Motion control of a gantry crane with a container

AIP Conference Proceedings, 2018
The transportation of a container by a gantry crane in a given time from one point of space to another is considered. The system is at rest at the end of the motion. A maximum admissible speed is taken into account. The control force is found using either the Pontryagin maximum principle or the generalized Gauss principle.

Flatness based Control of a Gantry Crane

IFAC Proceedings Volumes, 2013
Abstract This contribution deals with flatness based control of a laboratory model of a gantry crane. The mechanical model has 3DOFs, where a trolley can be moved on a rail, the load is fixed at the end of a rope and can be lifted or lowered by coiling or uncoiling this rope on a cylinder.

Intelligent Control of industrial gantry crane model "3D Crane"

International Journal of Emerging Trends in Engineering Research, 2022
3D Crane represent Laboratory model of industrial gantry cranes which are widely used in industry. In this work, a dynamic model of 3D Crane is presented and tow artificial intelligence techniques were synthetized and applied to the model : Fuzzy Logic Control (FLC) and Adaptive Neural Fuzzy Inference System (ANFIS); the purpose of the control is the ...

Implementation of wireless control on electrical bridge cranes and gantry crane

2015 23rd Telecommunications Forum Telfor (TELFOR), 2015
The paper presents practical experiences during implementation of radio remote control to the electrical bridge cranes in machine room HEP "Perucica" and gantry crane at a lock on Tisa. In addition to the new way of control, also kept the old way of control from cabine cranes as provided with selector switch. Installation of radio remote control system

Seismic Response of Gantry Cranes

2020
Gantry cranes are customized to meet specific requirements at a facility. Due to their unique configuration, prescriptive design, based on empirical rules, cannot be justified. Gantry cranes have some brittle elements (joints and connections) and some ductile elements (steel beams and columns).

Regulation strategy of an Ultracapacitor storage model for a gantry crane

IECON 2013 - 39th Annual Conference of the IEEE Industrial Electronics Society, 2013
This 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

Gantry cranes

2003
Portal crane (1) for loading and/or unloading a ship having a multiplicity of bays for containers (10) comprising a gantry (2) with travelling gear (5) for supporting the gantry on a quay (13), a boom supported by the gantry made up of a horizontal beam (6) and a jib (7) that during loading and/or unloading is an extension of the beam, and at least one

Travelling gantry crane with suspended mass

2000
Here we must achieve a model, in order to regulate both the freedom degrees of a travelling gantry crane composed of a mass truck M, moving according to the x axis under the action of an F force and m mass suspended from a 1 long cable. The m mass oscillates from its cable with a θ angle in relation to the vertical attached point.

Lumped Mass Models of Gantry Cranes

2019
This chapter discusses the mathematical modeling of gantry crane systems, considering the subsystems of a crane to be rigid bodies. Such a formulation does not reflect the deflections within the individual parts of the crane but only considers their rigid body movements and results in a lumped mass model (LMM).

Fatigue Analysis of Gantry Crane Based on ANN

Advanced Materials Research, 2012
Fatigue failure is the major cause of malignant accident of gantry crane. In this paper fatigue analysis of gantry crane is studied . Based on the result of FEM(Finite Element Method) and the ANN(Artificial Neural Network), nonlinear ralationship between fatigue damage and dynamic load is built.
