Abstract

Trattasi di una Forca Posacentine atta ad effettuare, in una galleria in costruzione, il montaggio della centine.Tale Forca Posacentine comprende, una struttura scatolata, supportante, sui lati destro e sinistro, due denti corti e, nel centro, quattro denti lunghi.Il corpo sopracitato supporta, sui lati destro e sinistro, un pistone oleodinamico blocca centina, e, nel centro, uno zoccolo, mosso da un pistoncino, che serve come riscontro alla chiave della centina.La Forca Posacentine è solidale, nella sua mezzeria, con un sistema sferico femmina, il quale accoglie, in modo non sfilabile, un sistema sferico maschio, solidale, mediante il suo codolo, ad un braccio in lamiera scatolata.This is a Forca Posacentine designed to carry out the assembly of the ribs in a tunnel under construction. This Forca Posacentine includes a box-like structure supporting two short teeth on the right and left sides and four long teeth in the center. the aforementioned body supports, on the right and left sides, a hydraulic piston that locks the rib, and, in the center, a base, moved by a piston, which serves as a reference to the key of the rib. female spherical system, which houses, in a non-removable way, a male spherical system, integral, by means of its tang, with a boxed sheet arm.
