DUAL PRESSURE LOGIC FOR A TRACK DRILL CIRCUIT

A hydraulic circuit (38, 54) may be used for controlling a plurality of hydraulic implements (36, 50, 52). The hydraulic circuit (38, 54) may include a first directional valve (66), a second directional valve (64), and a relief valve. A variable displacement pump (42) (42) may be fluidly coupled to...

Zusammenfassung:	A hydraulic circuit (38, 54) may be used for controlling a plurality of hydraulic implements (36, 50, 52). The hydraulic circuit (38, 54) may include a first directional valve (66), a second directional valve (64), and a relief valve. A variable displacement pump (42) (42) may be fluidly coupled to the first directional valve (66), the second directional valve (64), and the relief valve. The hydraulic circuit (38, 54) may be communicably and operably coupled to a controller, and the controller (56) may be programmed to selectably control the hydraulic circuit (38, 54) between a first operational mode (60) and a second operational mode (62). Additionally, the controller (56) may be programmed to actuate the first directional valve (66) between an open position and a closed position and to actuate the second directional valve (64) between a first open position, a second open position, a first closed position and a second closed position.
