High speed railway technology, full name of high-speed railway technology, refers to all science and technology related to high-speed railway system, including railway construction technology, train manufacturing technology, information acquisition technology, dispatching control technology, operation management technology and maintenance technology. High speed rail technology, like aviation technology, is a huge and complex engineering system, which can not be generalized unilaterally.

The reducer used in high-speed rail production line can be divided into the following types: {K series bevel gear helical gear reducer} {F series parallel shaft helical gear reducer} {gear reducer} {screw hoist} {lifting platform of lifting system} {Shenyang Hengyu Guoqiang reducer factory}
