The invention discloses a head four-rope hoisting wheel group. The head four-rope hoisting wheel group comprises an end part mounting arm frame, a first supporting shaft and a second supporting shaft, wherein the first supporting shaft and the second supporting shaft are symmetrically arranged on the end part mounting arm frame; the axes of the first supporting shaft and the second supporting shaft are overlapped and a gap is formed between the first supporting shaft and the second supporting shaft; the first supporting shaft is provided with a first hot rolling pulley and a second hot rolling pulley at interval; the second supporting shaft is provided with a third hot rolling pulley and a fourth hot rolling pulley at interval; and four pressing wheels, which correspond to outer circle wheel grooves of the first hot rolling pulley, the second hot rolling pulley, the third hot rolling pulley and the fourth hot rolling pulley respectively, are arranged on the end part mounting arm frame. By virtue of the manner, the head four-rope hoisting wheel group is provided with two groups of the pulleys, namely four pulleys, and is convenient to mount and maintain; a grab bucket can be conveniently mounted and the hoisting stability of the grab bucket is good; and the time of replacing a rope is saved and the working efficiency is improved.
