WORKHEAD FOR REMOVING A RAILWAY TRACK FASTENER
The present invention relates broadly to an apparatus 10 for removing one of a plurality of railway track fasteners such as 12a to 12h used to secure a pair of laterally spaced railway tracks 14a and 14b to underlying sleepers such as 16a to 16f. The track fasteners such as 12a are each in the form of an e-clip or PR-clip fastener of a known configuration. The apparatus 10 comprises a support frame assembly 20 adapted to locate on the railway tracks 14a/b, a drive assembly 22 mounted to the support frame assembly 20, and a workhead 24 associated with the support frame assembly 20 for removal of the track fastener such as 12a. The workhead 24 comprises a percussion hammer 32 and an associated hammer moil 34 arranged for removal of the fastener 12a. The hammer moil 34 includes a moil mount 38 connected at a predetermined angular offset to a moil head 40. The hammer moil 34 is rotatable relative to the percussion hammer 32 during removal of the track fastener 12a whereby alignment between the moil head 40 and the fastener 12a is maintained.
