CNFX does not score or rank suppliers. Buyers must verify all claims and documents with the legal manufacturer before ordering.
It removes finished steel coils from the downcoiler mandrel and transfers them to the next stage, such as a conveyor or packing station, ensuring safe and efficient material flow.
Reference ranges include coil weights of 5-30 metric tons, outer diameters of 800-2000 mm, and widths of 600-1600 mm. Actual capabilities depend on the specific model and must be confirmed with the supplier.
After the mandrel collapses or retracts, ejector arms or plates engage the coil and push it axially off the mandrel onto a transfer car or conveyor. The motion is hydraulically or electromechanically actuated and precisely controlled.
The system references standards such as IEC 60529 for ingress protection, and GB/T 700 for material grade. These are verification references; compliance must be confirmed with the manufacturer.
