PQC EPT control
PQC tower crane EPT control system is an economical EPT control solution based on the advanced foreign technologies.The system integrates slewing, luffing and hoisting mechanisms and power supply into a case.Compared with RCS,PQC EPT control system is more compact in structure and simper & more economical in circuit. This electronic control cabinet slewing mechanism adopts RCV speed regulation with features of stable operation and accurate positioning.Luffing mechanism adopts 2 control modes:3-gear self-coupling voltage reduction + eddy speed regulation or 2-gear pole-changing speed regulation. Hoisting mechanism adopts 3-speed motor pole -changing speed regulation. The traditional circuit is improved, overcoming problems of easy contactor damage and large impact on the mechanism during hoisting or speed reduction of motor. Temperature range:-20ºC-+40ºCHumidity:lower than 85%RH(no moisture condensation)
Altitude:the attitude of installation location shall not be higher than 1000m. Power grid quality:the voltage fluctuation range shall not EPT ±10% of the rated voltage. Power capacity shall be guaranteed fully.
