|The requirement of ever faster and optimized 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. Symeo applies its positioning sensors on reach stackers, straddle carriers, empty handlers, terminal tractors, automatic stacking cranes, RMGs and RTGs as well as large ship-to-shore cranes.
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 and other relevant data transfer to a centralised terminal operating system (TOS) can be through Symeo´s own 5.8 Ghz radio interface, or using existing 802.11 wifi and GSM infrastructure. Even a narrowband radio interface is available.
LPR-2D position sensors for container handling equipment (CHE)
LPR transponders mounted to the light poles of the terminal serve as reference marks. The typical range is about 400 m. An LPR-2D receiver on the CHE determines its position as well as orientation and speed in real-time. Vehicle data like for example load-change signals, driver ID and hoisting height are acquired by a connected IO box. Event triggerd pon picking up or unloading a container or at predetermined invalls, position and vehicle data 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 partially affected or shielded by vessels, buildings or cranes, the combination of satellite positioning and LPR-2D is the most cost efficient solution to seamlessly and reliably track crane and vehicle movement.
Intermodal terminals as well as large sea terminals 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.
