The invention relates to a lifting mechanism and belongs to the field of engineering equipment, in particular to a mining excavator lifting mechanism. The mining excavator lifting mechanism comprises a primary speed reduction drive mechanism, a secondary speed reduction drive mechanism and a motor, the non-load end of the motor is provided with a brake, and the load end is connected with the primary speed reduction drive mechanism through a coupling. Because the mining excavator lifting mechanism uses a single-motor single-winding drum structure and two hoisting ropes, the diameter of each hoisting rope is small, the diameter of the lifting winding drum is small, the drive ratio is reduced, the whole mechanism is simple in structure, light in weight, small in volume, less in drive piece number and small in processing and assembly workload, and the manufacturing cost is greatly lowered.
