· A laser positioning system is installed on the girder to position the truck precisely and fast. This can be applied in the automatic terminal operation and improves the handling efficiency.
· Image recognition and positioning of truck under crane
· Image recognition and positioning of truck out of crane
· Ship tilting detecting control technology
· Container lock hole image recognition and positioning
· Ship slot recognition and positioning
· Optimized 'and safe route of spreader is calculated based on the encoder position detection and spreader track storage. Handling efficiency can be improved greatly
· Electrical anti- torsion: Anti-sway system detects angle to control trim/list cylinder or motor, thus controlling the spreader trim/list and realize anti-torsion.
· Advanced hydraulic control technology is applied to cut off the power of control system when there is a snag during the hoisting. The hydraulic valve will be open and the oil cylinder will unload immediately to avoid destroying to the crane or the ship's hold.
· Anti-collision between gantry and truck
· Anti-collision between two gantries
· Anti-collision between gantry and the transfer platform
· Anti-collision between gantry rail and objects beside
· Anti-collision between trolley and mast trolley
· Anti-collision between boom and the mast or buildings
· The amount of harmonics has greatly decreased, and energy saving effect is obvious.
· Active inverier echnalogy is applied to transfer the stojed dynamic power and potential power into electricity and be recycled to the grid. At the same time, it can resist the pollution to grid from higher harmonic voltage, thus increasing the power factor of the equipment.
· Full automatic resonance eliminating reactive power compensation device is contigured to achieve the average power factor above 0.9 or more, which improves electricity efficiency and reduces wire consumption.
