1. Adopt self-owned patent computer –aided design software, carry out safety margin optimized design for the whole hydraulic support and greatly increase the service life.
2. Adopt three-dimensional design to the main force components such as top beam, shield beam, base, connecting rod, pillar and perform CAE static analysis and fatigue analysis.
3. It makes the overall deformation of SANY hydraulic powered support remain in small size, little residual stress and greatly enhances reliability with adopting good quality of structure component, advanced reliable high-strength steel plate welding techniques and heat processing technology.
4. The high-strength steel plate welding in structure component is adopted to ensure the intensity of structure component.
5. The imported products are adopted in hydraulic valve and high-pressure hose to ensure the reliability of the product.
6. Refer to the mechanical engineering quality standards on precision production and appearance quality, components and pipeline shall be figured out clean and reasonably, being easy to maintain.
7. Be suitable to the integrated mechanical coal mining working surface of thick -seam coal layer and overall height mining in one time.
