Against the backdrop of global economic and trade integration, container shipping volumes have surged significantly, driving the trend toward larger container vessels and terminals. This has accelerated the pace of upgrading terminal handling equipment. As the primary handling equipment at container terminals, the operational capacity of ship to shore cranes […]

Background Introduction The world’s first automated container terminal commenced operations in the Netherlands in 1993, ushering in the era of automated container terminal construction. However, prior to 2013, automated terminal development was primarily concentrated in regions such as Europe and North America. It wasn’t until 2014 that Xiamen Yuhai Terminal

The operational efficiency of a container STS crane is largely determined by the performance of each of its components. Key mechanisms include the gantry mechanism, the trolley mechanism, and the hoisting mechanism. As a vital component, the trolley mechanism primarily supports the wire rope to prevent excessive sway during lifting operations.

Wire ropes are extensively utilized in the hoisting, luffing, and trolley traction mechanisms of container STS cranes. As the primary flexible component in container STS crane operations, they offer advantages such as high load-bearing capacity, excellent flexibility, smooth transmission, impact resistance, noise-free operation during high-speed movement, and reliable safety. With advancements

Introduction Container crane hook engagement (hereinafter referred to as hook engagement) collectively refers to situations during container handling operations where, due to various reasons, the crane hook becomes hooked or interferes with fixed structures (such as container guide rails in the ship’s hold or containers fixed to the ship) during
