Rail Transit

Rail Transit

Qianhao Magnetic Electric's permanent magnet technology, with millisecond-level magnetic control and millimeter-level precision, is leading the intelligent transformation of rail transit equipment manufacturing. In key projects such as China Railway Construction and CRRC, its precision milling machine processed permanent magnet chucks achieve non-destructive adsorption of railway tracks, increasing operational efficiency by 40% and reducing energy consumption by 95%. The standard of "Intelligent Heavy-duty Steel Plate Transportation Line", which is led by this technology, has been deeply integrated into Tianqiao Jiacheng's 5G intelligent production line. Through magnetic force dynamic grouping control technology, it achieves millisecond-level switching between single-sheet sorting and multi-sheet stacking of steel plates, compressing the single operation cycle to within 8 seconds. The system solution, which has passed ISO9001 certification, has achieved full-process automated handling in leading enterprises such as XCMG and Zoomlion, covering 100% of core workstations, and accelerating the evolution of rail transit manufacturing towards a "dark factory". With magnetic control technology as its engine, Qianhao is reshaping the new paradigm of intelligent industrial logistics and driving China's high-end equipment manufacturing towards the top of the global value chain.
