A vehicle for loading and transporting heavyweight objects, in particular automotive vehicles, comprises an undercarriage, a loading bridge mounted directly on the undercarriage both longitudinally shiftable and tiltable about the rear portion thereof, and at least one power device engaging, preferably in the vicinity of, the front end of the loading bridge and on the other hand, preferably in the vicinity of, the rear portion of the vehicle undercarriage determining the mutual spacing thereof. The power device is alterable in its length. At least one pivot lever is guided at one end with a slide member in a bridge-stationary slide track and is mounted at its other end pivotally in a fulcrum underneath the effective line of the power device, behind the slide member as viewed in relationship to the direction of travel, at the vehicle undercarriage. The slide track at the front has an abutment which by an engagement with the slide member limits the lengthwise extension of the loading bridge.

A vehicle for loading and transporting heavyweight objects, in particular automotive vehicles, comprising: (a) an undercarriage having a front and a rear portion; (b) rear resilient suspension means supporting said undercarriage; (c) a loading bridge having a front and a rear end and mounted directly on said undercarriage for movement both longitudinally along said undercarriage and tiltably about said rear portion of said undercarriage; (d) at least one longitudinally extending power device extending between a forward position on said loading bridge and a rearward position on said undercarriage, relative to said forward position on said loading bridge; (e) at least one pivot lever, means slidably mounting one end of said pivot lever on said loading bridge adjacent the forward end thereof, and pivot means mounting the opposite end of said pivot lever on said undercarriage rearwardly of said slidably mounting means and below the effective line of said power device, said slidable mounting means being adapted to permit said one end of said pivot lever to slide along a predetermined path substantially parallel to said loading bridge and including abutment means at the forward end of said path; and (f) means actuated by tilting movement of said loading bridge for compressing said resilient suspension means; (g) whereby as said power device is retracted said loading bridge is caused to move rearwardly along said undercarriage until said one end of said pivot lever engages said abutment means of said slidably mounting means, said loading bridge is then caused to tilt with the forward end thereof driven upwardly by pivotal movement of said pivot lever and the rearward end thereof caused to move downwardly, and said resilient suspension means is compressed by said compressing means to lower said rear portion of said undercarriage.
