A rail fastening device (100) comprises a lower plate (11) and an upper plate (12) provided with a pair of clips (13) for engaging the rail 16, the upper plate (12) being fastened to the lower plate (11) by a pair of fastening bolts (19) which extend through respective apertures (20) in the upper plate (12), the fastening bolts (19) being slidably mounted to the lower plate (11) for movement in a direction which, in use, extends transverse the rail (16). A jacking bolt (31) is arranged to lift the upper plate away from the lower plate as the bolt (31) is tightened and vice-versa. An alignment bolt extends 33 laterally between the upper and lower plates (11), (12) and is rotatable to displace the upper plate (12) laterally relative to the lower plate (11). A levelling bolt (102) threadably engaged with the lower plate is arranged to lift the lower plate (11) away from the surface on which the device (100) is seated as the bolt (102) is tightened and vice-versa.
A rail fastening device comprising a lower plate, an upper plate and a pair of clips for engaging the rail to be fastened, wherein the upper plate is fastened to the lower plate by a pair of fastening bolts which extend through respective apertures in the upper plate, the fastening bolts being slidably mounted to the lower plate for movement in a direction which, in use, extends transverse the rail, wherein the clips are slidably mounted to the upper plate by respective said fastening bolts, and a jacking bolt is threadably engaged with the upper plate and has a lower end which abuts the upper surface of the lower plate, the jacking bolt being arranged to lift the upper plate away from the lower plate as the bolt is tightened and vice-versa.
A rail fastening device comprising a lower plate and an upper plate fastenable to the lower plate, wherein a jacking bolt threadably engaged with the upper plate has a lower end which abuts the upper surface of the lower plate, the jacking bolt being arranged to lift the upper plate away from the lower plate as the bolt is tightened and vice-versa.
A rail fastening device comprising a lower plate and an upper plate fastenable to the lower plate, wherein an alignment bolt extends laterally between the upper and lower plates substantially in the plane thereof, the bolt being rotatable to provide a force between the upper and lower plates which acts to displace the upper plate laterally relative to the lower plate.
A rail fastening device comprising a lower plate and an upper plate fastenable to the lower plate, wherein a levelling bolt threadably engaged with the lower plate has a lower end arranged to abut a surface on which the device is seated, the levelling bolt being arranged to lift the lower plate away from a surface on which the device is seated as the bolt is tightened and vice-versa.
