Three photos are arranged in two rows, labeled (a) and (b) in the top row, and (c) in the bottom row. In the first photo (a) labeled “The empty conveyor for L over U L,” there is an empty conveyor located in the center of the photo. The conveyor is rectangular and runs horizontally across the floor, with several parallel lines visible, indicating the belts on the conveyor. The yellow conveyor frame stands out, and the surrounding space appears to be an industrial area with high ceilings and large windows. On the left side of the photo, a forklift is positioned next to the conveyor, visible behind some boxes or pallets. The second photo (b), labeled “The conveyor loaded with pallets,” shows the same conveyor now loaded with several pallets. The pallets are stacked in a row along the conveyor, occupying most of its length. The pallets are rectangular and made of dark-colored material. The conveyor belt appears to be slightly inclined and is holding the pallets in a steady position, ready for further transportation. The warehouse setting remains consistent, with visible structural elements, such as ceiling fans and bright industrial lights. The third photo (c), labeled “The pallets loaded onto the trailer. Matching conveyors are installed in the trailer,” shows a close-up of a trailer's rear door. The trailer's interior is visible, with pallets loaded inside and resting against the back wall. The pallets are aligned with matching conveyors, which are installed inside the trailer to facilitate the movement of goods from the loading area to the truck. The trailer's entrance is large, with yellow and black striped safety markings at the edges.Images showing the L/UL solution in Case 1
