The invention provides a large-lifting-height electric hoist which comprises a fixing frame and a driving component, and the driving component is arranged at one end of the fixing frame. The main winding drum is connected with the driving component, and power generated by the driving component drives the main winding drum and the driven winding drum to rotate synchronously; a first movable pulley and a second movable pulley are respectively arranged at two ends of the lifting hook; one side of the steel wire rope penetrates through the first movable pulley, the fixed pulley and the second movable pulley, and meanwhile the two ends of the steel wire rope are connected to the main winding drum and the driven winding drum respectively; when the main winding drum and the driven winding drum synchronously and reversely rotate, the two ends of the steel wire rope can be synchronously released or withdrawn, and under cooperation of the fixed pulley, the first movable pulley and the second movable pulley, the steel wire rope drives the lifting hook to ascend and descend; when the lengths of the main winding drum and the driven winding drum are equal to the length of the single winding drum, the lifting height of the single winding drum is twice that of the single winding drum.

    本发明提供了一种大起升高度电动葫芦,包括:固定架和驱动部件,所述驱动部件设置于固定架的一端;主卷筒和从动卷筒,所述主卷筒与驱动部件连接,所述驱动部件产生的动力驱动主卷筒和从动卷筒同步转动;吊钩,所述吊钩两端分别设有第一动滑轮和第二动滑轮;所述定滑轮和钢丝绳,所述钢丝绳一侧穿过第一动滑轮、定滑轮和第二动滑轮,同时所述钢丝绳的两端分别连接在主卷筒和从动卷筒;本发明所提供的主卷筒和从动卷筒同步反向转动时,所述钢丝绳的两端会同步释放或者收回,在定滑轮、第一动滑轮和第二动滑轮配合下,所述钢丝绳驱动吊钩上升和下降;当主卷筒和从动卷筒的长度与单卷筒长度相同时,能够达到单卷筒2倍起降高度。
