STUDIES ON THE MODERNIZATION OF LARGE CAPACITY EXCHANGERS EXISTENCE IN MINIER ROVINARI BASIN

Abstract

This paper presents improvements to parts of the excavatorERc1470/30/7, resulting in: increasing the volume of annual mines by improving the time of intensive and extensive use, lower production costs, increased operational safety, improving the quality of the delivered production, reducing the excavator's weight by replacing some subassemblies having lower weight, low power consumption, optimization of excavation capacity, ensuring the ergonomic comfort of the excavator and protection of electrical and mechanical circuits.
