Twist and Lock: How Important are Twistlocks for Shipping Containers?

Cargos around the globe, whether docked in ports or in transit, require exceptional care and attention. This is because their safety and security are, admittedly, necessary evils in this industry.

For this reason, it is imperative that cargo containers should have twist-locks.

Twistlocks are devices that are primarily incorporated to join and lock containers vertically and/or horizontally. As a result, these connection gizmos became very vital to safely securing containers for transportation and retrofitting purposes.

Additionally, twist-locks were standardly designed to secure containers while on marine, rail, or land transport. They make certain that containers stacked on top of each other are secured to anchor points. Thus, twistlocks prevent accidental dislodging.

How does twist-lock work?Dovetail Twistlock foundations (45- degree)

  • First, insert a cone-shaped top into the top or bottom of a corner casting.
  • Lastly, rotate the lever to 90 degrees to lock it into the corner casting.
    • Once locked in place, it can no longer be separated for the corner casting.
    • Some have built-in levers or mechanisms, others may require tools to lock them in place.

Whatever your container safety needs may be,  we have a twist-lock available for you.
