Efficient Railway Container Transport: Remotely Controlled Twistlocks for Double Stacked Containers


Before we dive into the topic of remotely controlled twistlocks and their use in the railway industry, let's briefly discuss what twistlocks are and their importance in container transport.

Twistlocks are devices that secure containers to different transport modes, such as ships, trucks, and rail cars. They are used to prevent containers from moving during transport and ensure the safe delivery of goods across long distances. Without twistlocks, containers would shift and potentially fall during transport, leading to serious safety hazards and damage to the goods being transported.


In the railway industry, twistlocks are especially important for securing containers on flatcars. One of the challenges in the railway industry is double stacking of containers, which requires the use of twistlocks, also known as a double-stack connector or interbox connector. Interbox connectors (IBC) connect the upper and lower containers, preventing them from moving independently of each other. Locking and unlocking these connectors can be a time-consuming and physically demanding process, especially when done manually. Furthermore, the manual process of securing containers during double stacking can be dangerous for workers, as they must climb onto the flatcars to manually lock and unlock the connectors. Using semi-automatic twistlocks is still not efficient enough and the unlocking process exposes the workers to several occupational hazards.


This is where remotely controlled twistlocks come in. With advancements in technology, remotely controlled twistlocks can be operated from a safe distance, reducing the need for workers to physically climb onto the rail cars or unlock semi-automatics from the side. Using remotely controlled twistlocks not only saves time but also significantly reduces the risk of accidents and injuries to workers.


By integrating remotely controlled twistlocks, real-time monitoring of the container locking status is made possible. This level of monitoring helps ensure the containers remain safely and securely in place during transport, giving the all stakeholders additional peace of mind.

In addition to improving the safety of workers, the use of remotely controlled twistlocks can also make the doublestacking process more efficient. By reducing the time spent in the terminal, the overall efficiency of the railway system can be improved, resulting in faster transport times and potentially lower costs for the operators.


Overall, the use of remotely controlled twistlocks has the potential to significantly improve the efficiency and safety of double stacking in the railway industry. By reducing the time spent in the terminal and improving the safety of workers, remotely controlled twistlocks are poised to be a game-changer in the world of rail transport.
