[0014] Fig. 1 is a structural schematic view of the utility model.

[0015] Fig. 2 is a side view of the utility model. DETAILED DESCRIPTION

[0016] The utility model will be further described below with reference to the drawings.

[0017] As Figs. 1-2 shown, a novel compact electric hoist with a new Chinese style, including two opposite mounting plate 1, 1 between the mounting plate 0 set up winding drum 5 mechanism 2, winding drum 5 mechanism 2 includes mounting frame 3, the two sides of mounting frame 3 are provided with four rectangularly arranged lug plate 4, lug plate 4 and mounting plate 1 are locked and fixed by bolt and nut, lug plate 4 is convenient for winding drum 5 mechanism 2's loading and unloading, is favorable to the maintenance and overhaul of winding drum 5 mechanism 2. Winding drum 5 is rotatably connected in mounting frame 3, one side of mounting frame 3 is provided with driving motor 6, driving motor 6 drives winding drum 5 to rotate, winding drum 5 below is connected with lifting hook 7 through steel wire rope, lifting hook 7 is provided with movable pulley, one end of steel wire rope is wound on winding drum 5, the other end of steel wire rope is wound after movable pulley, and is fixedly connected in the middle of mounting frame 3.
