ESFAHAN DOR MOTOGHAYER Complex (Private Joint Stock) was established in 1981- the important activities of this producing unit are as follows: Designing and manufacturing of light and heavy industrial gearboxes with different efficiencies, designing and manufacturing industrial gear, offering after sale services, servicing and restructuring different gearboxes produced by this complex and producing above-mentioned sets outside the country. This center has proceeded to hire and instruct young and efficient man powers and took steps to design and manufacture a new generation of industrial gearboxes with high efficiency in the form of solar gearboxes. Economically this proceeding has resulted in not paying any exchange currency to foreign countries and technically caused reducing power waste and enhancing output efficiency and consequently reducing electricity power consumption. The most important strategy of the complex is to produce products with high quality and quantity based on world standards for heavy consumption of steel and cement industries and factories these products have small dimensions comparing to similar samples resulting from their output efficiency. This property has caused consumers to use the products more easily in their planning. Also for attracting customer’s satisfaction and allocating ourselves a great share of market, we proceeded to manufacture different gearboxes based on customers’ orders in different intended dimensions and sized. Consumers of gearboxes proceeded to customize the kinds of inlets and outlets regarding their needs and the location for placing the sets. This issue lonely has caused that consumers have no concern regarding planning and using special inlets and considering the materials and status quo, proceeded to order these products. Among other strength of these products, we can refer to variety in the gearbox revolution proportion. The "ESFAHAN DOR MOTOGHAYER" has been renamed "SHAHBAZ GEARBOX PISHRO SEPAHAN" in 1396. This kind of gearbox can sometimes reduce its output revolution to less than 1 turn due to stepwise planning. The last and newest product of this complex is solar gearbox type sh20000 whose moment reaches to 40000 N. m. Authorities and practitioners of this complex have intended to be present in world markets by relying on great God and support of their valuable experiences, development of their products, variety of products in harmony with world new technology and developing proper aspects and continue their efforts to reach to relevant objectives. In this vein considering the needs of other countries, this complex will proceed to export its products to other countries in a very new future and thus raises Iran flag on the success climax like before.
