Manufacturing Process of EOT Cranes
The manufacturing process of double girder EOT cranes involves several critical steps, ensuring high precision and quality.
1. Preparation Before Manufacturing
Before manufacturing begins, detailed drawings are created based on contract requirements. Materials are delivered to the site, and quality inspections are conducted to ensure compliance with specifications.
2. Steel Treatment
Steel coils are uncoiled, flattened, and treated to remove rust. This process enhances the quality of the steel, ensuring durability and longevity.
3. Material Preparation and Cutting
Web plates, cover plates, and stiffening plates are cut using CNC plasma cutting machines. This ensures precise dimensions and quality, which are crucial for the structural integrity of the crane.
4. Assembly and Welding
The assembly of the box-type beam involves welding the upper cover plate to the stiffening plates and web plates. This step is critical for ensuring the strength and stability of the crane.
5. Repair and Inspection
After assembly, the main beams undergo inspection for camber, waviness, and other structural integrity checks. Any discrepancies are corrected to meet safety standards.
Conclusion
The double girder EOT crane manufacturing process is a complex yet essential procedure that ensures the production of high-quality cranes capable of handling heavy loads safely and efficiently. Companies like Henan Kuangshan Crane, Kranemfg, and Aicrane are at the forefront of this industry, providing innovative solutions tailored to meet the diverse needs of their clients.
