The Optimization Of The Flexibly SuspendedLoads Transport By Microprocessor ControlledOverhead Cranes

The optimization of the transport of the flexible suspended load for overhead cranes has been worked out. The solution of the problems connected with oscillation of the flexibly suspended load, positioning of the load, limitation of the bevel angle of the bridge, and friction of the wheel flanges and power regulation are presented in this paper. The problems have been solved by means of a microprocessor automatic and semiautomatic continual control of the speed of the travelling and traversing mechanisms, and constant power regulation for hoisting and lowering of the load. The system can be applied to the transport of the load in the transport area where the fixed obstacles are situated.
