Features
ALEX EQUIPMENT COMPANY
Soft Intelligent Container Positioning Technology
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.
Anti-collision Safety System
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
Power Factor More Than 0.9
The amount of harmonics has greatly decreased, and energy saving effect is obvious.
Energy Recycling Technology
Active inverter technology is applied to transfer the stored dynamic power and potential power into electricity which is recycled to the grid. Moreover, it can resist the pollution to the grid from higher harmonic voltage, thus increasing the power factor of the equipment.
Intelligent Low Voltage Capacitor Compensation
Fully automatic resonance eliminating reactive power compensation device is configured to achieve the average power factor above 0.9, which improves electricity efficiency and reduces wire consumption.
