Claims38
A nail punching machine for driving in rail spikes of a rail track, the nail punching machine comprising:
- at least one handle for holding the nail punching machine;
- an axial driving mechanism configured to work in an exclusively linear manner in an axial direction of the nail punching machine, the axial driving mechanism comprising a striking mechanism for driving a rail spike into a tie;
- a tool configured as a hammer for driving in the rail spike;
- an electric drive motor for driving the axial driving mechanism, wherein a rotation of the electric drive motor causes a linear movement of the striking mechanism along the axial direction and the striking mechanism is configured to strike the tool, wherein the tool is configured to be displaced downwards and upwards in a linear manner to drive in the rail spike;
- and
- an accumulator for supplying the electric drive motor with electric power.
