Abstract:
A break-away apparatus for a boom arm is positioned at a joint between the main boom portion and the boom tip. The apparatus allows the boom tip to assume a neutral position and to pivot forward and rearward. The apparatus includes a first plate disposed at the joint, a second plate disposed at the joint, and a hinge assembly positioned between the first plate and the second plate. The hinge assembly includes a hinge pin having a longitudinal axis. The first and second plates are in a first position with respect to each other when the boom tip assumes the neutral position. The first and second plates are movable with respect to each other about the longitudinal axis. A torsion spring is configured to return the first and second plates to the first position after the first and second plates move from the first position.
