Abstract
A device for controlling a breaker in construction vehicles is disclosed. The device includes a control circuit provided with a power supply, a first solenoid valve used for controlling the breaker, and a second solenoid valve used for boosting the relief pressure of the circuit. The device also includes a control switch and a select switch. The control switch is installed in a control lever and is handled by an operator in order to selectively open or close the control circuit. Meanwhile, the select switch is connected between the control switch, power supply and first and second solenoid valves. The select switch selectively connects the power supply to the first or second solenoid valve in order to select either of the breaker and pressure boosting operations, which are commonly controlled by the control switch.
