Abstract: A rotary dangle head having continuous rotation includes a rotator, a continuous rotary hydraulic union and a dangle head. The rotator includes a support base, a slewing ring, a mounting plate and a ring rotator. The slewing ring includes an outer bearing ring and an inner bearing ring. The dangle head includes a retention bracket and a processing head. The processing head is pivotally retained by the retention bracket. The outer bearing ring is attached to a bottom of the support base. The inner bearing ring is attached to a top of the mounting plate. The ring rotator drives the outer bearing ring. The retention plate is attached to a bottom of the mounting plate. The continuous rotary hydraulic union is connected to hydraulically driven components mounted to the processing head.
