Abstract: A carrier vehicle supports plural drums of belting material for deployment in the lengthening of conveyor belts in mines with the belting material being in a double thickness having its midpoint over a removable winding rod extending eccentric and parallel to the axis of each drum so that the belting material can be unwound from the drum after its ends are connected to the old belt. A chain extends between the vehicle and the tailpiece of an existing conveyor system so that forward movement of the vehicle unwinds the new belting and moves the tailpiece to a forward extended position simultaneously with a minimum of labor. In a second embodiment, plural rolls of new belting material are supported on a movable vehicle with the belting material being in a single ply but with adjacent rolls being reversely wound so that the belting can be deployed from the upper portion of one roll and the lower portion of an adjacent roll while the vehicle moves the tailpiece to its new location.
