Heavy-Duty Aluminum Diamond Plate Dollies

This set consists of four unidentical heavy-duty dollies, presumably used for moving substantial equipment or items. Each dolly is constructed from diamond plate aluminum, known for its strength-to-weight ratio and slip-resistant surface. The overall color is a dull metallic silver-gray, consistent with aged and used aluminum. Each dolly appears to be roughly rectangular, with two visible corners on each piece having been rounded or curved upwards, though the exact dimensions are not clear from the image. Each dolly is equipped with at least two black casters, visible underneath, indicating mobility. These casters appear to be made of a hard plastic or rubber material, suitable for heavy loads. The diamond plate pattern is clearly visible across the entire surface of each dolly, providing texture and grip. Condition-wise, the dollies show significant signs of wear and heavy use. There is considerable dirt, grime, and what appears to be dried organic matter (possibly mud, soil, or plant debris) caked onto the surfaces, particularly on the bottom right dolly where a large clump of dark, matted material is present. Scratches, scuffs, and abrasions are evident across all surfaces, consistent with their function. Some areas appear discolored or stained, suggesting exposure to various elements or substances. One of the dollies (bottom left) features a white, U-shaped handle, likely for pulling or positioning the dolly, a feature not visibly present on the others. No specific manufacturer's marks, signatures, or stamps are discernible from the provided image. Given the robust construction and utilitarian design, these dollies appear to be industrial or commercial-grade equipment, likely from the latter half of the 20th century to early 21st century. The craftsmanship, though functional, prioritizes durability over aesthetic appeal, characteristic of heavy-duty moving equipment.
