A chord protector employs a resilient covering affixed to an appropriate crane element, extension, lattice structure or headache ball, to protect a chord from damage during a collision with a headache ball or other weighty object. The chord protector can be constructed of a variety of materials. In one embodiment, the chord protector is constructed of high-impact plastic, and lined with an elastomeric or rubber material which in turn is fastened to a chord of the lattice section using a disengagable hook and loop fastener. Another embodiment includes an elastomeric covering on the headache ball.
