Ship-to-Shore Cranes: Everything You Need to Know
Port cranes play a vital role in day-to-day port operations. Without the help of these cranes, containers can’t be stacked in the yard or loaded on the vessel. There are two main types of port cranes: quay cranes and yard cranes. Quay cranes, also known as ship-to-shore (STS) cranes, operate directly from the ship to the shore and vice versa, while yard cranes handle containers within the port’s yard.
Overview of Ship-to-Shore Cranes
Ship-to-shore cranes are essential for loading and unloading containers from large vessels. These cranes are designed to handle heavy loads efficiently, ensuring quick turnaround times for container ships. They are typically positioned along the quayside, where they can easily access vessels docked at the port. Major manufacturers, including Konecranes, Liebherr, and Paceco, offer a range of STS cranes tailored to various operational needs.
