ABSTRACT:
An earth-moving vehicle includes a carriage, which can move on a terrain in mutually opposite directions of movement along a longitudinal axis of the vehicle, and a station for driving and maneuvering, which is able to rotate with respect to the carriage about a vertical axis, houses a plurality of controls, and is oriented in a direction in which an operator is facing during maneuvering of the controls. The vehicle is further provided with a signaling device and with a control assembly, which activates the signaling device to warn, outside the station, when a direction of movement is actuated that is opposite to the direction of orientation of the station. The control assembly operates automatically according to the relative angular position of the station with respect to the carriage about the vertical axis and according to the command issued for the direction of movement.
