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. For the support provided with strong ability to escape, the phenomenon as well as crushing death on the support can not easily appear, and the base pressure is also very small and non-binding.
7. Single support equipped with independent driving device can be controlled remotely and is provided with strong flexible and adaptation ability in moving under coal mine.
8. Be suitable for room-and-pillar short-walled mining coal pillar recovery surface and even provided with good adaption to continuous miner and transport systems and high productivity.
