RESEARCH ON IMPROVED THE MULTI-OVERHEAD CRANE CONTROLLER BY USING PLC
This paper presents researchs and designs to improve controller of multi-overhead crane system in a car assembly factory by using PLC. The abilitys of the new controller are automatic moving and lifting, it also has ability of automatic stopping to avoid suddenly collisions. The controller ensure to improve productivity and minimize of collisions that make to damage goods and equipment during handling. Tests at the factory showed that the improved system allowed an increase of 10-15% and there was no collision between cranes during loading. The overall evaluation of the results shows that the system works well, meeting all technical requirements.
