Abstract: The invention related to a process for suspending on a vehicle frame a driving cab which has two-point suspension. Assembly involves the cab being lowered towards the frame by means of a lifting device so that a contact device fitted to the cab is caused to rest on the portions of a supporting device which protrude on either side of a supporting unit mounted on the frame. This means that the cab lies in a stable manner against the frame and that the fastening apertures of the contact device and of the supporting device are placed centrally to one another. The lifting device can therefore be released and the contact device be secured to the fastening device, thereby fixing the contact device relative to the supporting device but leaving the supporting device freely rotatable in the supporting unit.
