摘要： A utility trailer with a movable bed floor includes a trailer frame supported by a plurality of wheel assemblies. A bed panel is coupled with the trailer frame and defines an upper support surface. A live-bed flexible member spans the length and width of the upper support surface. A load chain is coupled between forward and rearward ends of the live-bed flexible member and span the length of the bed panel below the bed panel. A drive system is supported by the trailer frame. The drive system has a sprocket engaged with the load chain and is operable to drive the live-bed flexible member in forward and rearward directions over the upper support surface for loading and unloading items from the utility trailer.
