China Railway Construction independently develops lifting products to fill a number of domestic gaps

On December 11, 2013, the ME150t+75-45A4 type hydropower station gantry crane independently researched and developed by Shandong Electric Construction Fenghui Equipment Technology Co., Ltd. was awarded the “2013 2013 Scientific and Technological Innovation Project Promotion Conference sponsored by the China Quality Evaluation Association”. The China Quality Evaluation Association's Science and Technology Innovation Award - Outstanding Award for Scientific and Technological Innovation Achievements.
The “ME150t+75t-45A4 gantry crane” project is a project of Shandong Province's technological innovation project. Shandong Fenghui Equipment Technology Co., Ltd. is a large gantry crane developed by a large shipbuilding company. The crane adopts pipe truss structure, the main beam adopts double beam form, double trolley layout, the rated capacity of the main trolley is 150t, the span of the trolley is 45m, and the lifting height is 39.5m. The utility model has the advantages of light weight, high working efficiency, strong wind resistance, wide application range and the like. The national-level S&T intelligence organization has conducted domestic and international scientific and technological innovations and provincial and ministerial-level scientific and technological achievements appraisal. Many of its technologies have filled gaps at home and abroad, and its comprehensive performance has reached the international advanced level.
In addition, the machine is easy to install, low power consumption, small wheel pressure, low cost of basic production and processing, low operating costs, suitable for large parts loading and unloading in docks, freight yards and other places, especially suitable for shipbuilding operations in coastal areas, energy saving and environmental protection, improve efficiency , with high social value and economic value.
In recent years, as the shipbuilding industry has become increasingly demanding for the performance of large gantry cranes, designing new types of gantry cranes needs to be comprehensively considered in terms of wind resistance, lifting capacity, structural stability, power allocation, and operation control. The ME150t+75t-45A4 type gantry crane has large span, high lifting height, independent operation of double trolleys, large lifting capacity, and difficulty in design and manufacture. During the design and trial production process, many trials have been conducted to solve large-scale tests by comparison. Gantry crane design and manufacturing problems; After the acceptance committee identified, the aircraft's main technical performance has reached the international advanced level, with independent intellectual property rights, economic and social benefits are significant.
