Product Introduction & Application
Common models of crane rails include QU70, QU80, QU100, QU120, etc. The number after QU indicates the width of the rail head.
QU70: Rail height 120mm, bottom width 120mm, head width 70mm, waist thickness 28mm, theoretical weight 52.8kg/m.
QU80: Rail height 130mm, bottom width 130mm, head width 80mm, waist thickness 32mm, theoretical weight 63.69kg/m.
QU100: Rail height 150mm, bottom width 150mm, head width 100mm, waist thickness 38mm, theoretical weight 88.96kg/m.
QU120: Rail height 170mm, bottom width 170mm, head width 120mm, waist thickness 44mm, theoretical weight 118.1kg/m.
Crane rails are usually rolled from steel with high carbon and manganese content, and the typical material is U71Mn steel. This steel has high strength and wear resistance, and can withstand the huge pressure and impact force during the operation of the crane. At the same time, it has good toughness to prevent the rail from breaking during use.
38kg/m heavy rail: Rail height 134mm, bottom width 114mm, head width 68mm, waist thickness 13mm, theoretical weight 38.733kg/m.
43kg/m heavy rail: Rail height 140mm, bottom width 114mm, head width 70mm, waist thickness 14.5mm, theoretical weight 44.56kg/m.
50kg/m heavy rail: rail height 152mm, bottom width 132mm, head width 70mm, waist thickness 15.5mm, theoretical weight 51.46kg/m.
60kg/m heavy rail: rail height 176mm, bottom width 150mm, head width 73mm, waist thickness 20mm, theoretical weight 60.76kg/m.
75kg/m heavy rail: rail height 192mm, bottom width 150mm, head width 75mm, waist thickness 25mm, theoretical weight 74.6kg/m.
The steel types of railway heavy rails are mainly medium carbon steel or medium carbon alloy steel, such as U71Mn. There are strict requirements for the content of each element in the steel, such as the carbon content is generally 0.65% - 0.77%, the manganese content is 1.10% - 1.50%, etc. The strength, toughness and wear resistance of the rails are guaranteed through reasonable chemical composition design.

Product Packaging & Delivery
When transporting rails, we use the following transportation methods:
Steel strapping: Heavy rails are usually bundled in a certain number (such as 5-10) using high-strength steel strapping. Ensure that the heavy rails will not loosen during transportation.
Steel wire bundling: For some heavy rails with higher requirements or special specifications, steel wire bundling is also used.
Protective packaging
End protection: The two ends of the heavy rails are easily hit and worn during transportation, so special end protectors are used for protection.
Overall protection: In order to prevent the surface of the heavy rails from rusting and corrosion, a layer of anti-rust oil or anti-rust paint will be applied to its surface.
