Ultracapacitor storage for a 50t capacity gantry crane
2012 XXth International Conference on Electrical Machines, 2012This paper presents, for a system consisting of a gantry crane, the sizing of an Ultracapacitor (UC) based storage sytem, and its performance test using a simulated model of the system considered as a multi-axis drive. Preliminary examination of different operating processes has been done.

Gantry crane control: A simulation case study
2013 2nd Experiment@ International Conference (exp.at'13), 2013A simulation teaching experiment to control a gantry crane system is proposed. The control is performed both in open-loop and closed-loop. The open-loop control is based on the Posicast feedforward technique and the closed-loop control uses a two-degrees of freedom configuration.

Intelligent control of overhead gantry cranes
2009 6th International Symposium on Mechatronics and its Applications, 2009Overhead gantry crane systems have been integral part of many heavy industrial applications needing material handling and transportation. This can easily be seen in emerging countries growing rapidly. Single force control input applied to crane moves it to a desired position but also triggers undesired swing on the payload which makes it an interesting

Control of a gantry crane: A reach control approach
53rd IEEE Conference on Decision and Control, 2014We investigate synthesis of piecewise affine feedback controllers to achieve an aggressive maneuver for a gantry crane operating in a cluttered environment. The methodology is based on formulating the problem as a reach control problem on a polytopic state space.

Image-Based Automatic Crack Detection Method of Gantry Crane Track
2022 International Conference on Computer Engineering and Artificial Intelligence (ICCEAI), 2022Aiming at the technical problems of intelligent identification of cracks on gantry crane track, a target detection method was proposed based on machine vision and deep neural network. YOLOv5s is used as the surface defect detection model, and the trained

Fatigue Life Evaluation of Rubber Tyred Gantry Crane based on Minner Criterion
International Conference on Control and Intelligent Robotics, 2022An old rubber tyred gantry crane in a wharf needs safety assessment because of its long service life and high service frequency. In this paper, through the finite element simulation of the crane metal structure, combined with the field stress test, the ...

Journal of Dynamic Systems, Measurement, and Control, 2003
Rest to rest movement of a crane’s swinging load, at the bottom end of a cable, by moving a speed-limited gantry trolley at the top, involves resolving the apparently conflicting demands of exact load positioning and active swing damping. If system parameters are unknown beforehand, best existing strategies offer only asymptotic solutions. The proposed

Regulation strategy of an Ultracapacitor storage model for a gantry crane
IECON 2013 - 39th Annual Conference of the IEEE Industrial Electronics Society, 2013This paper presents, for a system consisting of a gantry crane, the regulation strategy of an Ultracapacitor (UC) based storage system, and its performance test using a simulated model of the system A model for the study of the accumulation of electrical energy in Ultracapacitors was presented. This model was validated by comparing the simulation model

Online Antiswing Trajectory Planning for a Practical Rubber Tire Container Gantry Crane
IEEE transactions on industrial electronics (1982. Print), 2021Rubber tire container gantry cranes (RTG) are the most commonly used equipments to stack containers in ports. With four sets of ropes hoisting the cargo, the system dynamics become much more complicated and unpredictable when compared with traditional ...
