The invention discloses a stand column type folding arm crane. The stand column type folding arm crane comprises a stand column, a main arm, an auxiliary arm and a hoisting mechanism, the stand column is vertically arranged. The main arm is rotationally connected to the stand column and transversely extends. The auxiliary arm is connected with the main arm through a first rotating mechanism and transversely extends. And the hoisting mechanism is arranged on the auxiliary arm. The first rotating mechanism comprises a first bearing piece, a second bearing piece, a rotating disc, a first rotating shaft, a connecting piece, a fixing disc, a control disc and a control piece. The first bearing part and the second bearing part are fixed to the upper side and the lower side of the auxiliary arm respectively and extend to the upper side and the lower side of the main arm, the connecting part vertically penetrates through the main arm, the rotating disc is arranged on the bottom side of the first bearing part and connected with the upper end of the connecting part through a first rotating shaft, and the fixing disc is arranged at the lower end of the connecting part and located on the upper side of the second bearing part. And a control disc and a control piece are sequentially arranged on the second bearing piece on one side of the fixed disc. According to the stand column type folding arm crane, the swing sensitivity of the auxiliary arm is controlled through the cooperation of the control piece and the control panel.
