A container crane is a large piece of equipment used at ports and shipping yards to load and unload shipping containers from cargo ships. These cranes are designed to handle heavy loads and can reach high above the ship's deck to lift containers safely and efficiently. They play a crucial role in the logistics and transportation industry, ensuring that goods are moved quickly and effectively. Typically, container cranes are mounted on rails, allowing them to move along the dock. They are equipped with a spreader, which is a device that secures the container during lifting. The use of container cranes has significantly increased the speed of cargo handling, contributing to the growth of global trade and the efficiency of shipping operations.
