The feature characterizing the method is that in an operation following the finishing of the track supporting structure, the mounting bodies are machined in a way such as to correct the structural inaccuracies caused by manufacturing tolerances of the prior art steel and concrete construction, to obtain an accurate mutual position of the equipment parts at the location of attachment. For this purpose, preferably, the mounting bodies are provided at the securing locations with bores and countersinks which are accurate in all the coordinates and correspond to the bolts or bores of the equipment parts, to finally mount these parts by means of bolts and spacer bushings. The bores and countersinks are formed by computer controlled drilling machines in a workshop where the support structures are held at a position which they will ultimately have in the field.
A method of securing equipment parts in accurate positions at predetermined locations of connection to a structure supporting a track following system of transportation, particularly a magnetic suspension railroad, comprising providing mounting bodies for the track supporting structure at locations of attachment and dimensioned for transferring to the track supporting structure forces and torques which act through a vehicle, connecting the mounting bodies at the desired attitude to the supporting structure in accordance with the layout of the track as referred to working surfaces of the parts of equipment, providing the mounting bodies after they are connected to the supporting structure with a plurality of thruholes and countersinks by drilling in a number needed for mounting the equipment part corresponding to the respective bolts and bores thereof and having the exact dimensions in all coordinates, securing equipment parts to the mounting bodies using exact dimensioned bolts received in the holes drilled therein, and laying out a plurality of the supporting structures to form a layout of the track.
A method according to claim l, wherein said track supporting structure is made of steel and wherein said mounting bodies are accessible from both sides and provided with bores and countersinks which are exact in all coordinants and including mounting the equipment parts by means of bolts, spacer bushing and nuts.
A method of securing equipment parts at accurate positions and at predetermined locations to track the supporting structures of a magnetic suspension railroad, comprising:
