Dollies are small, wheeled platforms used to move heavy objects easily. They come in various shapes and sizes, often featuring a flat surface to hold items securely. Dollies are commonly used in warehouses, moving companies, and homes to transport furniture, boxes, and equipment without straining the back. There are different types of dollies, including furniture dollies, which have a rectangular shape and can carry large items, and hand trucks, which are upright and designed for stacking boxes. Using a dolly can save time and effort, making it a practical tool for both professionals and DIY enthusiasts.
