The transport vehicle with a chassis with a changing device and an interchangeable body which can be lowered onto the said device has lifting/lowering cylinder piston units which are operated in a lifting hydraulic circuit and lower and lift the interchangeable body accompanied by a hydraulic seating pressure, and locking elements on the changing device and on the interchangeable body, which elements lock the interchangeable body to the changing device by means of a locking travel when the interchangeable body is displaced, and at least one sliding-cylinder piston unit (60) which is operated in a sliding hydraulic circuit, and a driver device (80) and a control valve. The sliding-cylinder piston unit (60) which is attached to the chassis has a plate-shaped sliding rod head (82) on the sliding rod (81). Pressure plates (100.2) are spaced from one another by at least the thickness of the sliding rod head (82) in addition to the thickness of a folding plate (101) which is attached to the rear pressure plate (100.2) so as to be capable of folding upwards. As a result, a constrained sequence is brought about when matching engagement means to interchangeable body and interchangeable device during lowering. In addition, securing means which can be triggered by the locking travel are provided, which securing means secure the seated and locked interchangeable body against unintentional release. The driving device (80) and the sliding rod (81) can have an idle stroke at the start of the release movement, during which stroke the securing means can be released. <IMAGE>
