The three-dimensional solution of the application LaseLCPS-3D – Load Collision Prevention System is a measurement system which works with two 3D laser scanners which are mounted under the trolley.
The specific LaseLCPS software application collects the scan data, does all needed calculations and sends the results to the machine PLC.
In order to measure all relevant stacks a 3D profile scan in trolley direction will be processed before the first move. 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
