The invention relates to the technical field of electric chain hoists, in particular to a large-tonnage electric chain hoist structure. The device comprises a box body, a motor is arranged in the left end of the box body, fan blades are arranged at the front end of the motor, the rear end of the motor is connected with a clutch through a coupler, the other end of the clutch is connected with a gear assembly, a brake is arranged at the bottom of the left end of the gear assembly, and a chain wheel is connected to the right end of the gear assembly through a connecting shaft. A chain guide matched with the chain for transmission is arranged beside the chain wheel, and the chain is wound on the chain wheel. The electric chain hoist has the beneficial effects that the brake is matched for braking, the space is saved, and the electric chain hoist is suitable for different electric chain hoists. The clutch is directly connected with the motor, rotation of a rotor of the motor is not affected by the clutch, the clutch does not slip, and therefore the probability that the motor breaks down is reduced, and the service life is prolonged.
