The Automatic Load Transportation by Wind Disturbance

Abstract

The idea of the automatic handling of the flexible suspended load by cranes working in different air condition has been presented in the paper. The microprocessor control systems worked out for cranes give the possibility to automatic position the handling load in the every point of the three dimensional transport space with simultaneous elimination of the load oscillations after the starting and braking periods. It has been achieved without the necessity of usage other mechanical damping devices and without the feed back from load oscillations which is the essence of the worked out handling technology. The system has been supplied with compensation of the wind action giving possibility to handling of the loads in different air condition. The problems connected with the wind disturbance acting on the drive and control system and results of the simulation dynamic tests have been described in the paper.
