Abstract
A hydraulic system arranged to control at least two hydraulic actuators via a metering control valve assembly. The hydraulic system is advantageous to control a pivoting arm of an undercutting mining machine according to at least two modes of operation including an idling mode and a cutting mode. In particular, the hydraulic actuators may be controlled by quantitative variation of fluid flow speed and pressure.
