The invention relates to a handling machine (1) comprising a main body (2), a handling arm (6) mounted on the main body (2) and movable relative to the main body (2) so as to rotate between a raised position and a lowered position, an actuating device (8) configured to raise and lower the handling arm (6), a tilting detector (11) configured to produce a signal, referred to as instability signal relating to a tilting moment applied to the main body (2) about a tilting axis of the handling machine, and a control unit (10) configured to control the actuating device (8). The control unit (10) is configured to determine the speed of variation of the value of the instability signal, and to generate a signal for stopping or slowing a movement of the handling arm (6), as a function of the speed of variation of the instability value and of a threshold value of the speed of variation of the instability. The invention further relates to a corresponding control method.
A handling machine (1) including:
The handling machine (1) as claimed in any one of the preceding claims characterized in that said handling arm (6) is a telescopic arm deployable and retractable in a longitudinal direction of said handling arm and the actuating device (8) is also configured to deploy and to retract said handling arm (6).
The handling machine (1) as claimed in any one of the preceding claims characterized in that said tipping detector (11) includes at least one extensometer (61) preferably arranged on an axle (60), for example a rear axle, of the handline machine,
The handling machine (1) as claimed in any one of the preceding claims characterized in that the handling machine (1) includes a warning system including warning elements such as indicator lamps switching on of which is a function of the rate of variation of the instability signal.
The handling machine (1) as claimed in any one of the preceding claims characterized in that said signal to halt or to slow movement of the handling arm (6) is a signal to halt or to slow a movement of lowering or extending the handling arm (6).
A method of controlling a handling machine (1) including a main body (2), a handling arm (6) mounted on said main body (2) and rotatable relative to the main body (2) between a raised position and a lowered position, and a tipping detector (11) configured to produce a signal called the instability signal relating to a tipping moment applied to the main body (2) about a tipping axis of said handling machine,
