Dynamic Modeling and Validation of Dual-Cable Double-Pendulum Systems for Gantry Cranes

Machines
This paper presents a novel dynamic modeling framework for gantry crane systems based on the cart double pendulum with dual cables (CDPD) model. The CDPD model systematically incorporates the effects of dual suspension cables, equalizer beams, and closed-

Crane Rail Health Monitoring With Laser Vibrometry

Structural Control and Health Monitoring, Volume 2025, Issue 1, 2025.
This paper proposes a method for the evaluation of the combined system of heavy port cranes and the rails on which they run and demonstrates its success. Using techniques from railroad track health monitoring, we record the guided waves created in the rails from the movement of the wheels using laser‐based vibrometry.

Optimizing multiple equipment scheduling for U‐shaped automated container terminals considering loading and unloading operations

Computer-Aided Civil and Infrastructure Engineering, Volume 39, Issue 20, Page 3103-3124, 15 October 2024.
Abstract U‐shaped automated container terminals (ACTs) represent a strategic design in port infrastructure that facilitates simultaneous loading and unloading operations. This paper addresses the challenges of scheduling multiple types of equipment, such as dual trolley quay cranes (DTQCs), automated guided vehicles (AGVs), double cantilever rail ...
