Abstract:
An automatic gate arm damage prevention system includes a lift arm that is coupled to a lifting apparatus. The lift arm has an outer end, an upper side, a lower side, a first lateral side and a second lateral side. A channel extends into the outer end and the upper side so that the channel is bounded by the first and second lateral sides and the lower side. An elongated member has a first end and a second end. The first end is positioned in the channel. A pivot pin extends through the channel and through the elongated member and the lift arm to pivotally couple the elongated member to the lift arm. The second end is pivotable upwardly with respect to the lift arm.
