At DunLash, we offer a complete range of manual, pneumatic, and battery-operated lashing tensioners built for consistent performance and durability. Paired with our high-performance cargo lashing systems, they ensure your cargo remains secure throughout the supply chain.

What Is a Lashing Tensioner?

A lashing tensioner is a tool used to tighten lashing straps (often made of polyester or composite materials) around cargo. The goal is to apply the correct tension to the lashing system to prevent cargo movement during transport. This minimises the risk of damage, accidents, or violations of international cargo securing regulations (like the CTU Code). Whether for maritime, rail, or road transport, a tensioner is an essential part of any load securing toolkit.

Manual Lashing Tensioners 

Manual tensioners are ideal for operations where portability and simplicity are key. They allow tension to be applied manually in a quick and ergonomic way, with the highest pre-tension capabilities in the market. These tools are commonly used in situations where power sources are unavailable, or where operators need maximum control over the lashing process.

Pneumatic Tensioners 

When you need maximum tension with minimal effort, pneumatic tensioners are the go-to choice. Powered by compressed air, a pneumatic tensioner delivers fast, consistent tensioning with the push of a button. This makes them ideal for high-volume operations or heavy-duty applications; perfect for environments where speed and consistency are vital, such as container stuffing stations, warehouses, or export packing facilities.

Benefits of pneumatic tensioners

  • Industrial-grade steel casing
  • Hardened components for long service life
  • Push-button operation for ease of use
  • Highest pre-tension in the market
  • Reduced operator fatigue
  • Lightweight and ergonomic
  • CE-certified for safety and compliance

Battery Operated Tensioners

Modern cargo operations demand flexibility, speed, and reliability. The Cordstrap CBT 35 Battery Operated Tensioner delivers all three. Designed for use with heavy-duty polyester cargo strapping, this cutting-edge tool combines battery-powered convenience with maximum control and precision. This battery-powered lashing tensioner is ideal for mobile operations, container yards, or remote worksites where reliability matters.

Benefits of battery operated tensioners

  • Consistent and repeatable tensioning
  • Powerful and easy to handle
  • No need for power outlets or air compressors
  • Always ready to use with rechargeable battery
  • Lightweight, ergonomic, and robust
  • Minimises strain and increases productivity

Choosing the Right Lashing Tensioner for Your Needs

Our experts can help assess your cargo securing needs and recommend the best lashing tensioner for your operation. Selecting the correct cargo securing tensioner depends on:

  • Cargo type and weight
  • Lashing system used (e.g., composite strapping, woven polyester)
  • Frequency of use (manual for low volume, pneumatic or battery for high volume)
  • Working environment (availability of power, ergonomics, speed requirements)

Lashing Tensioner FAQs

What is the purpose of a lashing tensioner?

A lashing tensioner is used to apply and maintain tension in lashing straps to secure cargo during transport. It ensures that loads remain stable and do not shift, tip, or fall during movement.

What’s the difference between a manual and pneumatic tensioner?

Manual tensioners require physical effort from the operator and are ideal for low- to medium-volume applications. Pneumatic tensioners use compressed air to apply high tension quickly and with minimal effort—ideal for repetitive, heavy-duty tasks.

Is a battery-operated lashing tensioner better than a manual one?

Battery-operated tensioners provide the benefits of speed, consistency, and ease of use—especially in environments where power or air supply may be limited. They’re ideal for high-throughput operations.

What type of strapping can your lashing tensioners be used with?

Our tensioners are designed specifically for Cordstrap woven polyester and composite strapping, offering secure, shock-absorbent, and non-damaging restraint for a wide range of cargo types.
