To supply power to electrical equipment, the crane is equipped with a flexible supply cable wound on a drum, or a trolley current supply system. To implement the turning of containers, the cranes are equipped with a swing beam or a swing trolley. In container loaders, high speed of container handling is ensured by the ⌊⌋ -shaped design with a lower crossbar, which allows transporting 20-45-foot containers between the crane legs without turning over the entire lifting height, as well as the spatial suspension of the spreader, which dampens vibrations. |
