A bat wing for a shuttle car includes a top plate, a lower plate and at least one shieve wheel positioned between the top plate and the lower plate for spacing the top plate a predetermined distance from the lower plate. The lower plate includes at least a first edge, second edge and third edge substantially contiguous to each other and forming the lower plate having a predetermined area. The first and second edges of the lower plate forming a lower edge spaced a predetermined distance from the at least one shieve wheel. The top plate includes at least a first edge, second edge and third edge substantially contiguous to each other and forming the top plate having a predetermined area being greater than the predetermined area of the lower plate. The first and second edges of the top plate forming a top edge spaced a predetermined distance from the at least one shieve wheel and extending outwardly therefrom a distance greater than the predetermined distance of the lower edge from the at least one shieve wheel. An insulation member is disposed on the top and lower plates for reducing cable arcing and abrasive damage as a cable passes between the top and lower plates.
