Dollies are small wheeled platforms used to move heavy objects easily. They come in various shapes and sizes, often featuring a flat surface to support items like furniture or boxes. Dollies are commonly made from materials like wood or metal and can be found in homes, warehouses, and moving companies. There are different types of dollies, including furniture dollies, which have a low profile and can carry large items, and hand trucks, which are designed for vertical lifting. Using a dolly can help prevent injuries and make transporting goods more efficient, especially during moving or renovation projects.
