Specific embodiment
The utility model is described in further detail with reference to the accompanying drawing, but not as limitations of the present invention: a kind of
Fall arrest four goes out rope electric hoist, including speed reducer used in hoisting 1, Cone-shaped electric machine 6 and four rope stretching double-helical reel devices 3, described
Four rope stretching double-helical reel devices 3 are provided between Cone-shaped electric machine 6 and speed reducer used in hoisting 1；The four rope stretching double-helical reels
It is provided with top sheave A7 and top sheave B8 below device 3, four pulley suspension hooks 9 are provided with below the top sheave B8；It is described
Four rope stretching double-helical reel devices on be provided with two mutual independent wirerope, respectively wirerope A4 and wirerope B5；
The four pulley suspension hooks 9 have been set gradually from left to right pulley 19-1, pulley 29-2, pulley 39-3 and pulley 49-4；It is described
Wirerope A4 be connected with pulley 39-3 by top sheave B8, the wirerope B5 passes through top sheave A7 and pulley 49-4 phase
Even.
The top of the four rope stretching double-helical reel devices 3 is arranged symmetrically, and there are two motor-driven carriers 2.The top sheave
