The invention relates to the technical field of cranes, in particular to a modular European-style single-beam electric hoist which is characterized in that a rack comprises a horizontal plate, side plates on the two sides of the top face of the horizontal plate and end plates fixed to the bottom face of the horizontal plate, a winding drum is arranged between the end plates, and supporting wheels are installed on the rear side plates; the driving wheel comprises an idler wheel installed on the front side plate and driven gears on the outer side of the idler wheel, and the transmission gears are arranged on two side shafts of the T-shaped reverser in a sleeving mode and meshed with the corresponding driven gears. The conversion transmission piece comprises a box body, a front shaft piece rotationally arranged on the front wall of the box body in a sleeving mode, a rear shaft piece rotationally arranged on the rear wall of the box body in a sleeving mode and in butt joint with the winding drum shaft body, a top shaft piece in butt joint with an input shaft at the bottom end of the T-shaped reverser, an adjustable shaft piece slidably arranged on the front shaft piece in a sleeving mode and matched with the rear shaft piece in a transmission sleeving mode, and an electric push rod. A first bevel gear at the bottom end of the top shaft piece is meshed and matched with a second bevel gear in the middle of the adjustable shaft piece, and the output end of the main drive motor is in butt joint with the front shaft piece. The problems that an European-style single-beam electric hoist is large in number of overall accessories and large in dead weight are solved.
