A self-propelled land transporter is described which can be used optionally for guidance with an underfloor current and guide rail or as a non-rail-mounted hand-cart. For this purpose, on the one hand a current collector arm which can be pulled out of the underfloor current and guide rail and on the other hand an electric motor which can be connected to and disconnected from the front axle are attached to a live ring. The current collector arm is supported by support rollers in the vertical direction on the underfloor current and guide rail and guided laterally inside this guide rail by guide rollers. A current collector head can be rotated through 90<o> about a vertical axis in order to protect the sliders from damage during insertion into the guide rail and removal from the guide rail. Furthermore, the current collector arm bears a rail space container which is automatically pivoted downwards when travelling over a dirt collection shaft and at the same time releases an opening through which the foreign bodies removed from the guide rail fall into the collection shaft. When the transporter moves on, the rail space container is pivoted automatically back into the normal closed position by riding up on the floor of the underfloor current and guide rail. |
