Construction machine

A construction machine able to translate according to a longitudinal axis with respect to a reference plane, comprising at least a base, an active member and a first rotary actuator having two ends, a first of the two ends of the first rotary actuator being rigidly fixed to the base and a second of the two ends of the first rotary actuator being rigidly fixed to the active member, the second end of the first rotary actuator being mobile in rotation about a first rotation axis parallel to the reference plane with respect to the first end of the first rotary actuator, wherein the first rotary actuator is an electrical rotary actuator comprising an electric motor intended to be supplied in electrical power by an electrical power source and deliver a rotational force to the active member in a first rotational direction and a second rotational direction, opposite the first rotational direction, about the first rotation axis depending on a command provided by a control unit to the first rotary actuator.
