Workhead for removing a railway track fastener
An apparatus is used to remove one of a plurality of railway track fasteners that secures a pair of laterally spaced railway tracks to underlying sleepers. The track fasteners are each in the form of a known e-clip or PR-clip fastener. The apparatus includes a support frame assembly adapted to locate on the railway tracks, a drive assembly mounted to the support frame assembly, and a workhead associated with the support frame assembly for removal of the track fastener. The workhead includes a percussion hammer and an associated hammer moil arranged for removal of the fastener. The hammer moil includes a moil mount connected at a predetermined angular offset to a moil head. The hammer moil is rotatable relative to the percussion hammer during removal of the track fastener whereby alignment between the moil head and the fastener is maintained.
