A passive switch for a railway track is disclosed. A railway car is moveable along the railway track in a facing direction. The passive switch includes a first track section and a second track section. The first track section includes a first main track, a first diverging track, and a first guard rail. The first guard rail is shaped to guide a first wheel of the railway car from the first main track onto the first diverging track as the first wheel travels in the facing direction within the passive switch. The second track section includes a second main track and a second diverging track. The second main track is shaped to guide a second wheel of the railway car from the second main track onto the second diverging track.

The present invention refers to an improvement developed on a pneumatic transport system for loads and/or passengers whose vehicles are not provided with on-board drive means, being guided on two exclusive tracks arranged in parallel. The vehicles travel over railway tracks laid over an elevated track supported by pillars. The center of the top of the superstructure of the elevated track has a longitudinal slot with seal by means of which the mast of the propulsion plate is allowed to move freely along the path of the vehicle. In the superstructure of the turnout beams there are mounted the mobile rails with their respective drive mechanisms and locking. A section isolation valve is positioned inside the propulsion duct of the turnout beams.

A turnout structure includes at least one turnout. The at least one turnout includes: a fixed beam set including a first side beam and a second side beam, and at least two movable beam sets disposed between the first side beam and the second side beam to define at least three switchable traveling pathways. Top surfaces of the at least two movable beam sets are configured to be a first traveling surfaces for traveling wheels of a rail vehicle to travel. Each of the at least two movable beam sets includes a rotating beam and a moving beam. A rotating center is located on a first end of the rotating beam, the rotating beam is configured to rotate around the rotating center, and the moving beam is connected to a second end of the rotating beam and configured to move along a path.

A turnout structure, which includes at least one turnout. The at least one turnout includes a fixed beam set. The fixed beam set includes a first side beam and a second side beam. The at least one turnout further includes a movable beam set. The movable beam set is disposed between the first side beam and the second side beam to define two switchable driving channels. A top surface of the movable beam set is configured as a first locomotion surface for locomotion wheels of a railway vehicle. The movable beam set includes a rotating beam and a moving beam. A first end of the rotating beam includes a rotating center. The rotating beam is configured to rotate around the rotating center, and the moving beam is connected to a second end of the rotating beam and configured to move along a path.

Rail system for an electrical pallet conveyor system, having a switch point which is arranged between a main track and a plurality of secondary tracks and which includes a plurality of moving rail sections. Depending on their position, the rail sections are able to connect the main track to the secondary tracks. The moving rail sections which are associated with one rail of the main track are in this case mounted on a first moving slide, and the moving rail sections which are associated with the second rail of the main track are mounted on a second moving slide which can move independently of the first slide. A dedicated drive which can be separately actuated by a control device is associated with each slide.

The disclosure relates to a lubrication-free piece having a friction surface that rubs against a second surface, the lubrication-free piece having at least one structure made from spheroidal graphite cast iron or steel, the external surface of the piece including at least one layer of lubricating thermoplastic polymers, wherein the lubrication-free piece includes a nickel/aluminium-based intermediary layer between the spheroidal graphite cast iron or steel structure and the layer of lubricating thermoplastic polymers.

Method for monitoring a track switch with a switch drive, wherein the switch drive includes a housing, a switch setting motor arranged in the housing and a switch rod extending out of the housing for coupling to a track switch. The method includes providing a piezoelectric sensor arranged on the housing and detecting measurement signals of the piezoelectric sensor during a switching operation of the switch drive. Periodic components of the measurement signal are at least partially filtered out in order to obtain signal components representative of a non-periodic change in the strain of the housing. The method also includes evaluating a temporal progression of the signal components representative of the non-periodic change in strain in order to identify deviations from a nominal state.
