The invention relates to a machine () for handling loads (), comprising: —a wheeled chassis (), —a drive system () for moving the wheeled chassis (), —a load handling system () carried by the chassis (), —a control unit (), a device () for controlling the load handling system () that can be manually actuated by an operator, the control unit () being configured to receive control signals from said control device (), a member () for activating the manually actuatable control device (). The handling machine () comprises a sensor () of a parameter representative of a movement of the machine (), and the control unit () is configured to allow the control of the handling system () with the control device () as a function of at least the parameter representative of a movement of the machine ().

Load handling machine and method for controlling a load handling machine

The invention relates to a handling machine () comprising: a tilt sensor () configured to produce a signal relating to a tilting moment applied to the main body about a tilting axis; displacement sensors () configured to produce a signal relating to movements of the handling arm relative to the main body; and a control unit () configured to: prevent or stop the movement of the handling arm if the signal representative of the tilting moment is greater than an effective threshold; assign a lowering threshold value to the effective threshold in response to a handling arm lowering movement being determined; and assign an extension threshold value to the effective threshold in response to a handling arm extension movement being determined.

Control of a handling machine

The invention relates to a control method for controlling an actuating device in a handling machine, comprising: comparing () a magnitude representative of the movement speed executed or to be executed in response to a movement request signal to a threshold representative of a maximum authorised speed and controlling an actuating device according to the result of said comparison, so as to: execute or sustain () the movement of a handling arm as long as the magnitude representative of 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 representative of the speed of movement executed or to be executed is greater than said threshold.

The invention relates to a control method for controlling an actuating device () in a handling machine () comprising a main movable body () and a handling arm () intended to receive a load that is to be moved, the actuating device being configured to perform a movement of the handling arm in relation to the main body, the method comprising: measuring a parameter indicative of a tilting force applied to the main body in relation to a tilting axis, and stopping or hindering a movement of the handling arm performed or requested when a stopping condition is met, the stopping condition being dependent on the parameter indicative of the measured tilting force, and, in which, when a reinforced operating mode is selected, the stopping condition is also dependent on a parameter representative of the speed of the movement of the handling arm.
