Lifting devices are machines used to move heavy objects from one place to another. Elevators (9 letters) are vertical transportation systems that move people and goods between floors of a building. HOISTS (6 letters) are mechanical devices used to lift and lower heavy loads, such as in construction or manufacturing. CRANES (6 letters) are large machines used to move heavy objects from one place to another, often over long distances. All three of these lifting devices are essential for many industries and have been used for centuries.
