The concept of the European type crane
European crane is a high-end crane, not the concept of European crane terminology, it is the summary of the domestic crane (crane user from the Soviet design and manufacturing technology) is reliable, good versatility, low price, combined with the advanced European crane advanced technology, compact structure, light weight, energy saving, low according to the noise characteristics, characteristics of the proposed Chinese gantry crane requirements, is a clear market demand, is the definition of  in the high-end new gantry crane.
The concept of the European type crane is formed in recent years. The purpose is to distinguish from the previous so-called domestic, Soviet (Soviet) type and traditional cranes. Mainly include: bridge crane, gantry crane, cantilever crane, flexible beam crane, explosion-proof crane and other industrial cranes.
Europe is the European crane lightweight and modular design concept and advanced manufacturing technology based on the structure of the whole crane has the advantages of compact structure, stable operation, reduced weight, reduced height, reduced energy consumption, greatly reduce the construction cost of the plant and the user operation of the crane crane operation cost, improve the quality and performance of the crane. The European crane will become the main trend of the development trend and market demand of the crane.
1, the main beam adopts square box type H steel structure design, which is similar to the traditional simple driving, and the weight is heavier.
2, the main weld of the main weld is nondestructive.
3. The steel sheet material is the domestic steel (Q235B).
4, the vertical winding degree is according to the national standard of China.
5. All steel plates, like the traditional crane in our country, are pretreated by shot blasting to reach the standard of Sa2.5.
6, careful inspection and cleaning before welding steel plate welded by automatic welding machine, usually performed (MIG or semi automatic welding);
1, the end beam is welded by rectangular steel tube or steel plate. After forming, the end beam will be processed at one time in the numerical control machine tool to reach the allowable deviation range, so as to ensure the national dimension accuracy and fit tolerance.
2. Each end beam is equipped with a wheel, a buffer and an anti - derailment protection device with a double rim.
3. The double beam crane is equipped with a maintenance platform (maintenance aisle) on the driving side of the main girder.
4. The main beam and end beam are connected with high strength bolt to ensure the accuracy and smooth operation of the whole machine.
