Electrical control system of gantry crane

2010 
The utility model discloses an electrical control system of a gantry crane, which comprises an operating part, a control part, a frequency converter, a plurality of power contactors and a plurality of operating mechanism motors, wherein a PLC( programmable logic controller) is adopted by the control part and connected with the operating part, the frequency converter and the power contactors, and the power contactors are respectively connected between the frequency converter and the operating mechanism motors. The PLC is adopted as the control part of the electrical control system, therefore, a plurality of operating mechanisms of the gantry crane can be controlled to act by one set of control system, thus better greatly simplifying the structure of the electrical control system of the gantry crane, and saving a great amount of cost.
