The application LaseSPC – Straddle (Carrier) Positioning Crane is a 2D measurement system consisiting of two 2D laser scanners mounted each at the water- and the landsided gantry.
The straddle carriers are equipped with reference markers on all four legs and after the straddle carrier is under or approaching the crane, the measurement system detects them and calculates the exact position of the straddle carrier (SC).
With the use of LED displays, the straddle carrier driver receives a feedback about his relative position to the crane centre and the final target position. Possible corrections of the position will be shown as numeric displacement information in order to move forwards or backwards.
Furthermore, the information of the straddle carrier will be hosted to the crane control system in order to prevent the hoist lowering into the lane where the straddle carrier is. The system offers an exact positioning of straddle carriers and is even applicable for multi-lane operations, whereby two straddle carriers can measure at the same time.
