Our company's new overhead crane is based on the introduction and development of foreign advanced technology, guided by the theory of modular design, using modern computer technology as a means, introducing optimized design methods and design reliability, using imported configurations, new materials and new technologies. The faucet completed by this process is lightweight, versatile, energy-saving, environmentally friendly and high-tech. The design, production and inspection of this crane comply with relevant national standards and are equivalent to some foreign standards such as FEM, DIN, IEC. Compared with the original QD type general purpose overhead cranes, the dead weight is reduced by about 15-30%, and the pressure is reduced by wheel is reduced to about 10-35% smaller, which can reduce the crane requirements on the structure of the factory building and save the production cost of the factory building. The main component of the transmission mechanism, the gearbox, uses hard tooth surfaces and high-precision gear pairs. Together with the adoption of steel drums, forged wheels and frequency conversion speed control systems, this type of crane has become an upgraded model with excellent economic and social advantages. The products are suitable for mechanical engineering, assembly, petrochemical, warehousing and logistics, energy construction, papermaking, railroad and other industries. Ø The main beam adopts off-rail box structure and is connected to the end beam with high strength bolts for easy transportation. Specialized technological equipment ensures the accuracy of the connection of the main end beam and ensures uninterrupted operation of the crane. Ø The lifting trolley is an open compact design with a winch, and the European type lifting trolleys can also be used for small and medium tonnage. Ø The working mechanism of large and small cars adopts European three-in-one drive technology, hard surface tooth gearbox, compact structure, low noise, no oil leakage and long service life. Ø Using European compact trolleys and high-strength materials, the whole machine is small in size and light in weight. Compared with traditional cranes, the plant height can be reduced under the same lifting height conditions, effectively reducing the plant cost. Ø Modular design, short design cycle, high generalization and improved parts utilization. Ø Compact structure, small height, small size and large operating range, which effectively improves production efficiency. Ø Full control of frequency conversion, smooth operation, no shock, low speed for heavy loads, fast for light loads, saving energy and reducing consumption.
