Abstract (en)
[origin: FR2863634A1] The vehicle (1) has a hydraulic jack (7) moving arms (6) of a work equipment (5) with respect to a frame (2). A hydraulic circuit supplies the jack based on control orders issued from a hydraulic manipulator. The jack is freely moved when the manipulator is in a floating control position and the vehicle is in a loading mode. A pressure reducing valve inactivates the floating control position, when the vehicle is in a lifting mode.
