Abstract
On a track for electromagnetically levitated vehicles, to adjust and secure side guide rails on a beam-like support member forming the track, after stators are adjusted and fixed to the support member, the side guide rails are held in position relative to the support member. Initially, the guide rails are positioned relative to the track and then are adjusted with respect to a datum plane determined by the lower surfaces of the stators. Next, the guide rails are adjusted horizontally transversely of the track with respect to measuring points fixed to the surface of the support member. Finally, the guide rails are attached to the support member. Apparatus for installing the guide rails includes a plurality of installation truss frames mounting assembly arms for holding the guide rails. Each assembly arm has a holding device for a guide rail and an abutment positionable against a lower surface of the stators. The installation truss frames are supported on a transport frame so that the truss frames can be moved laterally relative to the support member and adjusted in height with respect to the upper surface of the support member. Each installation truss frame supports a measuring device with a measuring head to be brought into coincidence with a measuring point located on the upper surface of the support member.
