Aside from a dockworker's rigging, doing 4 wires onto a single layer windup
will work fine. A long drum with the 4 wires at steps along the length
which will allow the wire to wrap around in the single layer without hitting
each other is the way to go.
You also need to do some kind of automatic brake in case the wire breaks or
gets loose that you have control of the release of (normally braked and you
have to pull to allow the elevator to go down) should be done to keep things
safe.
