Apparatus and method for applying and removing transversely applied elastic rail clips

摘要

A machine is capable of automatically applying and removing transversely applied rail clips such as the so-called Safelok-type clip. The machine preferably includes a workhead on which is disposed one or more applicator/remover mechanisms, each of which is capable of automatically applying and/or removing a clip. Each clip applicator/remover mechanism preferably includes a workarm which is pivotable transversely towards and away from the longitudinal centerline of the rail, a clip applicator tool mounted on the workarm, and a clip retractor tool mounted on the workarm. The resulting mechanism is capable of both applying and removing clips rapidly and efficiently while accommodating variations in position and orientation of the rail and/or the clips.
