This specific version of the application LaseLCPS-3D-2D – Load Collision Prevention is a combined 3D/2D measurement system consisiting of each one 2D and one 3D laser scanner mounted under the trolley.
The LaseLCPS application software collects the scan data, does all needed calculations and sends the results to the machine PLC. In order to measure all relevant stacks a 2D profile scan in gantry as well as trolley direction will be processed before the first move.
Two different scan planes are projected orthogonally to each other. An additional 3D scan will be done after the trolley has passed the highest point of the stack in order to detect shadow areas. A further collision prevention check by the dynamic surveillance cube has the function to avoid collisions between the empty spreader or container on the spreader and containers in the stacking area. The position (cube center) is located in the middle of the spreader‘s lower edge. The expansion of the cube is depending on the adjusted length of the spreader (20’, 40’, 45’), height of container on the spreader, moving direction and the velocity of trolley and hoist.
This intelligent and innovative solution is built to diminish the risk of collisions and accidents in container stacking areas. The measurement system by LASE is applicable for topography detection and collision prevention at RTGs and RMGs cranes.
Common system features:
Stack height information for path optimisation
Avoids collisions between load and stack
Applicable for RMGs and RTGs
Avoids collisions with adjacent stacks in gantry direction
Gentle container handling trough soft landings & less spreader wear
Both 2D and 3D profile scan in gantry/trolley drive direction
