Development of Miniature Model of Container Crane for Remote Operation and Automation

Although container cranes are essential to port logistics, issues remain regarding operational efficiency and safety. These issues are caused by factors such as aging operators, labor shortages, and sway caused by strong winds, acceleration, and deceleration. In particular, in the development and evaluation of remote operation and automation systems for container cranes involves high costs and strict safety restrictions, which reduces development efficiency. Therefore, this study designed and manufactured a small-scale crane model at approximately one-thirtieth the actual size and evaluated its operation. As initial steps toward remote operation and automation, remote control and automation control systems were constructed using the small-scale crane. The feasibility of basic operations was confirmed. Furthermore, the position of the spreader was estimated using LiDAR, and its effectiveness was verified.
