As a power transmission gear mechanism, the gear reducer drive by the speed converter, turn the motor speed decelerated to a desired number of rotations and obtain a larger torque at the same time.
According to one Industry Market Research Center, the most industries which is using gear drives are: electrical machinery, metallurgical machinery, environmental protection machinery, electronic appliances, road construction machinery, chemical machinery, food machinery, light machinery, mining machinery, transportation machinery, construction machinery, building materials machinery, cement machinery, rubber machinery, hydraulic machinery, petroleum machinery, etc. and all these industries accounted for 60% to 70% of all.

With the rapid development in recent years, the domestic economy, the heavy machinery industry exports increased, as an important basis for the development of the industry reducer industry extraordinarily rapid. Reducers Enterprise is toward the expansion of production scale, processing capacity and technology continued to improve development. Reducer future market prospects for the industry will be bright
In the heavy machinery market demand increase, the industry is also product upgrades, integration of the two aspects of energy conservation fruitful work. The upgrading of products, years of the same old product in accelerating the pace of technological update. Gantry crane industry enterprises to adopt a joint or independent way of development, we have the old product innovation, product upgrades of the formation of the industry boom. Beijing Materials Handling Research Institute jointly carried out many enterprises bridge crane series lightweight work, now made progress. Industry actively introduce Frequency transmission technology, remote control and information technology, accelerate the upgrading of products to high-end technology. Industry development crane gearless variable frequency drives began to test the water main lifting device in the market.

International market demand for heavy machinery and equipment and spare parts will also increase. With the gradual recovery of the national economy in Europe and America, to re-establish the status of the real economy in the national economy, and infrastructure needs of developing countries, heavy machinery will be more room for development in the international market.
