Shore-to-shore container cranes

Through the laser positioning system installed on the main girder of the quay crane, the fast and accurate alignment of container trucks is realized, which is suitable for the needs of automatic operation of the terminal and effectively improves the efficiency of container loading and unloading.
Through the encoder position detection and the dynamic memory storage technology of the spreader running track, the safety path is automatically calculated, which greatly improves the operation efficiency.
By detecting the relative angle deviation between the spreader and the trolley, the running speed of the trolley is controlled, so that the spreader quickly stops swinging.
The tilting cylinder or motor is controlled by the angle detected by the anti-sway system, and then the tilt angle of the spreader is controlled to achieve anti-torsion.
The power factor reaches more than 0.9, the harmonic amount is greatly reduced, and the energy-saving effect is obvious.
The advanced active inverter technology can convert the kinetic energy and potential energy stored in the machinery into electrical energy, which can be efficiently fed back to the power grid.
