The utility model relates to a crane auxiliary wheel device comprising a bracket, a roller, an encoding component and an adjustable supporting component, wherein the encoding component is electrically connected with the roller, the adjustable supporting component comprises a positioning plate, a vertical column, a pressing sleeve and a spring, the positioning plate is horizontally fixed above the bracket, the vertical column is vertically fixed on the positioning plate, the spring sleeves the vertical column, the height of the spring is more than that of the vertical column, the pressing sleeve sleeves the spring and is elastically connected with the vertical column, and an adjusting bolt is arranged above the pressing sleeve. The crane auxiliary wheel device disclosed by the utility model can be used for effectively playing a good auxiliary effect on the operation of a crane by performing monitoring and measurement on strokes by using an encoder; the integral structure of the crane auxiliary wheel device adopts independent spring design, so that a phenomenon that the balance of the entire structure can be influenced because one spring is in failure or is damaged after a plurality of springs are adopted can be prevented; and a supporting system adopts height-adjustable structure design, so that better matching between the roller and a track can be facilitated, and thus the working state of the whole device can be stable, and accidents can be prevented.
