Product Introduction & Application
QU series crane guide rails have various models such as QU70, QU80, QU100, QU120, and the numbers represent the width of the rail surface. The fixed lengths are 9m, 9.5m, 10m, 10.5m, 11m, 11.5m, 12m, and 12.5m.
Commonly used steel grades include U71Mn, U75V, etc. These materials have high strength and toughness and can withstand the huge loads and impact forces during the operation of the crane.
During the rolling process, the size of the rollers, rolling speed, and reduction are precisely controlled to strictly control the dimensional accuracy of the guide rails. This not only helps to improve the wear resistance and corrosion resistance of the guide rails, but also reduces the friction coefficient between the wheels and the guide rails, making the crane run more smoothly.
