Patent ID: 10414633

Abstract:
A utility system may include at least one moveable arm, and at least one grappling assembly connected to the moveable arm. The grappling assembly includes an upper claw, a lower claw, and fasteners to pivotally secure the lower claw to the upper claw. The upper claw includes lower grasping surfaces and coupling openings. The lower claw includes upper grasping surfaces and mating openings. Each mating opening is axially aligned with one of the coupling openings. The upper and lower claws rotate about the fasteners at first pivot axes when the fasteners are retained within first coupling openings of the upper claw and within the mating openings of the lower claw. The upper and lower claw rotate about the fasteners at different, second pivot axes when the fasteners are retained within second coupling openings of the upper claw and within the mating openings of the lower claw.
