A collapsible loading and unloading ramp comprising two substantially parallel spaced longitudinal supports intended to be secured to a vehicle component, for instance a vehicle platform. Each of the longitudinal supports comprises a ramp portion which can be adjusted and locked in position with respect to the plane of the platform and an on-loading portion hingedly connected therewith. The ramp portion comprises three interconnected partial elements, the first partial element provided with a suspension means is hingedly, lockably secured at the second partial element and the second partial element together with the first partial element is secured to be laterally pivotable and fixable at the third partial element. Between both of the longitudinal supports, preferably however only at the region of the third partial element as well as at the on-loading portion, there are provided transverse supports arranged in spaced relationship from one another. The on-loading portion can be fixed in angled relationship to the ramp portion by means of a tension element, such as a chain which can be varied in length.
