RTG-RMG solutions

Camco offers three product groups for RTG/RMG yard automation.

Truck identification & handover automation

The first and most critical product group focuses on the reliable identification of external and internal trucks at RTG/RMG cranes during container handover. This process is essential when transferring containers between chassis and stacks, or vice versa. For internal trucks, the handover can be fully automated, called auto job stepping.

Container ID capture

The second application captures the container ID during crane moves, typically for RMG cranes. Images are taken of both the door and rear sides to ensure accurate identification. As alternative our spreader camera can be used. It reads the roof container number and can check for roof damage.

RTLS-based move verification

The third product group is based on RTLS technology. RTG/RMG cranes and internal trucks are equipped with Camco’s GNSS receivers and PLC controllers. Data is retrieved directly from the RTG/RMG PLC. Crane and spreader position data is used to validate handovers and stack moves. All data is processed by CHEOPS (RTLS server) and TWINBRIDGE (Digital Twin), enabling a real-time 3D view of the terminal.

Accurate container and truck identification for every approach

Camco’s RTG/RMG solutions provide consistent, high-accuracy truck identification, regardless of how the truck positions itself. The result: fewer manual checks, fewer exceptions, and a smoother handover between a truck chassis and crane operations.

Handover: many solutions

Identification of internal and external trucks at RTG/RMG cranes is inherently complex and there is no single, universal solution. Similar to gate operations—where a combination of RFID and license plate recognition delivers the best results—we recommend a hybrid approach for truck identification at the crane interface.

For RMG operations, identification can typically be performed while the truck is stationary, as the crane size allows for reliable static identification.

For RTG operations, the situation is more dynamic. Identification must take place while either the RTG moves toward a waiting truck or the truck approaches a waiting RTG. Once a truck is positioned under an RTG and stationary, reliable identification becomes difficult. In these cases, only RFID door tags or roof numbers provide the most effective solution.

For both RTG and RMG environments, the preferred location for RFID tags is on the truck doors. Windshield-mounted RFID toll tags are less suitable due to their forward-facing position.

As an alternative, truck roof numbers can be used. While this works well for internal trucks, large-scale deployment for external trucks remains challenging.

RMG Camera

With a percect digitalised handover process at the RMG the need of reading the container number is not so high. Nevertheless we offer this solution mainly for RMG’s. 2 cameras are installed on the legs of the RMG, during the move from chassis to the stack, or vice versa, when the container passes the legs, the container door or rear is captured.

RTLS, the keystone of a digital twin

Camco digital twin solution called THE TWINBRIDGE needs real time data of every yard equipment on a terminal including RMG’s and RTG’s. Those cranes are equiped with Camco’s GNSS solution and a Camco PLC controller to read the equipment PLC. Besides reading the spreader position and status, other telematic data is collected and send to CHEOPS, Camco’s RTLS backend server.

Part of THE BRIDGE

All handover events at the RTG/RMG are supported by THE BRIDGE giving

  • Real-time visibility
  • Easy exception handling
  • Clear traceability of every crane-truck interaction
