Tracking of Transport Vehicles and Cranes on Container Terminals

Strong growth in container turnover worldwide shapes the terminals of the future. On the given space of the terminals, logistics must ensure the efficient storage and retrieval of containers in a minimum of time.

Exact positioning and tracking of all containers is therefore key. Continuous tracking of the carrier position has proven to be the most effective solution for that requirement.

LPR-1D distance sensors for container cranes

Both for existing and new cranes, LPR sensors offer a unique way of acquiring the absolute position of the cranes and the respective crane trolleys or to avoid collisions between the cranes. Position data transfer to a centralised terminal management system can be through Symeo´s own radio interface, eliminating the need for wireless LAN access.

LPR-2D position sensors for straddle carriers and reach stackers

LPR transponders mounted to the light poles of the terminal serve as reference marks. The typical range is about 400 m. A base station on carriers and cranes determines its position as well as orientation and speed in real-time. Upon picking up or unloading a container this position is sent to the inventory management system to keep it updated for an optimised operation.

Vehicle positions are available in real time in order to assign jobs to the best positioned transporter. Early collision warnings are available as a by-product. The destination of a transport can be fuzzy until the vehicle comes close to its final destination and receives its precise unloading position, e.g. a certain lane under a crane bridge.

Handover positions under the ship-to-shore cranes can be precisely teached by the driver of the straddle carrier.

Combined LPR & D-GPS Receiver

If GPS satellite reception is only partially affected or shielded by vessels or buildings, the combination of satellite positioning and LPR-2D is the most cost efficient solution to seamlessly track crane and vehicle movement.

Intermodal terminals do especially benefit from these advantages.

With seamless tracking of container movements, terminal logistics can rise to future challenges.

Symeo´s maintenance-free tracking technology is fully independent from weather and other conditions and is not subject to wear & tear or recalibration. Devices are marine grade quality.
