A profiled bearing for a rail and a rail system are disclosed. The profiled bearing has a profiled base with a first lateral wall, a second lateral wall, and a base which connects a first end of the first lateral wall to a first end of the second lateral wall, and the profiled bearing also has a profiled clamping section. The base and the lateral walls form a receiving pocket for receiving the rail. In a functional position, the profiled clamping section is clamped in a gap between the rail inserted into a bearing bed of the base and the second lateral wall. A clamping finger which extends in the direction of the second lateral wall is molded in the region of a second end of the first lateral wall, the end being arranged at a distance from the base, wherein the rail can be pressed into the bearing bed by means of the clamping finger, and the profiled clamping section has a base web with two clamping limbs which extend from one face of the base web and which can be pressed into the gap between the rail inserted into the bearing bed and the second lateral wall. The clamping limbs of the profiled clamping section extend in the direction of the bearing bed in the functional position in which the clamping limbs are inserted into the gap, and a first clamping limb lies against the rail at least in some regions and a part of a second clamping limb is pressed into an undercut formed on the second lateral wall.

An elevated guideway performing the function of supporting, guiding and propelling pneumatic transport vehicles for passengers and loads. The two-part elevated guideway is formed by two components, each corresponding to one side of the cross section, divided by a vertical axis passing through the center of the slot. Components are not symmetrical, the left hand component having a wider top table. Components are joined through a niche already present at the lower slabs which is filled with a structural resin. Niche for joining the two-part elevated guideway has a central type female-female fitting. The elevated guideway includes guideway guards, two additions for installing the propulsion duct slot seal, tubes for the electric power supply and telecommunication and control cables, the protective railing for protection in the side emergency gangway, the unit for securing the rail via the web thereof, rails and the third and fourth electric power supply rails of the vehicle. The two-part elevated guideway may have, combined on the same beam of the propulsion duct, a secondary propulsion duct, thereby forming a single, non-separable structure.

The present disclosure provides a sea tunnel, and relates to the technical field of sea-crossing bridge tunnels. The sea tunnel comprises a body; and the body has a hollow cavity extending from one end to the other end, the cavity is divided into mutually independent first cavity and second cavity by a passage pavement, the first cavity is mainly used for passing and is wholly or partly protruded out of the sea level, the second cavity is immersed in the seawater, water holes are formed in the second cavity, and the second cavity is communicated with the seawater through the water holes. When the seawater impacts one side of the body, the second cavity is immersed in the seawater, and the seawater flows into the second cavity, so the body is not easy to be flushed over by the seawater.

A longitudinally curved support rail (56) for supporting and moving a drive chain assembly (52) at the base of a spiral conveyor belt (34) to drive the bottom tier (30) of the spiral conveyor belt while being supported by the support rail. The support rail including an upright web section (80) and a support flange (78) cantilevered outwardly from the web section to provide a platform or shelf to support a chain drive assembly (52), thereon during travel of the chain drive assembly along the support rail.

A segmented track for a Maglev vehicle includes a structural support portion and a Maglev portion fastened to the structural support portion. Each segment of the structural support portion is formed by fusing together three cast metal components. Neighboring ones of the structural support segments are joined together end-to-end by fused metal, and neighboring ones of the reaction rail segments are joined together end-to-end by fused metal. The positioning and joining of the successive segments is done in the field using on site jigs and machines.

Switch (1) of a transport system for a movable transport element (T), where the switch (1) comprises a main track (3) and a secondary track (4) branching off, where the movable transport element (T) can be guided from a transition region (2), in which the secondary track (4) branches off from the main track (3), optionally along the main track (3) or transferred into the secondary track (4), where one or more linear motor sections (5a, 5b, 5c, 5d) are respectively provided at the main track (3) and at the secondary track (4) for moving the movable transport element (T), where a switching force can be generated by way of the one or more linear motor sections (5a, 5b, 5c, 5d) with which the movable transport element (T) can be guided along the main track (3) or transferred into the secondary track (4), characterized in that devices for creasing the switching force are provided in the transition region (2). Transport system comprising such a switch and transport element for such a transport system.
