The invention relates to the field of lifting devices, and discloses a non-differential follow-up synchronous double-cylinder lifting mechanism. The lifting mechanism comprises an oil pump (1), a reversing valve (10), a main oil cylinder (2), an auxiliary oil cylinder (3), a first oil circuit (11) and a second oil circuit (12), a main upper cavity (201) and an auxiliary upper cavity (301) communicate with each other and are connected to an outer joint A of the reversing valve (10) through the first oil circuit (11), and a main lower cavity (202) of the main oil cylinder (2) and an auxiliary lower cavity (302) of the main oil cylinder (2) communicate with each other and are connected to another outer joint B of the reversing valve (10) through the second oil circuit (12). The non-differential double-cylinder linkage follow-up design structure is adopted, the product assembly weight is reduced, meanwhile, the synchronous stable work of the lifting/falling process of a cab is realized, and the comfort requirement at the vehicle travelling state is met; and the non-differential follow-up synchronous double-cylinder lifting mechanism has the characteristics of simple structure, low cost, high production efficiency and safety and reliability, and a large application and popularization market is achieved.
