Load swing reduction in manually operated bridge cranes

2017 IEEE 3rd International Forum on Research and Technologies for Society and Industry (RTSI), 2017
In this paper, a procedure for control system design of an anti-sway system for manually operated bridge cranes is presented. Specifically, the human operator acts by means of a push-button panel to operate the crane and thus is considered as a disturbance to the closed loop control system that regulates to zero the angle of the load cable with respect

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

Hart Crane's Bridge to Cathay

American Literature, 1944
THROUGH the waste land of the hollow men Hart Crane groped blindly for a passage to India. If, confused by the currents and crosscurrents of scientific materialism, mystagoguery, and philosophic idealism, he found only the West Indies, he was not unaware of his failure.

Stability Analysis of Bridge Crane Hoists

Applied Mechanics and Materials, 2014
Hoist bridge crane swinging phenomenon often occurs during the operation, making the work more difficult, there is a certain danger. To solve this problem, anti-sway system for overhead cranes depth study to identify the main factors affecting heavy lifting swinging; proposed single neuron PID control strategy, while using MATLAB simulation used to ...

Intelligent anti-swing control for bridge crane

Journal of Central South University, 2012
A new intelligent anti-swing control scheme, which combined fuzzy neural network (FNN) and sliding mode control (SMC) with particle swarm optimization (PSO), was presented for bridge crane. The outputs of three fuzzy neural networks were used to approach the uncertainties of the positioning subsystem, lifting-rope subsystem and anti-swing subsystem ...
