Speaking of, Iskandar, have you considered adding Pistronics? I've played with it a fair bit and it's both surprisingly fun, and handy. If you were so inclined a Pistronics Elevator seems to work reasonably well, and certainly looks cooler than a ladder. If you can get the rod folder placed right, you can get it to raise and lower storage up and down in the air from the bottom of a mine shaft.
I even got them to open a pair of doors as it rose like the old freight elevators.
