The invention discloses a fixed column type cantilever crane having ingenious folding and storing functions. The fixed column type cantilever crane comprises a fixing seat, an installation disc, a fixing shaft, a positioning sleeve, supporting plats, pulleys, a fixing housing, a stepping motor, a gear, a lifting column, a positioning plate, a rotary shaft and a cantilever beam. According to the fixed column type cantilever crane having the ingenious folding and storing functions, firstly, electric lifting and a rotary shaft rotating mechanism cooperate with each other, the cantilever beam canbe conveniently rotated from a horizontal state to a vertical state in the lifting process, or from the vertical state to the horizontal state, and ingenious switching between the storing state and the using state is achieved; secondly, the fixing seat and the positioning sleeve can vertically stand or be rotated and laid flat, after the installation disc is fixed to the ground, only the positioning sleeve is rotationally lifted up, vertical standing of the cantilever crane can be achieved, and convenience and efficiency of installation operation are improved; and finally, by adopting the pulley assisting mode, workers can conveniently and directly pushes the cantilever crane to be transferred. In conclusion, the fixed column type cantilever crane is convenient, practical and capable of being applied and popularized in the industry advantageously.
