<p>A forklift truck (10) comprising a truck body (20), a drive wheel (30), first forks (40), second forks or support arms (50) and a hydraulic system (100) which comprises a first, a second and a third hydraulic line (D2, D3, D6) for delivering hydraulic fluid to an hydraulic actuator (41) of the first forks (40), of the second forks (50) and of the drive wheel (30), respectively and a valve device (110) to which the hydraulic lines (D2, D3, D6) are connected, the valve device (110) being adapted to supply the highest one of the hydraulic fluid pressures (PU, PL) of the first and the second hydraulic lines (D2, D3) to the third hydraulic line (D6), thereby assuring a load-dependent drive wheel pressure during operation of the forklift truck, wherein the hydraulic system comprises at least one flow restriction (120) arranged to restrict hydraulic fluid flow between the hydraulic actuator of the first forks (40) or between the hydraulic actuator of the second forks (50), or of the support arms (50), and the valve device (110).</p> |
