Stackers are specialized machines used in warehouses and distribution centers to lift and stack pallets of goods. They help optimize space by efficiently organizing products, making it easier for workers to access items when needed. Stackers can be operated manually or powered, and they come in various sizes to accommodate different load capacities. These machines are essential for improving productivity and safety in material handling. By reducing the need for heavy lifting, stackers minimize the risk of injury for workers. They are often used alongside other equipment, such as forklifts and pallet jacks, to streamline operations in logistics.
