Some Aspects of Maintaining Inclined Tunnel Escalators in St. Petersburg

Abstract:

The authors of the article discuss some aspects of inclined tunnel escalators in St. Petersburg metro, related to the aging of the equipment and the necessity of its replacement in accordance with the new regulations; they propose some options for solving the existing problems. Secure work of escalators could be achieved and maintained by two ways: by designing new models of escalators with modern technologies at the basis, as well as by constant control over existing escalators working conditions during exploitation period. Authors show that the introduction of new regulatory requirements has asked for improving the design of escalators with the decrease of their lateral dimension in order to accommodate four machines in a tunnel. Authors also proposed methods of examining technical conditions of escalators at the final stage of their service life with the aim of extending it as well as for periodic evaluation of their technical condition using magnetic and magneto-acoustic technology in addition to the usual procedures.
