The aerospace industry features specially constructed plant buildings, extremely highly valued single-piece products, complicated assembly processes, extremely demanding assembly accuracy, considerable geometrical dimensions, etc., imposing high requirements on associated lifting equipment. The special multi-support structure and the multi-story frame structure dramatically increase difficulties in designing, manufacturing and installing a crane. In addition, to ensure the absolute safety and reliability of cranes, methods like enhanced quality control, increased security configuration, etc. should be followed. Meanwhile, to meet demand of assembly processes, a crane has to provide special options such as synchronous lifting, integral rotating, adjacent span rail-crossing, automatic positioning, horizontal anti-swing and inching positioning. Eurocrane products have offered services to many renowned enterprises at home and abroad, and have been widely praised for the sophisticated technology, extraordinary performance and excellent quality.
