Freight Elevators

We don't know how great pyramids were built, but we are sure that if the Pharaoh had a freight elevator 4000 years ago, the Ancient Egyptian laborers would love him more. It is still not that easy to carry a refrigerator to the 8th floor unless a freight lift exists in the apartment. A fright lift can carry tons of weights, while an average passenger elevator is designed for around 600 kg's of load.
