When and Why to Use Twistlocks

A small component – a big difference in safety
In the container industry, twistlocks are not just accessories – they are essential for keeping your containers stable and secure. But when should you actually use them, and why are they so important?

When should you use twistlocks?

• When stacking containers
  When containers are placed on top of each other – for example, in ports, on ships, or at construction sites – twistlocks connect their corner castings mechanically. Without them, even small movements can cause shifting or tipping.

• During transport by truck or train
  Vibrations and movements during transport can make containers shift. Twistlocks lock them firmly in place, preventing movement – even during heavy braking or sharp turns.

• For stationary setups in exposed areas
  Even on land, strong winds or uneven ground can pose a risk. Twistlocks add an extra layer of safety when containers are placed in one spot for a longer time.

Why are twistlocks indispensable?

• Safety first
  A shifting container can cause major damage – to goods, equipment, and people. Twistlocks prevent this by creating a strong mechanical connection.

• Stability in all weather conditions
  Whether it’s windy at the port or the ship is rolling in heavy seas, twistlocks keep containers securely in place.

• Quick and easy installation
  Twistlocks require no special tools and can be locked or released in seconds – without compromising strength.

Different types for different needs

At Specialcontainer, you’ll find twistlocks for both temporary setups and permanent installations, including:

Twistlocks are a small investment that can save you from big problems. They create a secure, stable connection between containers via the corner castings – whether during transport, stacking, or stationary use.
