Together with the Austrian crane manufacturer Hans Künz GmbH, LASE has successfully implemented a Load Collision Prevention System (LaseLCPS-2D) for two crane systems at the Intermodal Terminal WienCont in Vienna, Austria (view photos in gallery).
One of the biggest container terminals for inland ports in Europe, WienCont handles approximately 200,000 containers annually.
WienCont put a high emphasis on the Soft Landing function for the crane driver assistance system. This function is activated while hoisting the load, and ensures that the container drops without any wear, and also reduces noise. The Intermodal Terminals are mostly situated in residential areas, so low noise pollution helps the company remain neighborly.
The measurement system consists of two 2D laser scanners from the LASE 2000D-Series, which provide precise 2D profiles to the measurement software. The laser scanners are mounted under the crane trolley in order to generate a scan area in both trolley directions.
While driving over the container stacks a current height profile is created. The laser scanners simultaneously measure the height of the load (spreader with or without container).
If a finished container moves, the relative distance between the objects is known by the relative position measurement. Thus, the measurement system can control the hoist, and the object can be dropped softly.
The measurement system can also prevent collisions if the hoist (with or without container) drives over the container stacking area.
LaseLCPS is also available as a 3D version (by the use of 3D laser scanners) and ensures a safe and gentle handling of materials for RMG-, RTG- and STS-Cranes in the biggest container ports worldwide.
