1. A handling machine comprising:
a main body;
a handling arm intended to receive a load that must be moved;
an actuating device configured to execute a movement of the handling arm relative to the main body;
a control component operable by a user in order to generate a movement request signal intended to direct the actuating device to execute or to stop a movement of the handling arm by the actuating device in response to the movement request signal, the movement request signal having an attribute representing a speed of the movement to be executed, the control component being operable by the user in order to adjust the attribute of the movement request signal from a plurality of attribute values respectively representing a stop state and a plurality of speed values;
a control unit configured to compare a magnitude representing the speed of the movement executed or to be executed in response to the movement request signal to a threshold representing a maximum authorized speed and to control the actuating device as a function of the result of said comparison, so as to:
execute or sustain the movement of the handling arm as long as the magnitude representing the speed of the movement executed or to be executed is less than said threshold; and
prevent or stop the movement of the handling arm as soon as the magnitude representing the speed of the movement executed or to be executed is greater than said threshold.
