The challenge

In traditional container transport operations, drivers must repeatedly exit and re-enter their cabs to manually connect and disconnect trailers. This includes handling air and energy lines, adjusting support legs, and operating twist locks - often in adverse weather conditions. These repetitive tasks not only slow down operations but also expose drivers to significant safety risks, particularly slips and falls during winter.

The innovation

AUCOS-Systems-GmbH has developed a fully automated coupling and uncoupling system that allows drivers to remain safely inside the cab throughout the entire process. The system is made up of three integrated components:

• AUCOS-Coup: Automatically connects the trailer to the tractor unit, supplying air for brakes, power for lighting, and enabling data exchange.
• AUCOS-Lock: Remotely controls the opening and closing of twist locks in any configuration, eliminating the need for manual intervention.
• AUCOS-Leg: Enables the raising and lowering of support legs via the cab, using the data connection established by AUCOS-Coup.

Together, these components streamline the coupling process, enhance safety, and reduce wear and tear on equipment.

How it works

The AUCOS system integrates directly with the truck’s onboard controls. Once the trailer is aligned, the driver can initiate the coupling sequence from the cab. AUCOS-Coup handles the physical connections, AUCOS-Lock secures the container, and AUCOS-Leg adjusts the trailer’s support legs—all without the driver stepping outside. The system uses a combination of hydraulic and electronic controls to ensure precision and reliability.

Case study

Since its first deployment in 2016 at Long Beach Container Terminal (LBCT), the AUCOS system has been installed on over 100 trailers and 50 tractor units. It has since expanded to Vancouver and Hamburg, with the latest full-system prototype showcased in 2024 at the IAA in Hannover.

At LBCT alone, the system has supported over 270,000 couplings, contributing to the terminal receiving the Pacific Maritime Association’s ‘Overall Terminal Safety Award’ in both 2017 and 2018. Operators report high system availability and a significant reduction in accidents and equipment damage.

Potential impact

As the logistics industry moves toward greater automation and safety, AUCOS offers a critical step forward. While current European use is limited to closed terminals due to certification requirements, the system is already road-ready in other regions. Its ability to reduce manual labour, prevent injuries, and streamline operations makes it a valuable asset for any transport or logistics provider - especially as autonomous vehicle technologies become more prevalent.
