The invention relates to a load-handling vehicle ( 1 ) comprising a wheeled chassis ( 2 ) and, supported by said chassis ( 2 ),—an internal combustion engine ( 4 ),—a mechanism ( 5 ) for transmitting power from the internal combustion engine ( 4 ) to the wheels ( 3 ) of the chassis ( 2 ),—a bucket ( 7 ),—a system for moving said bucket ( 7 ),—a control unit ( 9 ),—an accelerator pedal ( 10 ),—a control member ( 11 ) which can be manually actuated by the driver of the vehicle,—a system ( 12 ) for detecting movements of the bucket ( 7 ). The power transmission mechanism ( 5 ) is configured so that a reduction in the rotational speed of the internal combustion engine ( 4 ) results in a reduction in the torque supplied to the wheels ( 3 ) of the chassis ( 2 ) and the vehicle ( 1 ) comprises at least one operating mode in which the control unit ( 9 ) is configured, in accordance with the data provided by the system ( 12 ) for detecting the movements of the bucket ( 7 ) and the control instructions of the system for moving the bucket ( 7 ), to reduce the rotational speed of the engine ( 4 ) to a value lower than the set value for speed control corresponding to the position of the accelerator pedal ( 10 ).

A working machine ( 1 ) includes a mobile chassis ( 2 ) that can move on a surface of the ground, a lifting arm ( 3 ) mounted on the chassis ( 2 ) to pivot about a horizontal axis ( 4 ) for a raising and lowering movement of the arm ( 3 ), and an accessory coupler ( 5 ) that can be secured to the free end of the arm ( 3 ) by a pivot link ( 6 ) with axis parallel to the axis ( 4 ) for pivoting the arm ( 3 ) with respect to the chassis ( 2 ). The coupler ( 5 ) has a plate ( 7 ) having a rear face ( 8 ) facing the arm ( 3 ) equipped with said pivot link ( 6 ) of the coupler ( 5 ) to the arm ( 3 ) and an opposite front face ( 9 ). The plate ( 7 ) is provided with a through-opening ( 10 ) and at least one part ( 61 ) of the pivot link ( 6 ) connecting the coupler ( 5 ) to the arm ( 3 ) is arranged facing the opening ( 10 ).

A handling machine ( 1 ) comprising: —a wheeled chassis ( 2 ), —a system ( 3 ) for handling a load and/or a person, —a control console ( 5 ) for controlling the members ( 4 ) for driving on the ground and for controlling the handling system ( 3 ) of the machine ( 1 ), —a control unit ( 6 ). The control console ( 5 ) has at least three selectively activatable use configurations. The first and second use configurations are use configurations in which the control console ( 5 ) is carried directly or indirectly by the chassis ( 2 ) of the machine ( 1 ). The third use configuration is a configuration in which the control console ( 5 ) is able to operate away from the chassis ( 2 ) and from the handling system ( 3 ) of the machine ( 1 ). The control unit ( 6 ) comprises a system ( 7 ) for determining the use configuration of the control console ( 5 ) and is configured to control the machine ( 1 ) according to the determined use configuration.

The invention concerns a working machine ( 1 ) comprising a mobile chassis ( 2 ) that can move on a surface of the ground, a lifting arm ( 3 ) mounted on the chassis ( 2 ) to pivot about a horizontal axis ( 4 ) for a raising and lowering movement of the arm ( 3 ), and an accessory coupler ( 5 ) that can be secured to the free end of the arm ( 3 ) by a pivot link ( 6 ) with axis parallel to the axis ( 4 ) for pivoting the arm ( 3 ) with respect to the chassis ( 2 ). The coupler ( 5 ) comprises a plate ( 7 ) having a rear face ( 8 ) facing the arm ( 3 ) equipped with said pivot link ( 6 ) of the coupler ( 5 ) to the arm ( 3 ) and an opposite front face ( 9 ). The plate ( 7 ) is provided with a through-opening ( 10 ) and at least one part ( 61 ) of the pivot link ( 6 ) connecting the coupler ( 5 ) to the arm ( 3 ) is arranged facing said opening ( 10 ).

The invention relates to a control method for controlling an actuating device in a handling machine, comprising: comparing ( 24 ) 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 ( 25 ) 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 ( 26 ) 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.

A handling machine with a telescopic arm, which comprises a hydraulic actuator system carried by a second section of the arm mounted so as to slide inside a first section, and a hydraulic control circuit which comprises a pipe system that extends at least partly inside the arm and which is connected to the hydraulic actuator system in order to supply said hydraulic actuator system. The pipe system comprises at least one flexible hydraulic pipe that extends inside the arm and which has a first portion fixedly mounted with respect to the first section; a second portion fixedly mounted with respect to the second section; and a U-shaped third portion which connects the first portion and the second portion to one another. The concave side of the U-shaped third portion is oriented towards the end of the first section that is opposite the end of the first section.

The invention relates to a control method for controlling an actuating device ( 8 ) in a handling machine ( 1 ) comprising a main movable body ( 2 ) and a handling arm ( 6 ) 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.

The invention relates to a load-handling vehicle ( 1 ) comprising a wheeled chassis ( 2 ) and, supported by said chassis ( 2 ),—an internal combustion engine ( 4 ),—a mechanism ( 5 ) for transmitting power from the internal combustion engine ( 4 ) to the wheels ( 3 ) of the chassis ( 2 ),—a bucket ( 7 ),—a system for moving said bucket ( 7 ),—a control unit ( 9 ),—an accelerator pedal ( 10 ),—a control member ( 11 ) which can be manually actuated by the driver of the vehicle,—a system ( 12 ) for detecting movements of the bucket ( 7 ). The power transmission mechanism ( 5 ) is configured so that a reduction in the rotational speed of the internal combustion engine ( 4 ) results in a reduction in the torque supplied to the wheels ( 3 ) of the chassis ( 2 ) and the vehicle ( 1 ) comprises at least one operating mode in which the control unit ( 9 ) is configured, in accordance with the data provided by the system ( 12 ) for detecting the movements of the bucket ( 7 ) and the control instructions of the system for moving the bucket ( 7 ), to reduce the rotational speed of the engine ( 4 ) to a value lower than the set value for speed control corresponding to the position of the accelerator pedal ( 10 ).
