Material for rail of crane is of strong strength because of high carbon content, but of poor weldability, which makes more cracks. Strict technique is required in such welding.
The Speedy Rail beam is a heat-treated aluminium alloy profile with hollow cross-sections that give it high strength under torsion and deflection stresses.
快速铁路是束热处理铝合金型材中空截面，给高强度下的扭转和挠度应力。

The lead rail was redesigned to make it more high strength, and the rail working face higher rigidity and higher abrasion performance according to the actual situations.
