1. A rail conveyor element which is adapted to be displaced on a rail system with intersecting rails comprising:
a base,
a wheel-bearing cassette having the base mounted thereon, and which, in a transport position of the rail conveyor element supports the base,
at least one wheel in the wheel-bearing cassette and accommodated to rest on a said rail and
a pressure ram with actuator which extends downward on or below said wheel-bearing cassette and is adapted to be moved by an actuator between a raised unloaded position which coincides with the transport position of the rail conveyor element and a lowered loaded position for unloading the wheel-bearing cassette relative to a said rail,
wherein the wheel-bearing cassette is mounted to be rotatable around a vertical axis relative to the base,
wherein the pressure ram is designed, in its loaded position, to lift the wheel-bearing cassette together with the base off the rails.
