A lifting device is a tool or machine designed to raise, lower, or move heavy objects safely and efficiently. Common examples include cranes, forklifts, and hoists. These devices are essential in construction, manufacturing, and warehouses, helping workers handle materials that would be too heavy or awkward to lift by hand. Lifting devices come in various forms, each suited for specific tasks. For instance, a crane can lift large loads high into the air, while a forklift is perfect for moving pallets around a warehouse. By using these devices, businesses can improve productivity and reduce the risk of injury to workers.
