Impossible Four

"The impossible is often the untried"-- Jim Goodwin

Lately i heard about accident in my company's warehouse due to some workers trying to get things down from high shelves in a very unsade way. So i thought of thinking of a way that can help people do their job safely.

i thought if we had a ladder like the ones for libraries that are hooked at the top and move on wheels from one side to another. And beside this ladder an dmoving with it would be a set og rails that have a basket (like th ones of kids bicycles) but bigger and stronger that would move up and down mechanically like a firefighters lift. And hence the worker would go up the ladder and press a button to bring the basket up beside him, then he would put anything he wants in the basket and then press the button to send it down while he goes down the ladder empty handed.

Now that i think of it, why not just make an elevator that lifts people up and down anyway! WOuld it be more expensive coz it will need to hold heavier things? I dont know

Does anyone know if this ladder and lift is made already by someone and that i just havent seen this idea beforE?? Do tell me! It might be one impossible... made possible!
