The lifting device has a lifting pump mounted on a console which is placed on a support that is, in turn, mounted on the axle extending between both wheels. A rod is mounted on the lifting pump, and the lifting pump has a piston rod whose head projects upwardly out of the housing of the lifting pump. A roller is mounted at the rear end of each bearer, and the bearers are connected to one another at the front end via a crossbar. A holding frame having a socket is provided on the front end of the bearers and is mounted in an articulated manner on the head of the piston rod. A two-armed linkage is mounted on both sides of the console. The front arms of this linkage are connected to the console and the rear rod of the linkage is connected to the allocated roller each of which being connected in a manner that permits them to pivot.
