摘要： A rail fastening device (10) comprises a clip 16 and a washer (17) for fastening to a rail support (12) by an upstanding bolt 14 having a nut (15), which can be tightened to lock the device (10) in position. The clip (16) and washer (17) comprise respective apertures (18), (19) for receiving the bolt (14). The washer (17) is adapted to rotate as the nut (15) is tightened until a formation on the washer (17) abuts an upstanding formation (24) on the rear of the clip (16) at point A, whereupon continued tightening of the nut (15) causes the washer (17) to pivot at point A around an offset axis, so as to bring the bolt (14) into contact with a front surface (18F) of the clip aperture (18). Further tightening of the nut (15) pivots the washer (17) to a point where any displacement force applied to the clip (16) by the rail is applied directly to the bolt (14) and not to the washer (17). In this manner, the risk of the washer failing, or bolt (14) bending is avoided.

摘要： The invention relates to a device for fastening trackside modules to a rail having a base and a head. The device includes two clamps that are clamped on the base of the rail with the use of a mechanism that extends under the base of the rail. At least one of the clamps is movable. A bracket is fastened to at least one of the clamps and a trackside module is fastened next to the head of the rail. A pair of brackets is fastened with the use of fasteners to surfaces of each of the clamps. The brackets extend transversely to the longitudinal axis of the rail and at least one upwardly extending section is fastened using second fasteners to at least one of the brackets outer side surfaces. At least one trackside module is fastened to an upper end region of at least one upwardly extending section.
