The new type of bridge crane is a new type of crane with lightweight, universal, energy-saving and environmental protection, and high technical content that our company developed on the basis of introducing and digesting advanced foreign technology, with modular design theory as the guidance, modern computer technology as the means, the introduction of optimization design and reliability design methods, and the use of imported configurations, new materials, and new processes.
The design, manufacture and inspection of this crane are in accordance with relevant national standards, and some foreign standards such as FEM, DIN, IEC, etc. are equivalently adopted. Compared with the original general QD type bridge crane products, the deadweight is reduced by about 15-30%, and the wheel pressure is reduced by about 10-35%, which can reduce the requirements of the crane on the plant structure and save the manufacturing cost of the plant. The core component of the transmission mechanism, the reducer, all adopts hardened tooth surface and high-precision gear pairs, plus the application of steel drums, forged wheels and variable frequency speed regulation systems, making this model of crane an upgraded product with excellent economic and social benefits, suitable for machinery manufacturing, assembly, petrochemical, warehousing and logistics, power construction, papermaking, railways and other industries.
Ø The main beam adopts a skewed box-type structure and is connected to the end beam with high-strength bolts for easy transportation. Specialized processing equipment ensures the connection accuracy of the main and end beams, making the crane run smoothly. Ø The hoisting trolley is an open and compact winch structure, and European hoist trolleys can also be used for small and medium tonnage.
Ø The trolley and trolley operating mechanism adopts European technology three-in-one drive form, hardened gear reducer, compact structure, low noise, no oil leakage, and long service life. Ø Due to the use of European compact trolley and high-strength materials, the overall size of the machine is small and light. Compared with traditional cranes, under the same lifting height conditions, the height of the plant can be reduced, effectively reducing the cost of the plant. Ø Modular design, short design cycle, high degree of commonality, and improved utilization of parts. Ø Compact structure, low clearance, small size, large working range, effectively improving production efficiency. Ø Full frequency conversion control, stable operation, no impact, slow speed for heavy loads, fast speed for light loads, energy saving and consumption reduction.
