The invention relates to a method for replacing a luffing oil cylinder of a luffing tower crane and the luffing tower crane, and the method for replacing the luffing oil cylinder of the luffing tower crane comprises the following steps: hoisting the luffing oil cylinder needing to be disassembled by using an auxiliary hoisting device on the luffing tower crane, and disassembling the luffing oil cylinder needing to be disassembled; an auxiliary lifting device on the movable arm tower crane is used for enabling the variable-amplitude oil cylinder needing to be disassembled to penetrate out to the bottom of the cargo boom; a lifting mechanism of the movable arm tower crane is used for descending the variable-amplitude oil cylinder needing to be disassembled to the ground; a to-be-installed variable-amplitude oil cylinder is lifted to the position below a cargo boom through a lifting mechanism of the movable arm tower crane; penetrating the variable-amplitude oil cylinder to be mounted into the cargo boom by using an auxiliary hoisting device on the movable arm tower crane; and an auxiliary hoisting device on the movable arm tower crane is used for hoisting the variable-amplitude oil cylinder to be installed, and the variable-amplitude oil cylinder to be installed is installed on the movable arm tower crane. In the embodiment of the invention, the variable-amplitude oil cylinder can be directly disassembled and assembled, the disassembly and assembly are convenient, time and labor are saved, and additional hoisting equipment is not needed, so that the cost is saved.
