Method for hoisting Fischer-Tropsch synthesis reactor by taking gantry crane as main crane and achieving tail lifting through single gantry

The invention relates to a method for hoisting a Fischer-Tropsch synthesis reactor by taking a gantry crane as a main crane and achieving tail lifting through a single gantry, and belongs to the installation field of chemical production equipment. The method includes the following steps that (1) the head of a barrel of the Fischer-Tropsch synthesis reactor is lifted through hydraulic lifters of the main crane step by step, the tail lifting gantry follows main lifting actions cooperatively, and then the tail of the barrel of the Fischer-Tropsch synthesis reactor is lifted and conveyed forwards; (2) in the sliding process of the barrel of the Fischer-Tropsch synthesis reactor, the ascending speeds of the two sets of hydraulic lifters of the main crane are controlled to keep consistent; and (3) along with continuous lifting actions of the hydraulic lifters of the main crane, continuously forward lifting and conveying are conducted through the tail lifting gantry. According to the method, construction cost is low and safety is achieved.
