The QU70 rail is a load-bearing rail specifically designed for 50–100 ton bridge and gantry cranes. It complies with the Chinese metallurgical industry standard YB/T 5055-2014 and is rolled from special steels such as U71Mn or U75V. QU70 is a specific size within the QU series of crane rails, adhering to Chinese standards. The "70" refers to the width of the rail head; thus, the QU70 rail has a head width of 70 mm.
Kingrail Parts supplies not only QU70 rails compliant with Chinese standards but also other crane rail sizes—such as QU80, QU100, and QU120—along with matching fasteners like crane rail clips and crane bolts.
