    Abstract: A ridge roofing cart can be made using mounting brackets for receiving an elongated support platform. Each bracket includes spaced plates for receiving an axle between the plates on each side thereof and an aperture for receiving an axle pivot pin at one position on the bracket. Each bracket has a plurality of apertures spaced from the pivot aperture for setting the angular position of the axle on each side of the bracket in relationship to the support platform corresponding to standard roof pitch angles. The brackets can be mounted at opposite ends of a support platform to define a cart in which the axles rotatable hold wheels which span the ridge of a roof.
