensioner.

Risk: Fillers may crumble in long-distance transportation, resulting in loss of support for the goods.

Solution: Adopt the dual fixing strategy of “filler + tensioner”.

Mistake 2: Mixing straps of different sizes

Problem: Combining old and new straps or tensioners made of different materials.

Risk: Uneven tension may cause a single strap to break under overload.

Solution: Use the same brand and model of tensioners for the same batch of goods.

Mistake 3: Ignoring environmental factors

Problem: Failure to use rust-resistant tensioners in hot or humid environments.

Risk: Rusting of metal parts, accelerated aging of plastic straps.

Solution: Marine priority to choose galvanized steel tensioner or polyester fiber moisture-proof strapping.

How to choose cost-effective Cargo Lashing Belts?

Certification standards: Choose products that have passed TUV certification or meet ISO 17712 tamper-proof standards.

Material comparison:

Steel tensioner: high strength, suitable for heavy cargo, but need rust-proof treatment.

Polyester straps: lightweight and corrosion-resistant, but easy to deteriorate in long-term exposure.

Supplier service: Prefer suppliers that provide technical guidance and after-sales maintenance, such as our products.
