The invention discloses a main hoisting mechanism of a metallurgy ladle crane. When the main hoisting mechanism is used, a first motor and a second motor are started, and the phase of the first motor and the phase of the second motor are adjusted through a phase adjustment device connected between the first motor and the second motor to enable the first motor and the second motor to synchronously rotate. The torque is transmitted by the output end of the first motor to the input end of a first speed reducer and transmitted by the output end of the first speed reducer to the input end of a first main hoisting drum, and meanwhile the torque is transmitted by the output end of the second motor to the input end of a second speed reducer and transmitted by the output end of the second speed reducer to the input end of a second main hoisting drum. The output end of the first main hoisting drum is connected with the output end of the second main hoisting drum through a first shaft coupler, synchronous rotation of the first main hoisting drum and the second main hoisting drum is achieved, rigid connection bolts of the first shaft coupler are prevented from being loosened and sheared, and a drum shaft is prevented from being cracked. The invention further provides the crane which comprises the main hoisting mechanism.
