Abstract (en)

This type of fastenings currently use five versions of elbowed plates, depending on whether the monoblock ties are for single rail tracks with profile UIC-54 or UIC-60, or for versatile ties for doble width tracks and rails UIC-54 and UIC-60, as well as having, in these latter cases, to be assembled in the interior or exterior of the rail. On these plates abut the respective cramp or elastic clip which fastens the shoe by means of the suitable screw threaded to the rail. All these plates are lightened advantageously, forming at the bottom ten transversal webs and with the central hole (11), reinforced with a circular web (with the exception of the elbowed end guide). All the plates have shorter preassembly supports for the clip (5), and the internal zone is circular, as well as having the notch with toroidal shape with greater size, which makes optimum the coupling of the central loop of the clip (5). <IMAGE>
