Dual power swivel system

A power swivel system for an articulated machine having a front chassis, a cabin, and a boom apparatus, comprising:

• a core having a rotational axis extending from a first end to a second end, the core including an electrical conduit running from the first end to the second end, and a port disposed as a vertical channel along the rotational axis of the core;
• a first portion disposed about and coupled to the core and configured to rotate with the cabin of the articulated machine, the first portion including a first manifold and a second manifold coupling the first portion to the cabin and providing hydraulic power to the first portion and a first slip ring assembly for providing electrical power to the cabin, the first slip ring assembly including
• a first slip ring input configured to receive an electrical wire from the cabin,
• a first slip ring lug,
• a first conductive ring in electrical communication with the first slip ring lug,
• a first brush in electrical communication with the first conductive ring,
• a first slip ring in electrical communication with the first brush and disposed inward toward the rotational axis relative to the first slip ring assembly, and
• a rod in electrical communication with the first slip ring;
• a second portion rotatably disposed about the core and configured to rotate with the boom apparatus of the articulated machine, the second portion including a support manifold for coupling the second portion to the boom apparatus, a first jug for providing hydraulic power to the boom apparatus, a second slip ring assembly for providing electrical power to the boom apparatus and having
• a second slip ring input,
• a second slip ring lug,
• a second conductive ring in electrical communication with the second slip ring lug,
• a second brush in electrical communication with the second conductive ring, and
• a second slip ring in electrical communication with the second brush and disposed inward toward the rotational axis relative to the first slip ring assembly;
• and
• a third portion disposed about the core and stationary within and coupled to the front chassis, the third portion for providing hydraulic power via a second jug and a third jug and electrical power to the front chassis,
• wherein the first portion and the second portion rotate independently of one another and the third portion to allow the cabin and the boom apparatus to rotate independently of one another and the front chassis.
