| Abstract: | After decades of continuous development,the electrical control system of bridge cranes has undergone several changes and technological striking steps,and,at every stage,with the different practice theories and technological merit,both the circuit structure and the control characteristics come with obvious characteristics of the times.So far,each of the typical control circuits for hoisting mechanism developed for the applications of bridge crane is endowed with different characteristics.From low-accuracy to high-accuracy speed control,from the relays and contactors to the PLC,controlled silicon and inverter,all technologies are subject to continuous development with distinct characteristics of the times. |
