Electric hoist with symmetrical mechanisms

The invention discloses an electric hoist with symmetrical mechanisms. The electric hoist comprises motor mechanisms, a fixing mechanism and a hoisting mechanism, the hoisting mechanism is arranged inthe fixing mechanism and penetrates through the fixing mechanism to be assembled with the motor mechanisms, the motor mechanisms are arranged on the two sides of the fixing mechanism and are symmetrical about the fixing mechanism, and an eccentric mechanism is also arranged in each motor mechanism. According to the electric hoist, double stators and double rotors which are of symmetrical structures are adopted, so that the weight of the whole electric hoist can be evenly distributed, and the gravity center can be easily kept at the chain wheel position; the stators and the rotors are of super-flat structures, the size is small, and super-high torque density output can be generated; and the eccentric mechanisms are arranged, when motors work, although eccentricity exists, the eccentric distance is almost kept unch
