More Information
Summary:The utility model provides a portal frame and a forklift, the portal frame comprises an outer portal frame, an inner portal frame, at least two linear lifting driving mechanisms, a stay wire encoder and a signal processing mechanism, a fixed part of the stay wire encoder is suitable for being fixedly connected to a fixed end, and a stay rope of the stay wire encoder is connected with the inner portal frame. According to the portal frame with the structure, when the inner portal frame is lifted to the top, the inner portal frame drives the stay wires to be lifted, all the stay wire encoders record electric signals of displacement after the inner portal frame is lifted to the top, the stay wire encoders transmit the electric signals of the lifting displacement to the signal processing mechanism, and the electric signals of the lifting displacement are processed and converted into lifting displacement through the signal processing mechanism; the height value, needing to be adjusted, of each linear lifting drivin
