Ramp for loading and unloading of vans and similar vehicles

The apparatus comprises at least one ramp (7) which can be arranged in an inclined operative position and a support structure (9) for the ramp (7) which can be fixed to a van and enables the ramp (7) to be displaced and selectively arranged in three different configurations: the inclined operative position, a first rest position, in which the ramp (7) is perpendicular to the load plane (6) of the van and is parallel to the edge of the load plane (6), and a second rest position in which the ramp (7) is located externally of the load plane (6).
