METHOD OF AND MACHINE FOR MOUNTING CONTACT SYSTEM Russian patent published in 2003 - IPC

FIELD: electric traction. SUBSTANCE: according to proposed method of mounting of contact wire or carrier cable of electric contact system, contact wire pulled by means of guide roller at mounting height is wound off at preset tension from storage reel found of machine. Pressure applied by pressure member to stretched contact wire decreases in transition stage from standing0still, position of machine to its working position, i.e. forward movement. During transition stage from working position of machine, i.e. its forward movement, to standing-still position, pressure of pressure member increases correspondingly. Invention makes it possible to prevent inequality of tension of aerial contact wire and to create machine preventing changes in tensioning of wire at starting from place and stopping. EFFECT: improved reliability of contact system mounting. 5 cl, 3 dwg
