Product Description

Tower crane Hoist Resistance Box RW4F-225M-4 / 8-3Y / 24 / 24KW. RW4F-250M-4 / 8-4Y / 30 / 30KW. RW4F-250L-4 / 8-5Y / 37 / 37KW. Applicable to AC 50HZ voltage to 500V and DC voltage 440V circuit, mainly as a motor starting, braking and speed control.
Factory dedicated data. Three-stage resistors R1, R2, R3. Up 1 speed, 2 steps: eddy current brake speed. Up 2 files then cut off a resistor. Up 3 files: Cut the vortex. Then delay 2 seconds, remove all two resistors. 4 files cage system. Two - speed motor. 1,2,3 files, 8 very low speed. 4 files, with 4 pole high speed. Low speed to high speed, converter HKJ closed use.
24 / 24KW, 30 / 30KW, 37 / 37KW tower crane dedicated resistance box, from the economic security and other considerations, has its wide range of applications
