A dockboard assembly is provided having a releasable holding means for restraining the upward pivoting of a ramp means, the latter being urged to pivot upwardly by a biasing means. The holding means is adapted to be adjusted to a release position either by a manually actuated first release means or by a second release means which is actuated automatically only upon the ramp means having assumed a predetermined position of pivotal adjustment and an external upwardly pivoting force exceeding a predetermined magnitude being exerted on the ramp means.
