Rack and pinion and also screw drive systems are available. They may have a place in very specialized applications, but, in my opinion, do not offer any advantage for typical applications.
There are also hybrid systems, i.e., roped hydraulic.

There is one elevator that never in my life time has broken down except in an earthquake. It does't use hydraulics nor ropes, but the old shanks pony? THE STAIRS.
