An industrial vehicle, such as a semi-trailer truck or a tractor, or a dump truck, or a military vehicle, or a heavy-duty construction vehicle. comprising a pneumatic system, a first mechanical device and a second mechanical device, the industrial vehicle comprises a steering column, a steering wheel, at least a first articulation and a second articulation, wherein the first articulation allows a pivoting movement (F2, F2') of the steering column, relative to a fixed frame of the vehicle, around a respective first rotation axis (X36, X37), wherein the second articulation allows a tilting movement of the steering wheel relative to the steering column, around a second rotation axis, the pneumatic system including: - a first pneumatic actuator for commanding the first mechanical device, - a second pneumatic actuator for commanding the second mechanical device, - a pneumatic control valve switchable between several states to command of the first and second actuators (6, 8); wherein the first mechanical device is a locking mechanism of either one of the first articulation or the second articulation and the second mechanical device is a locking mechanism of the other articulation, wherein the control valve comprises an actuation portion, movable in translation between: - a resting position, corresponding to a first state of the control valve, - a first pushed position, corresponding to a second state of the control valve, and - a second pushed position, corresponding to a third state of the control valve, and wherein the first pushed position corresponds to an intermediary position between the resting position and the second pushed position. comprising a pneumatic system, a first mechanical device and a second mechanical device, the industrial vehicle comprises a steering column, a steering wheel, at least a first articulation and a second articulation, wherein the first articulation allows a pivoting movement (F2, F2') of the steering column, relative to a fixed frame of the vehicle, around a respective first rotation axis (X36, X37), wherein the second articulation allows a tilting movement of the steering wheel relative to the steering column, around a second rotation axis, the pneumatic system including: - a first pneumatic actuator for commanding the first mechanical device, - a second pneumatic actuator for commanding the second mechanical device, - a pneumatic control valve switchable between several states to command of the first and second actuators (6, 8); - a first pneumatic actuator for commanding the first mechanical device, - a second pneumatic actuator for commanding the second mechanical device, - a pneumatic control valve switchable between several states to command of the first and second actuators (6, 8); wherein the first mechanical device is a locking mechanism of either one of the first articulation or the second articulation and the second mechanical device is a locking mechanism of the other articulation, wherein the control valve comprises an actuation portion, movable in translation between: - a resting position, corresponding to a first state of the control valve, - a first pushed position, corresponding to a second state of the control valve, and - a second pushed position, corresponding to a third state of the control valve, - a resting position, corresponding to a first state of the control valve, - a first pushed position, corresponding to a second state of the control valve, and - a second pushed position, corresponding to a third state of the control valve, and wherein the first pushed position corresponds to an intermediary position between the resting position and the second pushed position.
