Abstract:

The background of this research is the increasing of marine transportation activities. The following of the activities is the improvement of community welfare nationwide. Accordingly the utilitation of all infrastructures related to sea transportation activities, should be improved in order to make the distribution of goods less expensine. The cost of loading and unloading by using shore crane and ship’s crane are different.

The quay crane scheduling problem plays an essential role in the port container terminal management paradigm, as it is closely related to the berthing time of ships. In this article, we focus on the quay crane scheduling problem based on a special strategy, which forces the quay crane to move in one direction during the process of unloading and loading the containers. The scheduling problem that arises when this strategy is applied is called the one-way scheduling problem of quay cranes in the literature.

Abstract This research presents numerical findings on the seismic response of a tower crane employing anti-seismic joint dampers at its base. The study demonstrates that these damping elements effectively mitigate dynamic actions induced by seismic forces, reducing stress magnitudes by approximately 10%-15% without increasing overall displacement. Moreover, static loading configurations reveal minimal differences in mechanical behavior between cranes with and without damping elements, indicating negligible displacement increases when utilizing damping mechanisms.

The size and weight of modern STS container cranes are increasing to satisfy the demand for bigger ships. This is expected to result in more lateral load when excited by seismic motions. The existing Korean STS container cranes did not behave properly during several recent moderate earthquakes in South Korea. Typical Korean STS container cranes must be checked for the earthquake-resistant capacity. In this research, two nonlinear static an

The efficiency and profitability of the warehouse depends on their efficiency. The traditional design of a rack stacker crane includes a trolley that moves along the rails on the floor of a warehouse, a column mounted vertically on the trolley, along which a carriage with a load gripping device and a load rises. The disadvantages of the traditional crane design are the relatively large mass of the trolley, the need to move it along with the column in a horizontal direct
