Crane Rail's Model:QU70 rail,QU80 rail,QU100 rail,QU120 rail, QU70 Rail is use for for crane and trolley track. Compared with the railway's heavy rail, crane rail height is low and head width thick waist size is bigger.Crane rail is on heavy rail in our country for the quality inspection is only required to chemical composition and tensile strength. Due to the production batch, the specific model is different, the above of pictures are for reference only, for further details you can contact our sales staff to carry out the specific verification .
