Core technology: design and manufacturing capabilities of hydraulic systems, design and manufacturing capabilities of electrical control systems, and design and development capabilities of large steel structures. The reliability and advancement of the hydraulic system and the electronic control system have always kept pace with the international and are in a leading position in China.
Comprehensive research and development capabilities: with large ports, building materials and other areas of steel structure and transmission design experience. At the same time, it is also the only R & D enterprise in the industry that can integrate mechanical, hydraulic and electrical design. This integrated design and manufacturing can better ensure the overall performance and stability of the equipment. We have also designed a large number of port bridge cranes, portal cranes, container quay bridges, ship loaders, ship unloaders, large stacker and reclaimer and other heavy equipment, and have accumulated rich design experience. At present, the stacker-reclaimer used in many 10,000-ton cement production lines in the cement industry are all designed and manufactured by Shida Company, such as huaxin cement 2*5000t/d production line, Zhonglian cement Lunan 2*5000t/d production line, Qingzhou Zhonglian 2*6000t/d production line and Huizhou Everbright 2*5000t/d production line.

Using the current international steel structure and transmission design of the latest standards, all the application of finite element principle for mechanical analysis, while assisting ANSYS structural analysis software for computer optimization design. The overall structure of the equipment is reasonable, and the safety and reliability are significantly improved (compared with the traditional mechanical design principle).
All designers have more than 10 years of experience in large-scale mechanical design in the field of ports and building materials. The project design leaders are all outstanding graduates from well-known domestic universities (Shanghai Jiaotong University, Dalian Technology, Tongji, etc.). They have rich experience in large-scale equipment design and have a full understanding of the existing stacker-reclaimer structure abroad and at home. All these provide a strong guarantee for our leading technology and advanced products.
Since the stacker-reclaimer is a non-standardized equipment, it provides us with the opportunity to tailor the most suitable product for each customer. The stacker-reclaimer's stacker capacity can be adjusted steplessly within a certain range according to customer requirements, and the most suitable working capacity can be selected simply and conveniently.

Other major outsourcing equipment are products of major domestic well-known enterprises.
Processing and production equipment capacity is strong, the overall production standards and production level far exceed the cement building materials industry machinery and equipment processing and production standards. Our own quality management system is very perfect and standardized, in the production process to set a number of stop points, so that we strictly control the production of every link. The welding of the equipment, the processing accuracy, the pretreatment of the plate and the overall appearance are perfect. Taking the processing of the central column of the circular stacker-reclaimer (including: base, middle column, ring beam, upper and lower turntables) as an example, its components are large in volume and require high welding and processing accuracy (coaxiality, levelness). Therefore, after the assembly and welding of the components are completed, the whole is annealed in the furnace to eliminate the welding stress, and then processed, so as to ensure the stable operation of the equipment after installation. General processing enterprises do not have such large-scale equipment, large components can not be integrated into the furnace annealing, only natural cooling annealing in the air, so it is difficult to eliminate the welding stress in a short time, resulting in the equipment in the installation and operation of the release of stress, resulting in equipment deformation, to bring hidden dangers to safe operation.
