Construction equipment having an electric control lever is provided, which can intercept a control signal applied to a flow control valve when trouble occurs in the electric control lever or a control unit. The construction equipment includes 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 when an error occurs in the manipulation signal, an electronic flow control valve installed in a flow path between the hydraulic pump and the hydraulic actuator and shifted, by signal pressure input in proportion to the manipulation signal, to control a start, a stop, and a direction change of the hydraulic actuator, a control unit having an operation unit operating a control signal that corresponds to the manipulation signal, and a current driving unit controlling current so that a current value corresponding to the control signal can be applied to the electronic flow control valve, and a power control unit intercepting current 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.
