PURPOSE: A hydraulic circuit for construction equipment is provided to minimize power loss of construction equipment by independently supplying hydraulic fluid to equipment, and to precisely control the position of the equipment. CONSTITUTION: A hydraulic circuit for construction equipment comprises a first control valve(130) for a first work, a first control valve(150) for a second work, a second control valve(140) for the first work, a second control valve(160) for the second work, and a separation unit(170). The first control valve for the first work and the second control valve for the second work control the flowing direction of hydraulic fluid supplied to a first working machine(110). The first control valve for the second work and the second control valve of the first work control the flowing direction of hydraulic fluid supplied to a second working machine(120). The separation unit switches the second control valves to neutral positions(141,161) or transfer positions(142,162,163). |
