The self-propelled working machine (1) comprises: moving means (2) configured for allowing movement of the machine on a bearing plane (3); propulsion means (4) operatively associated to the moving means and configured to cause and maintain the movement of the working machine on the bearing plane; a frame (5) supporting the moving means and the propulsion means, an operating member (6) and relative actuating means, a maneuver cab (7) arranged directly or indirectly on the frame (5) and comprising at least an access door (8), the cab (7) and the frame (5) defining an encumbering volume of the machine.

The machine 1 comprises a step board (11) arranged at the access door (8) of the maneuver cab (7) and coupling means (13, 17) operatively associated to the maneuver cab (7) and/ or to the frame (5) of the working machine for supporting said step board (11), the coupling means being configured for allowing an actuation movement of the step board (11) between a retracted position in which said step board (11) remains substantially inside the encumbering volume, and an extracted position in which it protrudes, thereby defining a supporting surface, walkable by the operator, able to facilitate entering the maneuver cab.

A passenger rail vehicle includes at least one linearly movable step platform which is disposed in a boarding region of the rail vehicle and is used to bridge a gap in the horizontal direction between the boarding region of the rail vehicle and a station platform. The step platform includes a front section which forms part of a step surface of the step platform. The front section is mounted about a horizontal axis so that it can pivot on the step platform to form a ramp between a remaining step surface of the step platform and the station platform.

A vehicle, in particular a passenger rail vehicle, has at least one door. In the area of the door, the vehicle has a sealing web which is arranged on a floor of the vehicle and can be moved at least between a sealing state and an open state, such that, in the sealing state, the sealing web projects out of the floor and forms a sealing surface for sealing off the closed door with respect to the interior of the vehicle, and that, in the open state, the sealing web is recessed in the floor.

A movable footboard for a door of a rail vehicle comprises a footboard extendable below a tread strip at least substantially transversely to the direction of travel. To minimize the level difference between the footboard and the tread strip a pivot shaft extends at least substantially parallel to the direction of travel on at least one longitudinal bar of the footboard at the end region of the footboard away from the vehicle, about which pivot shaft at least two pivoting bars are pivotably supported, which pivoting bars each bear a transverse profile element, each of the pivoting bars being rigidly connected to the transverse profile element associated with the pivot bar, while the other transverse profile elements lie freely on said pivot bar, and a lifting mechanism is fastened to the vehicle and lifts the transverse profile element located directly in front of the tread strip.

The present disclosure relates to a safe foothold apparatus for a platform, wherein a foothold plate protrudes from and is retracted into the platform by moving along a curved rotational route so that the foothold plate is re-retracted into the platform safely due to the operation structure even when a collision occurs between a train and the foothold plate in a protrusion state. Therefore, the present invention can prevent the foothold plate and the train from being damaged, thereby establishing safer boarding/alighting environment and stably maintaining the operational state of the foothold plate by using a frictional contact module even in an emergency situation. Accordingly, the present invention can improve safety through a simple structure, facilitate the manufacturing and establishment work by simplifying a structure of a manual operation module, reduce the size of a whole apparatus, and far enhance the operational stability.

A step device for a rail vehicle includes a step platform, a housing from which the step platform is extendable and retractable again, and a regulating unit for controlling the extension and retraction movement of the step platform. The step platform includes a plurality of step contact segments which, when subjected to pressure, generate signals which are transmitted to the regulating unit. The step contact segments are disposed at predefined distances greater than zero with respect to one another on the step platform in such a manner that an object of predefined minimum contact area with the step platform subjects at least two directly adjacent step contact segments to pressure, and the regulating unit is configured in such a manner that a relevant object is recognized only when signals of two directly adjacent step contact segments are transmitted.
