The study is devoted to consideration of issues concerning the securing of reliability and safety of transport-technological machines in regard to tunnel escalators at the initial period of operation. Securing of operation safety of tunnel escalators is realized at three stages, namely, during the designing and production, during the period of putting into service, and at the initial period of operation. The work of expert organizations on implementation of control during the putting escalators in service, as well as on monitoring the technical condition after the operation start-up, and the methods of nondestructive control used is analyzed.
