It is certainly practical to lift heavy weights with the right pulley system. Years ago I had a building with an elevator that would carry a fully loaded pickup truck up two stories. It operated by pulling a rope. Rather effortless all in all. I wish I had better memory of the flywheels and levers. But it worked great without electricity.
As Jay says, a dumbwaiter should be easy. There are probably some old technical books out there on eBay or Amazon. Audel's might have something on the topic.

Assume the best and ask questions.
