Abstract
A high speed trolley harp assembly includes a rotatable portion at the upper end of a trolley pole with a shoe assembly held on a support structure which is pivotally connected to a lower body at the upper end of the pole. Elastomeric, resilient support cushions are held in the lower body protruding therefrom and contact the support structure to provide a cushioning effect to absorb shock, vibration and noise occurring at high speeds when the shoe assembly rides along an overhead conductor.
