Patent ID: 10212927

Abstract:
A break-away apparatus for a boom arm (11) is positioned at a joint between a main boom portion (14) and a boom tip (12) to allow the boom tip to assume a neutral position and forward, rearward, and upward positions. First and second plates (30, 28) are disposed at the joint and a hinge assembly (22) is positioned between the first and second plates (30, 28). The hinge assembly (22) includes a first ball joint (38); a first hinge pin (34); and a second hinge pin (36). The first and second plates (30, 28) are in a first position when the boom tip (12) assumes the neutral position, and the first and second plates (30, 28) are movable with respect to each other about the first hinge axis (25a), the second hinge axis (25b), and a pivot point defined by the first ball joint (38). A first spring (50) assists a return of the first and second plates (30, 28) to the first position.
