A central pivot pendant arm system is provided for running cabling internally within a shoulder casting through a shaft that provides an axis of rotation and cabling access through a side opening in the shaft. The shoulder casting is pivotable about the axis of rotation and partially encloses a portion of the shaft. The shoulder casting has a protrusion for attachment of a pendant arm and facilitates cabling passage inside the shoulder casting, between the shaft side opening and the pendant arm interior.
