The invention provides a crane and a lifting mechanism. The lifting mechanism comprises a winding engine, a plurality of pulley blocks which are connected in series through a lifting rope and are driven by the winding engine and a plurality of lifting hooks which are separately correspondingly connected with each pulley block, wherein each pulley block comprises at least one fixed pulley and a matched moving pulley, and the lifting hooks are connected with the moving pulleys. The lifting mechanism further comprises a leveling device, wherein the leveling device comprises a sensor, a processing unit and a plurality of motors; the sensor is arranged corresponding to the lifting rope and used for acquiring the speed of the lifting rope; the processing unit is electrically connected with the sensor so as to carry out calculation according to the speed of the lifting rope, detected by the sensor, and output a control instruction; the motors are electrically connected with the processing unit and output rotating movement according to the control instruction of the processing unit at corresponding rotating speeds; and the motors separately correspondingly drive the fixed pulley of one pulley block to rotate, thereby ensuring the synchronous lifting and lowering of the lifting hooks connected by the pulley blocks. The lifting mechanism can ensure the synchronous lifting and lowering of the lifting hooks in the lifting mechanism.
