The system adopts SKK jet oil twin screw air compressor head, and the system adopts 0-100% air displacement. When the amount of air is decreased, the discharge volume decreases, and the electric current of the motor decreases as well. When the air is not used, the empty compressor runs, and the empty car stops automatically. When air volume increases, recovery of heavy car. Energy efficiency is optimal. Supernormal cooling system design, especially suitable for high temperature and high humidity in Asia. Excellent isolation technology and noise reduction measures, as long as the minimum ventilation and maintenance space, can be installed your compressor.

PQC tower crane electrical control system is an economical electrical 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 electrical 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 exceed ±10% of the rated voltage. Power capacity shall be guaranteed fully.
