Rational mechanical characteristic of the carriage feed drive of the AMS unit

Abstract

The AMS unit (mechanized aggregate with shandoor support), developed by SCTB Glavtonnelmetrostroy, is designed for complex mechanization of single-wall tunneling of metro stations. The AMS unit, which is a modernization of the AMK-I (K - calotte) unit, which worked in 1984 during sinking of the upper vault of Prospect Bolshevikov station, was manufactured in 1988 at Proletarsky Zavod by order of Lenmetrostroy. This is the first mining machine in the Russian practice, where along with the use of hydraulic drive in its feed mechanisms the electro-hydraulic drive of the actuator was used.
