Gordon crane technician started TH crane trouble shooting this morning. The problem is found that there is no 115VAC power supply to energize a
main coil which is used to switch on 450V AC power supply to crane. He did a test and found the crane could be operated by big yellow pedant
in control room when he manually gave the coil 115VAC power supply to energize it.. At that moment, the crane is set to big yellow pedant operating mode. |
