KTS AZS Chocking System is designed for automation of precise stopping and train chocking on reception and departure tracks on railway stations. It employs stationary heavy-duty braking chocks consisting of two modules – chocking and absorbing modules. The modules are installed on reception and departure tracks – one set for each track, except main tracks and tracks designated for non-stop passing.
A train is chocked by electromechanically driven elements of the braking chock that change their position by an operator's command providing mechanical effect on rolling stocks' wheel pairs. The system prevents accidental movement of chocked rolling stock or its any part.
