A construction equipment including an engine, a hydraulic pump and a pilot pump which are driven by the engine, and a hydraulic actuator which is operated by the hydraulic pump, the construction equipment comprising: an electric control lever outputting a manipulation signal in proportion to a manipulation amount; a manipulation locking lever outputting a manipulation signal for control in preference to the manipulation signal of the electric control lever when an error occurs in the manipulation signal of the electric control lever; an electronic flow control valve installed in a flow path between the hydraulic pump and the hydraulic actuator and shifted, by signal pressure that is provided by electro-proportional valves (8, 9) in proportion to the manipulation signal of the electric control lever, to control a start, a stop, and a direction change of the hydraulic actuator; a control unit having an operation unit operating and outputting a control signal that corresponds to the manipulation signal of the electric control lever; and a power control unit, characterized in that the control unit comprises a current driving unit controlling current so that a current value corresponding to the control signal operated by the operation unit can be applied to the electronic flow control valve; the power control unit intercepts current that is applied from the current driving unit to the electronic flow control valve when the manipulation locking lever is manipulated in a state where trouble has occurred in the electric control lever or the control unit; the current driving unit comprises a PWM driving unit; the power control unit includes a switch installed on the manipulation locking lever; the power of the PWM driving unit is connected to the PWM driving unit through the switch of the manipulation locking lever; and when the manipulation locking lever is in a manipulation locking state, the power of the PWM driving unit is intercepted, and thus the current flow to the electro-proportional valves (8, 9) is intercepted. an electric control lever outputting a manipulation signal in proportion to a manipulation amount; a manipulation locking lever outputting a manipulation signal for control in preference to the manipulation signal of the electric control lever when an error occurs in the manipulation signal of the electric control lever; an electronic flow control valve installed in a flow path between the hydraulic pump and the hydraulic actuator and shifted, by signal pressure that is provided by electro-proportional valves (8, 9) in proportion to the manipulation signal of the electric control lever, to control a start, a stop, and a direction change of the hydraulic actuator; a control unit having an operation unit operating and outputting a control signal that corresponds to the manipulation signal of the electric control lever; and a power control unit, characterized in that the control unit comprises a current driving unit controlling current so that a current value corresponding to the control signal operated by the operation unit can be applied to the electronic flow control valve; the power control unit intercepts current that is applied from the current driving unit to the electronic flow control valve when the manipulation locking lever is manipulated in a state where trouble has occurred in the electric control lever or the control unit; the current driving unit comprises a PWM driving unit; the power control unit includes a switch installed on the manipulation locking lever; the power of the PWM driving unit is connected to the PWM driving unit through the switch of the manipulation locking lever; and when the manipulation locking lever is in a manipulation locking state, the power of the PWM driving unit is intercepted, and thus the current flow to the electro-proportional valves (8, 9) is intercepted.
