· 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. Automatic Grabbing System of Spreader · Image recognition and positioning of truck under crane and out of crane · Ship tilting detecting control technology · Container lock hole image recognition and positioning · Ship slot recognition and positioning Intelligent Control Technology of Spreader Track · 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-sway and Anti-torsion Control Technology · 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. Multi-function Slewing and Anti-snag · 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 damage to the crane or the ship's hold.
