The German BG (Employers’ Liability Insurance Association) has certified Lase’s load collision prevention system as Performance Level D – Category 3, meaning it exceeds today’s requirements on safety standards in the port industry.
The performance levels EN ISO 13849-1 are parameters for the reliability of how a control system complies with safety functions.
According to a statement from the laser systems-manufacturer, the ceritification confirms the product’s “high development status and also acceptance on the market”.
The product LaseLCPS-3D-2D is a combined 3D/2D measurement system consisting of 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 3D profile scan in gantry and trolley direction is processed before the first move.
The scan planes of the 2D- and 3D laser scanner are projected orthogonally to each other.
The laser scanners also scan over the yard during the movement in order to measure into shadow areas, which have been covered by higher stacks in front before.
Within this collision prevention check, a surveillance cube around the load proves an overlap with the container profiles in the yard according to the manufacturer.
In the event of an overlap, the system slows down the crane travel and then finally stops the container move.
The system also has a soft-landing function for gentle container handling that leads to less spreader wear and a reduction of the operation noise, noted the Lase statement.
