HYDRO-SYSTEM FOR CONTROLLING CATERPILLAR DRIVE OF MINING MACHINE Russian patent published in 2006 - IPC E02F9/22 

FIELD: mining industry, mechanical engineering, possible use in system for controlling caterpillar drive of mining machine.

SUBSTANCE: hydro-system contains pumps for caterpillar drive and pump, feeding system of working functions of machine, hydro-distributors for controlling caterpillar drive, driving hydro-motors and working mains, two controllable check valves and hydro-distributor for controlling system of machine working functions. Outlet channels of hydro-distributor for controlling system of machine working functions are connected to inlet channels of controllable check valves, which are connected between each other. Outlet channels of these valves are connected to working mains of driving hydro-motors and hydro-distributors for controlling caterpillar drive.

EFFECT: possible movement of mining machine in case of breakdown of driving pumps at the expense of influx of working liquid from pump driving system normally used for working functions of machine.
