Abstract

The present application describes a barrier mechanism for level crossing control systems.This new mechanism presents a set of differentiated requirements and solutions, whereby the main distinctive characteristic is the boom balance system which does not use the conventional counterweights, resulting in a reduction in the operational space of the barrier, avoiding possible accidents with workers and passers-by, minimizing as well the material damages.To achieve the indicated objective, guaranteeing the balance and stability in the movement of the boom a set of compression springs is used which exert more, or less, force on the main shaft according to the position in which the boom is found. Another important characteristic of the barrier lies in the mechanics and the transmission systems used, which present high levels of reliability.
