Horizontal Force on Tire Gantry Crane

Applied Mechanics and Materials, 2013
Difference of trolley traction distribution and slip angle of tire wheels may cause extra horizontal force to legs of tire gantry crane. The case and cause were studied to estimate the force for the crane design, control, and operation. And that was compared with one specialized in the design rules of rail gantry crane.

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.

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

Passive teleoperation of a gantry crane

2007 European Control Conference (ECC), 2007
This paper presents the design of the teleoperation system for a gantry crane, entirely using tools from passivity theory. Gantry cranes still pose a control challenge, mainly due to the problem of load swing suppression, in underactuated conditions.

Nonlinear Control of a Gantry Crane

2013
This paper treats the nonlinear control of a laboratory model of a gantry crane, where a trolley can be moved on a rail and the load is fixed at the end of a rope of variable length. The system is differentially flat, and the coordinates of the load, which also are the variables to be controlled, are a flat output.

Control Methods for Gantry Crane

IFAC Proceedings Volumes, 2000
Abstract The paper presents theory and experiments carried out on the scale physical model of a gantry crane supporting theoretical lectures on Model Predictive Control (MPC). The optimal control for scale physical model of a gantry crane providing antisway control task can be computed using efficient methods which satisfy specified boundary ...

Ultracapacitor storage for a 50t capacity gantry crane

2012 XXth International Conference on Electrical Machines, 2012
This 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.

Intelligent control of overhead gantry cranes

2009 6th International Symposium on Mechatronics and its Applications, 2009
Overhead 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, 2014
We 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.
