Abstract: The present invention is directed to a twin reel beltwinder which is designed to support an indeterminate length of conveyor belt for transportation within a mine cavity. The present invention includes a frame structure rotatably mounted on four wheels and including a framework for supporting a roll of conveyor belt. The entire roll of conveyor belt is initially positioned on one arm of the support structure. Subsequently, a portion of the conveyor belt is unreeled onto the second arm of the support structure. By equally distributing the conveyor belt between the first arm and the second arm of the support structure, the overall height of the apparatus is low enough to be accommodated within a mine cavity.
