REMOTELY CONTROLLED DEVICE FOR MEASURING RECTILINEARITY OF RUNNING TRACK RAIL, IN PARTICULAR THOSE OF OVERHEAD TRAVELLING CRANE TRACKS

摘要

1. The remotely-controlled device for measuring rail rectilinearity is designed especially for bridge rails. It is equipped with a measuring element, secured on a shield. The latter rests on a platform with two horizontal rollers and is joined to clamp scissors with four vertical rollers. It is characterised in that an electric motor (1) is placed on a driving platform (6), joined to the platform (8) with an articulated joint (7).
