However, the positioning of the standard section is rather troublesome and the efficiency is slow during the cutting process. For this reason, we propose an auxiliary device for a cutting wire for processing tower crane standard sections, which is used to assist the cutting wire to cut the tower crane standard section more quickly and accurately.
