Current collector TC 9A
Current collectors are designed to remove current from the trolleys in order to provide power to the electrical equipment of cranes. The devices are designed to operate from a DC power supply voltage up to 440V and AC power supply frequency of 50 and 60 Hz voltage up to 660V. current Collectors provide operation with a frequency of cycles of reciprocating movements up to 600 per hour at acceleration up to 1 m / S2 and a speed of no more than 150 m / min. The design of current collectors ensures normal operation at: - horizontal oscillations of crane trucks within ± 15 mm and crane bridges ± 20 mm. - vertical fluctuations of crane trucks within ± 15 mm and crane bridges ± 20 mm. current Collectors have climatic versions: U, UHL, T. current Collectors TK are designed for internal wiring. Degree of protection IP00. Natural cooling. Noise level-below the approved sanitary standards CH2.2.4/2 1.8-562-96. Group of operating conditions for mechanical factors-M3.
