摘要: In this paper controlled electrical drives for Rail Mounted Wide Span Gantry Cranes are analyzed. The modern solution considers the application of frequency converters all drives. Special attention is payed to multi-motor horizontal movement in sense load distribution. Although it can be considered that motors rigid coupled by mechanical construction, they do not need an equal torque. Presented algorithm provides sharing proportional rated motor power on simple and practically applicable method basis estimated torques converters, controller realized PLC. For wide span gantry efficient skew elimination presented simultaneous between done. algorithms experimentally verified several places industry characteristic results shown paper.
