Abstract:
A hydraulic tilting device to be fitted on a vehicle with a tiltable cab for the purpose of tilting the tiltable cab, which hydraulic tilting device comprises a hydraulic tilting unit having a double-acting hydraulic tilting cylinder for tilting the cab, and also having a reservoir for hydraulic fluid and having a pump for pumping the hydraulic fluid, the reservoir and the pump being arranged directly on the tilting cylinder, so that the tilting unit forms a single component, wherein the hydraulic tilting device furthermore comprises an additional hydraulic cylinder, which additional cylinder is connected to the hydraulic tilting unit via a system of fluid lines, said fluid lines comprising a cylinder part associated with the additional cylinder and a tilting unit part associated with the tilting unit, a disconnectable coupling being provided in each of said parts, the disconnectable coupling comprising a first coupling member, which is arranged on the tilting unit part of the connecting fluid lines and a second coupling member, which can be coupled to the first coupling member and is arranged on the cylinder part of the connecting fluid lines, the first coupling member and the second coupling member being uncoupled from one another, wherein the first and second coupling members are provided with shut-off means which shut off the associated part of the fluid lines, and wherein hydraulic fluid is present in the tilting unit and the tilting unit part of the fluid lines, and wherein hydraulic fluid is present in the additional cylinder and the cylinder part of the fluid lines.
