The invention discloses an electric hoist for a double-beam European style crane, and belongs to the technical field of cranes. The electric hoist comprises an electric appliance box, a lifting motor and a gearbox, the lower part of the electric appliance box is connected with a connecting column, the lower end of the connecting column is connected with a lifting hook, the outer surface of the connecting column is fixedly provided with a plurality of limiting mechanisms, each limiting mechanism comprises a limiting seat and a fixing plate, adjusting mechanisms are fixedly installed on the outer surface of the lifting motor and the outer surface of the gearbox, each adjusting mechanism comprises an adjusting seat and a supporting plate, adjusting ropes are connected between the limiting mechanisms and the adjusting mechanisms, and the limiting mechanisms are matched with the adjusting mechanisms and the adjusting ropes to limit the position of the connecting column in the left-right direction and used for improving the stability of the connecting column during operation. The electric hoist is used for solving the technical problem that in an existing scheme, stability is poor when the lifting hook lifts objects, and consequently the operation efficiency of the electric hoist is poor.
