A rail fastening device comprises a clip (10) having a base (11) and a nose (12) for engaging a rail flange (F). The base (11) comprises circular aperture (14) in which a circular cam (13) is rotatably mounted, the cam (13) being provided with an eccentric aperture (24) for receiving a ground anchor (25), the cam aperture (24) being radially offset from the rotational centre of the cam (13) to define a cam lobe (15). The cam (13) may comprise a ramped circumferential shoulder (18) to engage a complementary shoulder (21) inside the base aperture (14) such that any rotation of the cam (13) under the applied load of the rail causes the cam (13) to move axially of the base aperture (14) thereby tightening the engagement of the anchor (25) on the cam (13) and preventing movement of the clip (10). The degree of rotation of the cam (13) may be limited so that it can only turn in the tightening direction under load.

A device for transferring an infrastructure component pre-positioned on a ground, particularly a track support plate, into a target arrangement, comprises a connecting means for fastening the device to a mating connecting means of the infrastructure component, a ground contact means for support on the ground, an actuating device for absorbing a first rotational movement about a first axis of rotation, and a transmission device for converting the first rotational movement into a first transferring movement of the ground contact means relative to the infrastructure component with a translatory movement component orientated perpendicular to a first axis of rotation. A combination and a system comprising at least one such device. A method for transferring an infrastructure component.

A rail system for a conveyor vehicle capable of traveling along the rail system for storage of piece goods into a storage rack or retrieval of piece goods from a storage rack includes a first running rail, a second running rail and a connecting device, which includes a positive locking connection between the ends, directed toward one another, of the first running rail and second running rail. At its end, the first running rail forms a first interlocking element and a first surface portion. At its end, the second running rail forms a second interlocking element and a second surface portion. Therein the first interlocking element and second interlocking element engage in one another in complementary manner and the ends of the first running rail and second running rail abut at the surface portions in a butt-jointed manner. Furthermore, a warehouse system has such a rail system.

A system for securing a railway apparatus includes a support platform and a mechanism for securing the railway apparatus to the support platform, capable of switching from an unlocked state to a locked state. The securing mechanism has a guide rail, a trolley guided by the guide rail along a path which, when the support platform is in the loading position, is parallel to a reference plane, a device for immobilizing the trolley relative to the guide rail, an attachment member for attaching the railway apparatus secured to the trolley; and locking members for locking the guide rail relative to the support platform, which switch from an unlocked position to a locked position when the securing mechanism switches from the unlocked state to the locked state in the loading position of the platform, by urging the guide rail downwards relative to the support platform.

A rail fastening system for fastening a rail on a subsurface, preferably a ballastless track, comprises at least one retaining element for mounting the rail on the subsurface. The retaining element has an angle guide plate that, in the assembled state, is configured to divert transverse forces from the rail into the subsurface and a shoulder part that, in the assembled state, is configured to butt together with the angle guide plate and to lie in a recess of the subsurface in a positive-locking manner.

The present invention provides an adaptive vibration isolator. The adaptive vibration isolator includes a hydraulic system, a first elastic member, a second elastic member, an upper top plate, and a vibration energy consumption device. The hydraulic system comprises a hydraulic cylinder, a piston and a piston rod, a first though hole is formed on the piston, and the first hydraulic chamber is communicated with the second hydraulic chamber via the first through hole. An upper top plate passes through the piston rod and the piston from the transmission portion and is connected to the vibration energy consumption device to drive the vibration energy consumption device to move relative to the piston and adjust the effective aperture of the first through hole.
