For trap doors or lifting the sacks along the exterior wall of the building this would be the best answer. For a stairway, it has the aforementioned drawbacks. | |

With a block and tackle you also need somewhere that you can tie off the rope so the load stays put, if there's only you doing it, and if you're pulling on the rope from below, unless it has some sort of brake? You have to be able to load the hoist at the bottom then raise it then get upstairs yourself then get the thing off the hoist. It's not as easy as you'd hope. My hoist slides sideways depending on whether my attic ladder is in position or not. | |
