Claim:
A material transport system for use with a ladder having at least two ladder rails, the system comprising: a base assembly having a length, and an adjustable width; a material support platform hingedly attached to the base assembly, the platform supportable angularly above the base assembly by at least two support tubes hingedly attached to the base assembly; a left pair and a right pair of rail guides aligned along the length of the base assembly, the rail guides removably attached to the underside of the base assembly; and a left pair and a right pair of wheels axially mounted between each rail guide pair, the bottom edges of the rail guides extending past the bottom edges of the wheels and wherein the left pair of rail guides encloses at least a portion of a first rail of a ladder attachable thereto and the right pair of rail guides encloses at least a portion of a second rail of a ladder attachable thereto; characterized in that the rail guides and wheels enable the transport system to be pulled along the rails of a ladder by wire, rope, or like component attached to the transport system; further including a pair of transition ramps for enabling the system to track on an extension ladder having a wider base section and a narrower extension section, the ramps enabling transition from the wider base section of the ladder to the narrower extension section; wherein the transition ramps are removably attachable to the rails of the narrower extension section of the ladder, the ramps held in position against one or more sides of the rails of the wider base section of the ladder by a keeper feature protruding from the underside of each ramp.
