Abstract A small diameter rolling pillar is equipped on the working platform of traditional line erecting car with “low temperature and high platform” for supporting contact wire and making it turning during the construction of line erecting. In this way, a great tuning contact wire is only supported by one point and it can make the wire hard bending easily undei some conditions,which can not meet requirement the electrified railway line with speed above 140 km/h, so a new auxiliary supporting device of anti-hard bending for overhead line erecting is put forward.
