    Abstract: A work vehicle is provided with a body and ground engaging means configured to allow motion of the body on ground, and braking means for locking ground engaging means, and an operative element carried by said body and configured to execute a specific working operation. The work vehicle further includes a first and a second joystick configured to respectively control the operation of ground engaging means and operative element based on movement of joystick and first and second input means configured respectively to control the activation/deactivation of parking brake functionality of the work vehicle and the activation/deactivation of hydraulic systems of work vehicle. Furthermore, the work vehicle includes a control system configured to receive second and first control signals derived from first and second input means respectively and each configured to assume a respective activation value and a respective deactivation value and inhibit the operation of the joystick linked to the operation of ground engaging means if both control signals are in activation state.

    Abstract: A parking brake system of a tipper vehicle having a tiltable tipper body is described. The system comprises a parking brake having a brake chamber which is pressurizable for releasing the parking brake. A valve device is in fluid communication with the brake chamber, the valve device comprising an exhaust port. The valve device has an activated state in which the brake chamber is in fluid communication with the exhaust port whereby air from the brake chamber is discharged, thereby applying the parking brake, and an inactivated state in which said fluid communication is disconnected. Upon receipt of a tipping signal, a neutral gear signal and a low speed signal, and upon detecting that the parking brake is still in the released state, the valve device is changed from the inactivated state to the activated state in order to exhaust air from the brake chamber, causing the parking brake to become changed to the applied state.
