Abstract
A nipper-clipper assembly for lifting railroad ties and installing clip assembly springs to couple rails to a tie. The ties are disposed below the rails and extending in a lateral direction relative to the longitudinal rails. The nipper-clipper assembly includes a main beam assembly, a right side clipping assembly, a left side rail clipping assembly, a right side nipper assembly having a pad assembly, and a left side nipper assembly having a pad assembly. The nipper assemblies and the clipper assemblies are coupled to the main beam assembly. The right side pad assembly and the side pad assembly are structured to act upon the tie by contacting the lateral ends of the tie.
