Actually Gerstlauer's chain lift is more like Intamin's cable lift. Just let the chain replaces the cable.
Correct me if I'm wrong, but the only vertical lift coasters with traditional lift system might be Toboggans(including knock-offs), HRRR, SBF's tower coaster(Including the knock-offs)
Actually, Gerstlauer's Chain Dog System for their Euro Fighters is the same type of system employed by Schwarzkopf on their Looping Stars, Double Loopings, etc.
It's also the same Fahrenheit uses with the difference that it has two.
I know. What I was saying was that the anti roll-back system is traditional, not the chain.
