In the current state of the art, diagnostic car lifts fitted either with drive-on runways or support cradles that grasp under the body are used in garage workshops. Those car lifts fitted with drive-on runways require much floor space, are difficult to drive on, and cover a large part of the underfloor of the vehicle. If the diagnostic car lifts are built to grasp under the body, they require an excessively long set-up time which the operator has to spend in an uncomfortable position. The invention consists of a support cradle that is connected to one or two jacks of a one-jack or two-jack car lift that can retract into the floor. Instead of drive-on runways, the support cradle has very shallow, sprung support frames (3) that grasp under the wheels; it can be adjusted to the vehicle's wheel base by a foot control, and only covers a small part of the vehicle's bottom. Another significant advantage is that the support cradle only presents a small obstacle for a car that is to be pushed. <IMAGE>
